The rules here

💰Upfront deposit

Not required. After winning, fund the account by 15:00 on the deposit deadline.

🎯How the lottery works

Tiered into S, A and B according to your trading record.

🎫The pool open to everyone

At least 10% of the allocation goes to a third draw that includes people with no trading record.

🆓Fees

None, either to apply or to buy.

From applying to owning

  1. Enter the lottery

    You can apply during book building with nothing deposited.

  2. Check the result

    Results are published for the first, second and third draws.

  3. Fund the account

    If you win, deposit at least the offer price multiplied by your shares by 15:00 on the deposit deadline.

  4. Confirm the purchase

    Once the funds are confirmed, complete the purchase. Normally one lot per person.

  5. Wait for the listing day

    Once the purchase is settled, there is nothing left to do.

Worth knowing before you apply

  • Important. The securities business transfers to SBI Securities on 13 October 2026. IPO applications are expected to end with listings in September 2026, and trading services are scheduled to close at 19:00 on 9 October. Check the current official announcements before opening an account now.
  • Winning counts as losing if the money does not arrive by the 15:00 deposit deadline.
  • Applying for the same listing from more than one account may invalidate the applications.

Who this suits

  • People who want a broker underwriting many listings without their funds being tied up
  • People with no trading record who want to start in the third draw, which covers at least 10% of the allocation

Please note

The securities business is scheduled to transfer to SBI Securities on 13 October 2026, announced on 26 March 2026. IPO coverage is expected to run only until listings in September 2026. What follows describes the rules as they stand until the transfer.

Why this one

Nothing needs to be deposited when you apply. Money is only required after you win, by 15:00 on the deposit deadline, and there is no commission to apply or to buy.

The draw is tiered by trading record into S, A and B, but at least 10% of the allocated shares is guaranteed to go to a third draw open to every tier. Someone who has just opened an account still has a real chance.

It draws on the underwriting network of the long-established Okasan Securities group, and has handled a large number of listings as a delegated underwriter.
