TANAKA Growth Fund
|
INVESTMENT OBJECTIVE
|
The Fund's investment objective is growth of capital.
|
FEES AND EXPENSES
|
This table describes the fees and expenses that you may pay if you
buy and hold shares of the Fund.
|
Shareholder Fees (fees paid directly from your investment)
|
|
Annual Fund Operating Expenses (Expenses that you pay each year as a percentage of the value of your investment.)
|
|
Expense Example
|
The following example is intended to help you
compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest
$10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example
also assumes that your investment has a 5% return each year and the Fund's operating expenses remain the same. Although your actual
costs may be higher or lower, based on these assumptions your costs would be:
|
|
PORTFOLIO TURNOVER
|
The Fund pays transaction costs, such as commissions,
when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher
transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected
in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the
Fund’s portfolio turnover rate was 4.94% of the average value of its portfolio.
|
PRINCIPAL INVESTMENT STRATEGIES
|
The Fund employs the following principal investment
strategies:
| · | Normally investing in common stocks and
other equity securities of small, medium and large capitalization companies. |
| · | Investing up to 45% of its net assets,
measured at the time of investment, in foreign securities, including multinational and emerging market securities. The Fund is
a non-diversified fund, which means that the Fund may take larger positions in a small number of companies than a diversified fund. |
| · | Investing in issues which the Fund's investment
Advisor believes have superior capital growth potential. Companies that meet or exceed specific criteria established by the investment
manager in the selection process are purchased. Securities are sold when they reach internally determined pricing targets or no
longer qualify under the manager’s investment criteria. |
While the Fund usually will diversify its investments
across a range of industry sectors, certain sectors are likely to be overweighted compared to others, because the Advisor actively
seeks the best investment opportunities regardless of sector. For example, the Fund may be overweighted at times in the financial
services, technology and/or pharmaceutical/health care sectors. The sectors in which the Fund may be overweighted will vary at
different points in an economic cycle.
The Fund may, from time to time, take temporary
defensive positions that are inconsistent with the Fund’s principal investment strategies in attempting to respond to adverse
market, economic, political, or other conditions. When the Fund takes a defensive position, the Fund’s assets will be held
in cash and/or cash equivalents.
|
PRINCIPAL INVESTMENT RISKS
|
The Fund is subject to the following principal
investment risks:
Management Risk - The Advisor's growth-oriented
investment approach may fail to produce the intended results.
Smaller Company Risk - To the extent
the Fund invests in smaller capitalization companies, the Fund will be subject to additional risks. These include:
| · | The earnings and prospects of smaller companies
are more volatile than larger companies. |
| · | Smaller companies may experience higher
failure rates than do larger companies. |
| · | The trading volume of securities of smaller
companies is normally less than that of larger companies and, |
| · | therefore, may disproportionately affect
their market price, tending to make them fall more in response to selling pressure than is the case with larger companies. |
| · | Smaller companies may have limited markets,
product lines or financial resources and may lack management experience. |
Single Company Investment Risk - Because
the Fund may invest a larger portion of its assets in one or more companies than would a more diversified fund, the value of the
Fund may disproportionately decrease in response to the activities and financial prospects of an individual company in the Fund's
portfolio. The value of an individual company can be more volatile than the market as a whole.
Market Risk – Overall stock market
risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels
and political events affect the securities markets and could cause the Fund's share price to fall.
Foreign Risk - To the extent the Fund
invests in foreign securities, the Fund could be subject to greater risks because the Fund's performance may depend on issues other
than the performance of a particular company. Changes in foreign economies and political climates are more likely to affect the
Fund than a fund that invests exclusively in U.S. companies. The value of foreign securities is also affected by the value of the
local currency relative to the U.S. dollar. There may also be less government supervision of foreign markets, resulting in non-uniform
accounting practices and less publicly available information. Investment in securities of issuers based in underdeveloped emerging
markets entails all of the risks of investing in securities of foreign issuers outlined in this section to a heightened degree.
These heightened risks include: (i) greater risks of expropriation, confiscatory taxation, nationalization, and less social, political
and economic stability; (ii) the smaller size of the market for such securities and a low or nonexistent volume of trading, resulting
in lack of liquidity and in price volatility; (iii) certain national policies which may restrict a Fund's investment opportunities;
and (iv) in the case of Eastern Europe and in China and other Asian countries, the absence of developed capital markets and legal
structures governing private or foreign investment and private property and the possibility that recent favorable economic and
political developments could be slowed or reversed by unanticipated events.
In addition to brokerage commissions, custodial
services and other costs relating to investment in emerging markets are generally more expensive than in the United States. Such
markets historically have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such
transactions.
Non-Diversification Risk - As a non-diversified
fund, the Fund's portfolio may at times focus on a limited number of companies and will be subject to substantially more investment
risk and potential for volatility than a diversified fund.
Sector Risk - If the Fund's portfolio
is overweighted in a certain industry sector, any negative development affecting that sector will have a greater impact on the
Fund than a fund that is not overweighted in that sector. For example, to the extent the Fund is overweighted in the financial
services sector, the technology sector or the pharmaceutical/health care sector, it will be affected by developments affecting
the applicable sector. All three sectors are subject to changing government regulations that may limit profits and restrict services
offered. Companies in these sectors also may be significantly affected by intense competition. In addition, the profitability of
companies in the financial services industries can be significantly affected by the cost of capital and changes in interest rates,
and technology and pharmaceutical/health care products may be subject to rapid obsolescence.
Volatility Risk - Common stocks tend
to be more volatile than other investment choices. The value of an individual company can be more volatile than the market as a
whole. This volatility affects the value of the Fund's shares.

THE FUND'S PAST PERFORMANCE
|
The following bar chart and table below provide
some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and
by showing how the Fund’s average annual returns for 1, 5, and 10 years compare with those of a broad measure of market performance).
The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the
future. Updated performance information is available at www.tanaka.com and by calling toll-free 877-4 TANAKA.
|
YEAR-BY-YEAR ANNUAL RETURNS (FOR CALENDER YEARS ENDING ON DEC. 31)
|
|
During the periods shown, the highest return
for a quarter was 17.10% (3rd quarter, 2013) and the lowest return was -23.41% (4th quarter, 2018).
*2012 includes the effect of one-time class
action litigation settlements accruing to the Fund. If those settlements were not included, performance would have been lower.
|
AVERAGE ANNUAL TOTAL RETURNS (FOR PERIODS ENDING ON DEC. 31 2019)
|
Average Annual Total Returns for the Fund's Class R Shares (for periods
ending on December 31, 2019)
|
|
After-tax returns are calculated using the historical
highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns
depend on an investor's tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who
hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.
The above performance includes the effect of
one-time class action litigation settlements accruing to the Fund in 2012. If those settlements were not included, performance
would have been lower.

- DefinitionRisk/Return Summary Fee Table Includes the following information, in plain English under rule 421(d) under the Securities Act, after Item 2 Fees and expenses of the Fund This table describes the fees and expenses that you may pay if you buy and hold shared of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $[_____] in [name of fund family] funds. Shareholder Fees (fees paid directly from your investment) Example This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be You would pay the following expenses if you did not redeem your shares The Example does not reflect sales charges (loads) on reinvested dividends [and other distributions]. If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds. For purposes of this Item, a "New Fund" is a Fund that does not include in Form N-1A financial statements reporting operating results or that includes financial statements for the Fund's initial fiscal year reporting operating results for a period of 6 months or less.

If the Fund is a Feeder Fund, reflect the aggregate expenses of the Feeder Fund and the Master Fund in a single fee table using the captions provided. In a footnote to the fee table, state that the table and Example reflect the expenses of both the Feeder and Master Funds. If the prospectus offers more than one Class of a Multiple Class Fund or more than one Feeder Fund that invests in the same Master Fund, provide a separate response for each Class or Feeder Fund. Base the percentages of "Annual Fund Operating Expenses" on amounts incurred during the Fund's most recent fiscal year, but include in expenses amounts that would have been incurred absent expense reimbursement or fee waiver arrangements. If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."

If there were expense reimbursement or fee waiver arrangements that reduced any Fund operating expenses and will continue to reduce them for no less than one year from the effective date of the Fund's registration statement, a Fund may add two captions to the table one caption showing the amount of the expense reimbursement or fee waiver, and a second caption showing the Fund's net expenses after subtracting the fee reimbursement or expense waiver from the total fund operating expenses. The Fund should place these additional captions directly below the "Total Annual Fund Operating Expenses" caption of the table and should use appropriate descriptive captions, such as "Fee Waiver [and/or Expense Reimbursement]" and "Total Annual Fund Operating Expenses After Fee Waiver [and/or Expense Reimbursement]," respectively. If the Fund provides this disclosure, also disclose the period for which the expense reimbursement or fee waiver arrangement is expected to continue, and briefly describe who can terminate the arrangement and under what circumstances.

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block] |

The Fund pays transaction costs, such as commissions,
when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher
transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected
in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the
Fund’s portfolio turnover rate was 4.94% of the average value of its portfolio.

$10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example
also assumes that your investment has a 5% return each year and the Fund's operating expenses remain the same. Although your actual
costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] |
rr_StrategyHeading |
PRINCIPAL INVESTMENT STRATEGIES
|
|
Strategy Narrative [Text Block] |
rr_StrategyNarrativeTextBlock |
The Fund employs the following principal investment
strategies:
| · | Normally investing in common stocks and
other equity securities of small, medium and large capitalization companies. |
| · | Investing up to 45% of its net assets,
measured at the time of investment, in foreign securities, including multinational and emerging market securities. The Fund is
a non-diversified fund, which means that the Fund may take larger positions in a small number of companies than a diversified fund. |
| · | Investing in issues which the Fund's investment
Advisor believes have superior capital growth potential. Companies that meet or exceed specific criteria established by the investment
manager in the selection process are purchased. Securities are sold when they reach internally determined pricing targets or no
longer qualify under the manager’s investment criteria. |
While the Fund usually will diversify its investments
across a range of industry sectors, certain sectors are likely to be overweighted compared to others, because the Advisor actively
seeks the best investment opportunities regardless of sector. For example, the Fund may be overweighted at times in the financial
services, technology and/or pharmaceutical/health care sectors. The sectors in which the Fund may be overweighted will vary at
different points in an economic cycle.
The Fund may, from time to time, take temporary
defensive positions that are inconsistent with the Fund’s principal investment strategies in attempting to respond to adverse
market, economic, political, or other conditions. When the Fund takes a defensive position, the Fund’s assets will be held
in cash and/or cash equivalents.
|
|
Risk [Heading] |
rr_RiskHeading |
PRINCIPAL INVESTMENT RISKS
|
|
Risk Narrative [Text Block] |
rr_RiskNarrativeTextBlock |
The Fund is subject to the following principal
investment risks:
Management Risk - The Advisor's growth-oriented
investment approach may fail to produce the intended results.
Smaller Company Risk - To the extent
the Fund invests in smaller capitalization companies, the Fund will be subject to additional risks. These include:
| · | The earnings and prospects of smaller companies
are more volatile than larger companies. |
| · | Smaller companies may experience higher
failure rates than do larger companies. |
| · | The trading volume of securities of smaller
companies is normally less than that of larger companies and, |
| · | therefore, may disproportionately affect
their market price, tending to make them fall more in response to selling pressure than is the case with larger companies. |
| · | Smaller companies may have limited markets,
product lines or financial resources and may lack management experience. |
Single Company Investment Risk - Because
the Fund may invest a larger portion of its assets in one or more companies than would a more diversified fund, the value of the
Fund may disproportionately decrease in response to the activities and financial prospects of an individual company in the Fund's
portfolio. The value of an individual company can be more volatile than the market as a whole.
Market Risk – Overall stock market
risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels
and political events affect the securities markets and could cause the Fund's share price to fall.
Foreign Risk - To the extent the Fund
invests in foreign securities, the Fund could be subject to greater risks because the Fund's performance may depend on issues other
than the performance of a particular company. Changes in foreign economies and political climates are more likely to affect the
Fund than a fund that invests exclusively in U.S. companies. The value of foreign securities is also affected by the value of the
local currency relative to the U.S. dollar. There may also be less government supervision of foreign markets, resulting in non-uniform
accounting practices and less publicly available information. Investment in securities of issuers based in underdeveloped emerging
markets entails all of the risks of investing in securities of foreign issuers outlined in this section to a heightened degree.
These heightened risks include: (i) greater risks of expropriation, confiscatory taxation, nationalization, and less social, political
and economic stability; (ii) the smaller size of the market for such securities and a low or nonexistent volume of trading, resulting
in lack of liquidity and in price volatility; (iii) certain national policies which may restrict a Fund's investment opportunities;
and (iv) in the case of Eastern Europe and in China and other Asian countries, the absence of developed capital markets and legal
structures governing private or foreign investment and private property and the possibility that recent favorable economic and
political developments could be slowed or reversed by unanticipated events.
In addition to brokerage commissions, custodial
services and other costs relating to investment in emerging markets are generally more expensive than in the United States. Such
markets historically have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such
transactions.
Non-Diversification Risk - As a non-diversified
fund, the Fund's portfolio may at times focus on a limited number of companies and will be subject to substantially more investment
risk and potential for volatility than a diversified fund.
Sector Risk - If the Fund's portfolio
is overweighted in a certain industry sector, any negative development affecting that sector will have a greater impact on the
Fund than a fund that is not overweighted in that sector. For example, to the extent the Fund is overweighted in the financial
services sector, the technology sector or the pharmaceutical/health care sector, it will be affected by developments affecting
the applicable sector. All three sectors are subject to changing government regulations that may limit profits and restrict services
offered. Companies in these sectors also may be significantly affected by intense competition. In addition, the profitability of
companies in the financial services industries can be significantly affected by the cost of capital and changes in interest rates,
and technology and pharmaceutical/health care products may be subject to rapid obsolescence.
Volatility Risk - Common stocks tend
to be more volatile than other investment choices. The value of an individual company can be more volatile than the market as a
whole. This volatility affects the value of the Fund's shares.

If the Fund is a Feeder Fund, reflect the aggregate expenses of the Feeder Fund and the Master Fund in a single fee table using the captions provided. In a footnote to the fee table, state that the table and Example reflect the expenses of both the Feeder and Master Funds. If the prospectus offers more than one Class of a Multiple Class Fund or more than one Feeder Fund that invests in the same Master Fund, provide a separate response for each Class or Feeder Fund. Base the percentages of "Annual Fund Operating Expenses" on amounts incurred during the Fund's most recent fiscal year, but include in expenses amounts that would have been incurred absent expense reimbursement or fee waiver arrangements. If the Fund has changed its fiscal year and, as a result, the most recent fiscal year is less than three months, use the fiscal year prior to the most recent fiscal year as the basis for determining "Annual Fund Operating Expenses."

If there were expense reimbursement or fee waiver arrangements that reduced any Fund operating expenses and will continue to reduce them for no less than one year from the effective date of the Fund's registration statement, a Fund may add two captions to the table one caption showing the amount of the expense reimbursement or fee waiver, and a second caption showing the Fund's net expenses after subtracting the fee reimbursement or expense waiver from the total fund operating expenses. The Fund should place these additional captions directly below the "Total Annual Fund Operating Expenses" caption of the table and should use appropriate descriptive captions, such as "Fee Waiver [and/or Expense Reimbursement]" and "Total Annual Fund Operating Expenses After Fee Waiver [and/or Expense Reimbursement]," respectively. If the Fund provides this disclosure, also disclose the period for which the expense reimbursement or fee waiver arrangement is expected to continue, and briefly describe who can terminate the arrangement and under what circumstances.
