Entering from overseas

INBOUND

Overseas entry not available

How to enter

Entry via RUNNET (online) or a dedicated postal transfer form (paper). The postal transfer form requires a Japanese mailing address to receive and submit it, making it impractical for overseas runners.

Entry platform

RUNNET

What you need

RUNNET free membership registration required for online entry. The postal transfer form option requires requesting the form by post to a Japanese address.

Payment

Credit card, convenience store, or ATM (via RUNNET). Postal transfer via Japan Post for the paper form. A RUNNET handling fee applies (¥240 up to ¥4,000; 6% for amounts over ¥4,001).

Bib pickup

No race-day registration or bib pickup — bibs and timing chips are mailed to participants in advance (around August 30). If the bib does not arrive, runners must contact the race office. A Japanese delivery address is effectively required.

Entry period

Online (RUNNET): until August 7, 2026. Postal transfer form: until July 31, 2026.

Notes

Because bibs are mailed to participants before the race and no race-day pickup is available, a Japanese delivery address is effectively required. This makes entry impractical for overseas runners without a Japanese address.
