What this is
Riding the Shinkansen becomes the mystery itself — this JR Central collaboration turns Tokaido Shinkansen trains into a live Detective Conan puzzle game running from August through November 2026. Passengers access a campaign website from inside the train to unlock five questions, and solving all of them correctly earns a boarding certificate. Take that certificate to Sanseido Bookstore's Nagoya Main Store to claim a random original acrylic keychain, and boarding the train also unlocks a time-limited AR photo frame usable until midnight the following day.
Who should go
Detective Conan fans travelling on the Tokaido Shinkansen — especially those already making a trip between Tokyo, Nagoya, or Osaka. Kids and parents who enjoy interactive scavenger-hunt style activities will get the most out of it.
Good to know
No separate ticket is needed for the campaign itself — participation is free as long as you hold a valid Tokaido Shinkansen boarding ticket. Access the campaign website from your smartphone while on the train; mobile data should work throughout most of the route, but connectivity can briefly drop in tunnels, so load the page once you have a stable signal. The AR photo frame expires at 23:59 the day after your boarding date, so use it promptly. For the keychain reward, Sanseido Bookstore Nagoya Main Store is a short walk from Nagoya Station — confirm opening hours before visiting as stock and availability may vary across the campaign period.
