The example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that 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:

	One year	Three years	Five years	Ten years
Investor Class	$111	$347	$601	$1,329
Institutional Class	$104	$325	$563	$1,248

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 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 of fund expenses, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 101% of the average value of its portfolio.

Principal Investment Strategy

Under normal circumstances, the Matthews Japan Fund seeks to achieve its investment objective by investing at least 80% of its net assets, which include borrowings for investment purposes, in the common and preferred stocks of companies located in Japan. A company or other issuer is considered to be “located” in a country or a region,

PS-MJFOX/MIJFX-0424

and a security or instrument is deemed to be an Asian (or specific country) security or instrument, if it has substantial ties to that country or region. Matthews currently makes that determination based primarily on one or more of the following criteria: (A) with respect to a company or issuer, whether (i) it is organized under the laws of that country or any country in that region; (ii) it derives at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed, or has at least 50% of its assets located, within that country or region; (iii) it has the primary trading markets for its securities in that country or region; (iv) it has its principal place of business in or is otherwise headquartered in that country or region; or (v) it is a governmental entity or an agency, instrumentality or a political subdivision of that country or any country in that region; and (B) with respect to an instrument or issue, whether (i) its issuer is headquartered or organized in that country or region; (ii) it is issued to finance a project that has at least 50% of its assets or operations in that country or region; (iii) it is at least 50% secured or backed by assets located in that country or region; (iv) it is a component of or its issuer is included in the MSCI Japan Index, the Fund’s primary benchmark index; or (v) it is denominated in the currency of an Asian country and addresses at least one of the other above criteria. The term “located” and the associated criteria listed above have been defined in such a way that Matthews has latitude in determining whether an issuer should be included within a region or country. The Fund may also invest in depositary receipts, including American, European and Global Depositary Receipts.

The Fund seeks to invest in companies capable of sustainable growth based on the fundamental characteristics of those companies, including balance sheet information; number of employees; size and stability of cash flow; management’s depth, adaptability and integrity; product lines; marketing strategies; corporate governance; and financial health. The Fund may invest in companies of any market capitalization. Matthews measures a company’s size with respect to fundamental criteria such as, but not limited to, market capitalization, book value, revenues, profits, cash flow, dividends paid and number of employees. The implementation of the principal investment strategies of the Fund may result in a significant portion of the Fund’s assets being invested from time to time in one or more sectors, but the Fund may invest in companies in any sector.

Principal Risks of Investment

There is no guarantee that your investment in the Fund will increase in value. The value of your investment in the Fund could go down, meaning you could lose money. The principal risks of investing in the Fund are:

Political, Social and Economic Risks of Investing in Asia: The value of the Fund’s assets may be adversely affected by political, economic, social and religious instability; inadequate investor protection; changes in laws or regulations of countries within the Asian region (including countries in which the Fund invests, as well as the broader region); international relations with other nations; natural disasters; corruption and military activity. The economies of many Asian countries differ from the economies of more developed countries in many respects, such as rate of growth, inflation, capital reinvestment, resource self-sufficiency, financial system stability, the national balance of payments position and sensitivity to changes in global trade.

Geopolitical Events Risk: The interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund’s portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on the global financial markets.

Currency Risk: When the Fund conducts securities transactions in a foreign currency, there is the risk of the value of the foreign currency increasing or decreasing against the value of the U.S. dollar. The value of an investment denominated in a foreign currency will decline in U.S. dollar terms if that currency weakens against the U.S. dollar. While the Fund is permitted to hedge currency risks, Matthews does not anticipate doing so at this time.

Risks Associated with Japan: The Japanese economy has only recently emerged from a prolonged economic downturn. Since the year 2000, Japan’s economic growth rate has remained relatively low. The Japanese economy is characterized by an aging demographic, declining population, large government debt and highly regulated labor market. Economic growth in Japan is dependent on domestic consumption, deregulation and consistent government policy. International trade, particularly with the U.S., also impacts growth of the Japanese economy and adverse economic conditions in the U.S. or other trade partners may affect Japan. Japan also has a growing economic relationship with China and other Southeast

Asian countries, and thus Japan’s economy may also be affected by economic, political or social instability in those countries (whether resulting from local or global events). Other factors, such as the occurrence of natural disasters and relations with neighboring countries (including China, South Korea, North Korea and Russia), may also negatively impact the Japanese economy.

Growth Stock Risk: Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions of the issuing company’s growth potential. Growth stocks may go in and out of favor over time and may perform differently than the market as a whole.

Equity Securities Risk: Equity securities may include common stock, preferred stock or other securities representing an ownership interest or the right to acquire an ownership interest in an issuer. Equity risk is the risk that stocks and other equity securities generally fluctuate in value more than bonds and may decline in value over short or extended periods. The value of stocks and other equity securities may be affected by changes in an issuer’s financial condition, factors that affect a particular industry or industries, or as a result of changes in overall market, economic and political conditions that are not specifically related to a company or industry.

Preferred Stock Risk: Preferred stock normally pays dividends at a specified rate and has precedence over common stock in the event the issuer is liquidated or declares bankruptcy. However, in the event a company is liquidated or declares bankruptcy, the claims of owners of bonds take precedence over the

MATTHEWS JAPAN FUND 2

claims of those who own preferred and common stock. If interest rates rise, the dividend on preferred stocks may be less attractive, causing the price of such stocks to decline.

Depositary Receipts Risk: Although depositary receipts have risks similar to the securities that they represent, they may also involve higher expenses and may trade at a discount (or premium) to the underlying security. In addition, depositary receipts may not pass through voting and other shareholder rights, and may be less liquid than the underlying securities listed on an exchange.

Risks Associated with Medium-Size Companies: Medium-size companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.

Risks Associated with Smaller Companies: Smaller companies may offer substantial opportunities for capital growth; they also involve substantial risks, and investments in smaller companies may be considered speculative. Such companies often have limited product lines, markets or financial resources. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and the securities of smaller companies generally are subject to more abrupt or erratic price movements than more widely held or larger, more established companies or the market indices in general.

Active Management Risk: The Fund is actively managed by Matthews. There is the risk that Matthews may select securities that underperform the relevant stock market(s), the Fund’s benchmark index or other funds with similar investment objectives and investment strategies.

Sector Concentration Risk: To the extent that the Fund emphasizes, from time to time, investments in a particular sector, the Fund will be subject to a greater degree to the risks particular to that sector, including the sector described below. Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single sector. By focusing its investments in a particular sector, the Fund may face more risks than if it were diversified broadly over numerous sectors.

– Information Technology Sector Risk: As of December 31, 2023, 22% of the Fund’s assets were invested in the information technology sector. Information technology companies may be significantly affected by aggressive pricing as a result of intense competition and by rapid product obsolescence due to rapid development of technological innovations and frequent new product introduction. Other factors, such as short product cycle, possible loss or impairment of intellectual property rights, and changes in government regulations, may also adversely impact information technology companies.

– Industrial Sector Risk: As of December 31, 2023, 21% of the Fund’s assets were invested in the industrial sector. Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies.

– Consumer Discretionary Sector Risk: As of December 31, 2023, 20% of the Fund’ assets were invested in the consumer discretionary sector. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall local and international economies, interest rates, competition and consumer confidence. Success of companies in the consumer discretionary sector depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products and services in the marketplace.

High Portfolio Turnover Risk: The Funds’ distributions principal investment strategies may result in high portfolio turnover rates, which may increase the Fund’s brokerage commission costs and negatively impact the Fund’s performance. Such portfolio turnover also may generate higher taxable gains for shareholders of the Fund.

Cybersecurity Risk: With the increased use of technologies such as the internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers may cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.
