You’ll fill in the gaps for each postcard and help your mysterious employer create a detailed database of Tokyo’s history, all based on real historical sources.

Meet a cast of wandering spirits, identify the truth in their lies, and unlock their stories.

You won’t be alone as you explore Tokyo. A supernatural dam has burst, spilling confused ghosts from the Iron Age to the 1980s across the city. As they tell their stories, not everything they say will add up.

• Encounter spirits of the "Edokko" ("children of Tokyo") at new and old locations as you explore the city.
• Build up their story bit-by-bit in the Spirit Report.
• Explore 15 hand-crafted narratives each telling the story of a single day in Tokyo's long history.
• Use the Encyclopedia and your personal experience of Tokyo to identify the errors and lies.
• Chigau! I object! J'accuse! Highlight the inconsistencies and catch them out to help them clear up their memories.
• Each time you submit a Spirit Report, you'll build up trust with the spirit and unlock more of their backstory, based on the real lives of the Edokko: there are five uniquely-written spirits to meet, from flirty courtesan Kasuga-dono to bubble-bound salaryman Yoshida-san.
• After you finish the main storyline, continue playing in the post-game to unlock all 15 narratives and character stories.

As a roving researcher, take photographs and collect evidence detailing the real history of Tokyo on a sumptuously detailed map.

You're not just a desk jockey. Each week, with PDA and digital camera in hand, you’ll set out from your office to visit three new locations.

• Go by foot or by train from your home base in Marunouchi to view each postcard in its real-world geographical context across four maps: Central Tokyo, Downtown Marunouchi, Tama River and Haneda.
• Discover each location using your PDA Directory and a nearby station's Location Board.
• Revisit old haunts based on paranormal analysis to discover new stories for the Spirit Report.
• Plot a route to some of the most famous Tokyo landmarks:

Ginza

• Asakusa Sensō-ji Temple
• Ueno Station
• Shinjuku Street
• Haneda Airport
• Meiji Shrine

And many more!

• Unlock new evidence by visiting special points around the map.

Compare 1930s images with real photos taken in 2025 at the same locations. Find what’s new – and what’s old – in this mercurial, ever-changing city.

• Use the Similarity Finder to precisely line up present-day photographs with the original postcards.
• With the Time Loupe in Direct Mode, compare past and present and identify common features.
• In Parallels Mode, tease out the tiniest similarities in views that have changed almost completely since 1935.
• And in the Treasure Browser, unlock ten hand-crafted artefacts in glorious 360 degree 3D, each telling their own story of the Imperial Capital: from a "Galapagos phone" to a samurai sword.

Explore an authentic recreation of Tokyo, past and present.

For lovers of Tokyo, this might just be the most authentic interactive recreation ever made.

• Painstaking research reveals the history behind a set of antique 1930s postcards, discovered at a flea market in Shibuya and scanned in high quality.
