The lantern-lit alleys and neon avenues of central Tokyo become a stage for deduction as you tap through a Sherlock Holmes–style murder mystery on your phone. You begin at a recognizable urban node, phone in hand, and the city’s streets rearrange themselves into clues — shopfronts, side streets and river promenades all playing parts in a two-hour investigation.
Tokyo sits on the Kanto Plain, a low-lying, sediment-filled basin shaped by rivers and earthquake activity; that geology explains the city's layered development where modern towers rise beside older wooden shops. The game borrows that layered urban history: puzzles reference Edo-era routes, postwar reconstruction, and Japan’s deep love of detective fiction — think Arthur Conan Doyle refracted through the logic of Edogawa Rampo and modern Japanese mystery writers.
Culturally, the experience is light on exposition and heavy on observation: you'll read cultural signposts, pass small neighborhood shrines, and see how public space is used differently here. The city game encourages slow walking, courteous behavior, and curiosity toward local businesses.
Practical guidance: download the required app and fully charge your phone before starting; data and GPS keep the story moving. Expect about 2 hours of mostly flat walking, some short stairways and crowded sidewalks. Play in daylight for easiest navigation; bring a portable battery, water, and comfortable shoes. Respect private property and quiet residential streets—this is a game played in a living city, not a closed set. With attention and a few clever inferences, the plot will yield to close observation and teamwork.
After booking you’ll receive instructions by email; download the Loquiz app, follow the setup steps, and begin at the suggested start location any time on your chosen date.
One ticket covers 1–4 players per device; larger groups should purchase additional tickets and split into teams.
Yes — the game is rated easy and family-friendly, but younger kids may need help with reading clues and using the app.
Much of the route uses public sidewalks and flat surfaces, but some sections may include steps or narrow alleys; check accessibility for the specific start area in advance.
