A foreign angel can invest in Japanese and Korean startups, but expect more formality than in the US. Paperwork is mostly local-language, foreign-investment filings are common, and both governments shape the funding market. Exits come more often through local IPOs than acquisitions. Find a trusted local co-investor, confirm the instrument and entity, and plan for currency risk.
Japan and South Korea are two of the largest economies in Asia, with deep engineering talent, strong consumer markets and governments that have made startups a policy priority. They also work differently from Silicon Valley in ways that matter to an outside angel: how deals are documented, who else sits on the cap table, how money crosses the border, and how investors eventually get paid. Here's what to know about each, then what they share.
Japan: what's different for a foreign angel?
Policy tailwinds. The Japanese government declared 2022 the first year of a startup push and published a Startup Development Five-Year Plan in November 2022, with a target of greatly increasing annual startup investment by 2027. Programs such as METI's J-Startup, launched in 2018, highlight promising companies. Public money and corporate money are a large part of the market.
Corporate investors everywhere. Corporate venture capital arms are unusually active in Japan, and a round may include a trading house, a bank-affiliated fund and an industrial company alongside independent venture firms. Names you'll run into include JAFCO, one of Japan's oldest venture firms, Global Brain and Coral Capital. Corporate investors can bring customers and distribution, but they may also have strategic interests that differ from yours.
The instruments. Most startups are kabushiki kaisha (KK), a stock company. For early convertible rounds, Japan has J-KISS, a SAFE-like template first published in 2016 by the team now known as Coral Capital. Priced rounds use Japanese-law shareholder agreements, and the share issuance is registered with the Legal Affairs Bureau. Documents and meetings are often in Japanese, so budget for translation and a local lawyer.
Foreign investment rules. Japan's Foreign Exchange and Foreign Trade Act (FEFTA) requires foreign investors to file prior notifications or after-the-fact reports for many investments, with closer scrutiny in designated sectors such as cybersecurity, telecoms and defense-related technology. A small angel stake often only needs a report, but ask the company's counsel which applies, because filings can affect the closing timeline.
Exits lean toward IPOs. Many Japanese startups exit by listing on the Tokyo Stock Exchange's Growth Market, the segment that replaced Mothers in the 2022 market restructuring. Mercari, for example, listed on Mothers in 2018. Startups often list at an earlier stage and smaller size than US companies would, and acquisitions have traditionally been a smaller share of exits. That's changing slowly, but plan your expectations around a listing.
Currency. The yen fell to its weakest level against the dollar in decades in 2024. For a dollar-based angel, that can make entry cheaper and exits worth less. Nobody can forecast where it goes next, so treat yen exposure as part of the bet.

South Korea: what's different for a foreign angel?
A government-backed market. Korea's Ministry of SMEs and Startups runs a large share of the startup support system. The Korea Venture Investment Corporation manages the government's fund of funds, which backs many local venture firms, and the TIPS program, running since 2013, pairs private early-stage investment with government R&D funding for selected startups. Accelerators such as SparkLabs and Primer are common entry points, and the K-Startup Grand Challenge brings foreign founders into the country.
Large groups as investors and buyers. Korea's big business groups and internet companies, such as Naver and Kakao, invest in startups and buy them. A Korean round may include a corporate investor whose plans shape the company's options.
The instruments. Most startups are stock companies (chusik hoesa). Korea added a SAFE-style instrument to its venture investment law in 2020, known as a conditional equity investment agreement, but priced equity rounds, including redeemable convertible preferred shares, remain common. Read the redemption terms carefully; they behave differently from US preferred stock.
Money in and money out. Foreign investment of 10% or more of a Korean company's voting shares, with at least 100 million won invested, counts as foreign direct investment under the Foreign Investment Promotion Act and must be reported. Smaller stakes still go through Korea's foreign exchange reporting rules, usually handled by a designated foreign exchange bank. The won isn't traded freely offshore, so sending funds in and getting proceeds out takes paperwork and time.
Exits. Many Korean startups aim for KOSDAQ, which has a technology special listing track for companies that aren't yet profitable. Some of the country's largest outcomes have taken other routes: Coupang, which has a US parent company, listed on the New York Stock Exchange in 2021, and Delivery Hero agreed to buy Woowa Brothers, the company behind the Baemin delivery app, in a deal announced in 2019. Ask a Korean founder early whether they plan a domestic listing, a US structure or a sale.
What the two markets have in common
Relationships open doors. Warm introductions through a local investor, accelerator or founder matter more than cold outreach. Meeting in person, more than once, is often part of building trust.
Local co-investors do the heavy lifting. As a foreign angel, your best position is usually alongside a respected local lead who handles filings, translation and governance.
Tax incentives are for locals. Both countries offer tax breaks to individuals who invest in startups, but they're aimed at resident taxpayers. A foreign angel normally pays tax on gains at home, subject to the tax treaty between the two countries.
Global ambitions change the structure. Companies built to sell abroad sometimes set up a US or Singapore parent. My guides on how founders raise from international investors and raising venture capital as a non-US founder explain why founders do this and what it means for the cap table.
A short checklist before investing
Confirm the entity: a local KK or chusik hoesa, or a foreign parent company.
Get the instrument and shareholder agreement translated, and read redemption and liquidation terms in full.
Ask the company's counsel which foreign-investment filings or reports your investment triggers.
Find out who leads the round and which corporate or government-backed investors are on the cap table.
Ask the founders which exit route they plan: a local IPO, a US listing or a sale.
Treat currency movement as part of the risk, and size the check accordingly.
The rule is the same everywhere: the team and the market decide the outcome, and the structure decides how much of it reaches you. Structures, currency and tax across borders are covered in the international angel investing guide.

Frequently Asked Questions
Q:Can a foreigner invest in a Japanese startup?
Yes. Foreign individuals and funds invest in Japanese startups regularly. Depending on the company's sector, you may need to file a prior notification or a post-investment report under Japan's foreign exchange law, which the company's lawyers usually handle.
Q:Is there a SAFE in Japan or Korea?
Japan has J-KISS, a SAFE-like convertible template first published in 2016. Korea added a conditional equity investment agreement to its venture investment law in 2020. Both exist alongside priced rounds, which remain common in both countries.
Q:Do I have to report an investment in a Korean startup?
Usually, yes. A stake of 10% or more with at least 100 million won counts as foreign direct investment and is reported under the Foreign Investment Promotion Act, and smaller investments still go through foreign exchange reporting at a bank.
Q:How do Japanese startups usually exit?
Mostly through IPOs on the Tokyo Stock Exchange's Growth Market, often at an earlier stage than US companies would list. Acquisitions are growing but have traditionally been a smaller share of exits.
Q:Should I invest in Japanese or Korean startups through a syndicate?
For a first deal, it often helps. A lead with a local presence handles filings, translation and governance, and can tell you which corporate investors are on the cap table and why.
