Tobu Railway Nazo Tabi Techo: Secret Downtown Edition

Tobu Railway, in cooperation with RIDDLER Inc., will hold "Tobu Railway Nazo Tabi Techo: Secret Downtown Edition," a riddle-solving game that takes players around the Tobu Line. The event runs from Wednesday, November 18, 2026 to Wednesday, June 30, 2027.

It is an interactive walking game in which players keep memories, such as stamps and photos from the places they visit while solving riddles, in a scrapbook.

Story

A mysterious cat in a big hat appears reflected in a train window. Leaving the words "Have you forgotten something?", the cat vanishes, leaving only a blank scrapbook and a notebook filled with codes. What is the "something forgotten" the cat speaks of? Explore the town, collect fragments of your journey, and unravel the mystery.
