Entering from overseas

INBOUND

Possible via an entry platform

How to enter

Online entry via RUNNET only (no postal entry). A free RUNNET account is required to register.

Entry platform

RUNNET (runnet.jp)

What you need

Runners must be 19 or older on race day and capable of finishing 100 km within 13 hours (or 50 km within 8 hours). No specific overseas-runner restrictions are mentioned, but a RUNNET account and payment via Japanese methods (credit card, convenience store, ATM) are required.

Payment

Entry fee is ¥21,000 (100 km) or ¥15,000 (50 km), including insurance and food. A separate pre-shipment fee of ¥1,000 applies. Payment options include credit card, convenience store, or ATM, selected at time of entry.

Bib pickup

Race kits (including bib) are mailed to participants' home addresses in early June — no in-person pickup required.

Entry period

General entry: 20:00 on 26 January 2026 to 23:59 on 13 February 2026, on a first-come, first-served basis.

On race day

Aid stations with food and drinks are provided every 5 km from the 20 km mark. A rest station at approximately 55 km allows runners to retrieve pre-deposited bags.

Notes

Bibs are mailed to the registered address, so overseas runners should ensure they have a deliverable Japanese address or make alternative arrangements. The pre-shipment fee of ¥1,000 is noted separately. Payment via convenience store or ATM may not be practical from overseas; credit card is likely the most accessible option.
