Gumi-bo stamp booth has a maintenance workaround

Bike.go’s Gumi-bo notice says stamp imprinting at the unmanned certification booth is temporarily suspended during refurbishment, with photo proof accepted at staffed centers

Jun 7, 2026

If you need the Gumi-bo stamp, take photo proof of yourself, your bike, and Gumi-bo, then show it at a staffed certification center.

Bike.go’s Gumi-bo notice says stamp imprinting at the unmanned certification booth is temporarily suspended during refurbishment, with photo proof accepted at staffed centers.

What To Do

Bike.go says riders who need the Gumi-bo stamp during the maintenance period should take a photo showing:

yourself. your bike. Gumi-bo.

Show that photo at a staffed certification center. The notice says it will be recognized as stamp proof while the booth is under maintenance.

Useful Details

The official notice does not give a fixed end date. It says the temporary arrangement runs from January 10, 2026 until after the refurbishment.

That means the boring advice is the correct advice: take the photo before leaving the area.

TL;DR

  • Bike.go’s January 13 notice says the Gumi-bo unmanned certification booth is being refurbished.
  • Stamp imprinting has been temporarily suspended since January 10, 2026.
  • Photo proof is accepted at staffed certification centers.

Small problem. Easy to miss.

If you are collecting stamps, do not assume the booth will work normally when you arrive.
