Japanese IPOs, explained in English

For foreign residents of Japan who want to join IPO lotteries

This site tracks every IPO on the Japanese market — the schedule, the offer price, the brokers underwriting it, and what the shares actually did on their first day of trading. The detailed pages are in Japanese. These English pages cover the parts you need to decide whether Japanese IPOs are worth your time.

First, the honest answer: can you take part?

Only if you live in Japan. Japanese IPO shares are allocated through brokerage accounts, and those accounts require a Japanese address. If you are reading this from outside Japan, you cannot join these lotteries — not through an international broker either, because IPO allocations do not reach them.

If you do live in Japan, your nationality is not the obstacle. As an example, SBI Securities states that a foreign national can open an account with a residence card (or special permanent resident certificate) valid for at least two more months, an identity document showing a Japanese address, and a My Number. US citizens, green card holders and US residents face restrictions on some products.

Requirements differ between brokers and change over time. Always check the broker's own current guidance before applying.

Reading from abroad? The listing results and the market data below are still worth a look — Japanese IPOs are unusual in how consistently they price below where they open, and that pattern says something about how the market works.

Why people do this

In a Japanese IPO you buy at a fixed offer price decided before listing. On the listing day the shares open at whatever the market decides — the first traded price. When the first traded price is above the offer price, selling straight away produces a gain.

Across the 23 listings recorded on this site, 14 opened above their offer price (61%), and the average change was +26.9%. Some open below the offer price, and those are included in that figure. Past results do not predict future ones.

Because demand exceeds supply, allocation is by lottery. You will lose most of the time. The way to improve your odds is to hold accounts at several brokers and apply consistently.

How it works

  1. Open accounts at brokers that underwrite IPOs.
  2. When a company is approved for listing, apply during the book building period — usually about one week.
  3. The lottery is drawn. You are told whether you won.
  4. If you won, confirm the purchase and pay. Some brokers require a separate confirmation step — miss it and the shares are gone.
  5. On the listing day you can sell at the opening price, or hold.

Where to open an account

This site scores brokers out of 100 on how accessible their IPO lottery is to someone without a large balance: how equal the lottery is, whether money must be deposited before applying, how many IPOs they handle, whether losses accumulate toward future draws, and their record as lead underwriter. The same scoring is used on the Japanese pages.

These broker pages are in Japanese. The score, the lottery type and the deposit requirement are the parts that matter most, and they are summarised above.

Japanese terms you will meet

Broker websites and application screens are in Japanese. These are a few of the words that decide whether you can finish an application.

新規公開株 / IPO (shinki koukai kabu)
IPO — shares of a company listing on the stock exchange for the first time.
ブックビルディング (book building)
The application period. You state how many shares you want and at what price. This is the step you must not miss.
抽選 (chuusen)
Lottery. Demand almost always exceeds supply, so shares are allocated by lottery.
公開価格 (koukai kakaku)
Offer price. The fixed price you pay if you win the lottery.
初値 (hatsune)
First traded price on the listing day. If it is higher than the offer price, selling immediately produces a gain.

幹事証券 / 主幹事証券 (kanji shouken / shukanji shouken)
Underwriter / lead underwriter. You can only apply through a broker that is underwriting that IPO. The lead underwriter receives the largest allocation.
購入申込 (kounyuu moushikomi)
