ETHGlobal Tokyo 2026
This edition ended on 27 September 2026. The next dates are not published yet; the eSIM below works for any trip to Japan.
Three days of building, and every wallet prompt, 2FA code and team chat runs through your phone. Sort the data before the flight.
Unlimited for the week: a hackathon burns data, and the venue Wi-Fi is shared by every laptop in the hall.
Only in for the three hackathon days?
日程
The hackathon, Friday to Sunday, at Toranomon Hills Forum.
Dates as published on ethglobal.com and ethtokyo.org, checked 15 September 2026. Hacker applications and tickets are on ethglobal.com. We sell the eSIM, not the ticket, and are not affiliated with ETHGlobal.

理由
Venue Wi-Fi is shared by every laptop in the hall. When it slows at 2am, your phone's own data is the backup.
Wallet confirmations, 2FA codes and deploy alerts land on your phone, not your laptop.
Maps, train times and a late ramen near Toranomon all need data the moment you step off the platform.
会場
Toranomon Hills Forum, 1-23-3 Toranomon, Minato City, Tokyo.
Toranomon Hills Station, Tokyo Metro Hibiya Line.
Install the eSIM on home Wi-Fi. The arrivals hall is the one place you will not have any.
確認

If an EID appears, your phone takes an eSIM.
No EID? Don't buy this. The airport counters at Narita, Haneda and Kansai sell physical SIMs.
質問
Not at purchase. Each plan says at checkout whether its days begin when you install it or when it first connects in Japan.
About two minutes. We email a QR code; scan it before you fly and forget about it.
One-for-one replacement, and any unused plan is refunded.
It depends on the plan, and checkout shows it before you pay. Hotspot uses the same data.
