Mysteries of Old Tokyo

Here is an excerpt from Mysteries of Old Tokyo's description on Steam:

In Mysteries of Old Tokyo, you’re the brand new investigator for the Tokyo branch of the secretive Rare Items Acquisitions Ltd. Puzzle your way through 11 chapters that each explore a different aspect of the city's history.

Mysteries of Old Tokyo is inspired by the CD-ROM "multimedia experiences" of the 1990s like Encarta '96 and Cosmology of Kyoto, as well as modern detective games like The Roottrees are Dead and the Golden Idol series.

• Review the evidence, answer the questions, and help complete an unrivalled, meticulously researched database of Tokyo.
• Meet a cast of wandering spirits, identify the truth in their lies, and unlock their stories.
• As a roving researcher, take photographs and collect evidence detailing the real history of Tokyo on a sumptuously detailed 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.
• Defeat the supernatural threat and save Tokyo in a story spanning 11 chapters.
