Gather clues, collect treasures and unlock over 40 real-life locations in an authentic recreation of Tokyo spanning 1935 to 2025. Learn the history of the Imperial Capital through antique postcards, modern photos and cryptic clues that are randomized each time you play.
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, Mysteries of Old Tokyo takes a set of postcards printed in 1930s Tokyo from the author's collection and brings them, hand-scanned, to your personal computer in full 1024x768 resolution.
Travel to over 40 real-life Tokyo locations, based on authentic antique postcards, while solving cryptic clues and chasing down treasure for Rare Items Acquisitions (Tokyo) Ltd. You'll learn something new every time you play.
Put your research skills to the test to assemble a database of Tokyo's most famous landmarks for your mysterious employers. Then, use that data to uncover inconsistencies and arrive at the truth.
Interact with a wacky cast of wandering spirits, from the flirty Kasuga-dono to the paranoid Nakamura-san, all with their own secrets to reveal - or not.
Brand new photography from 2025, aligned and matched with the original postcards, lets you see these postcards in a modern context. Plus, learn all about each location with the original 1930s postcard description (translated for the first time from Japanese) complemented by a present-day update covering the last 90 years of Japanese history.
As an agent for Rare Item Acquisitions, you'll come to know Tokyo like the back of your hand, while managing both time and money on your quest for the treasure. Your expense account is not bottomless!
As you play, unlock new locations to visit, together with a set of stunning low-poly 3D-rendered artifacts which you can browse at your leisure in the 3D Viewer.

Its been just a week since the demo came out, but it feels like so much has happened. An idle idea I had back in April - I wonder if anyone else remembers multimedia CD-ROMs? - has turned into something people are actually playing and enjoying!
Thank you to everyone who has been in touch - Ive read every piece of feedback and it really puts a smile on my face to hear people are enjoying the demo.
Please do leave a review if you have the time, even if its short - it really helps with the Steam algorithm.
Just in time for the end of Finnish Games Week, and the start of Next Fest, Im very happy to announce the new Demo v1.2 is available with some great new features and some satisfying bug fixes.
Features
Achievements!
There are now seven Steam achievements in the game, with more to come soon. If you already played part of the demo, most should unlock automatically when you start the game. Note: If you already finished the demo and completed Week 2, getting the final achievements (week 2 and end of demo) will require you to play through one explore cycle (from meeting the spirit to seeing the Chapter Complete screen). After that a new demo complete flag is set and the achievements will be unlocked.
New menu!
With a nod to the confusing mystery meat menus of the late 90s, Ive put together a new, more visually exciting main menu with influence from classic 90s CD-ROM applications.

New type of inconsistency!
You will now need to check the spirits stories extra carefully to find if its a time violation, an impossible journey, or the new Action inconsistent with location. For example, its hard to ride a horse on the Tokyo Expressway.

The Marunouchi postcard is now part of the regular location, so spirits can appear there in Explore mode.
Changed the inconsistency generator so wont get the same type of narrative inconsistency twice except, to keep it interesting, on rare occasions you will. So read carefully!
Bug fixes
The mouse label will now reappear on Parallels Mode in the similarity finder, even if you complete one of the tabs, when you move to an incomplete tab.
Try to fix a weird bug where the fullscreen viewer appears out of nowhere if you click some wrong spot on the similarity finder.
Save button on database prep should no longer overlap the word list.
The button to open fullscreen view will no longer shrink if it is unclickable/under other controls.
Fixed the new volume slider not saving the music volume as an options file.
Fixed the new volume slider not being set visually on start-up.
Fixed a factual error regarding addressing Japanese emperors.
Other
Version number is now shown on the main menu.
The right place, wrong year logic has been adjusted to avoid choosing a location thats has a start/end date too close to the current year. For example, if a place closed in March 1955, you could argue that it was open in 1955, for a few months, which means the spirit isnt technically lying if they say they went there in 1955. To avoid this ambiguity, there is a buffer of at least 1 year between the start/end year for a location and the actual year of the story.
Added dev tools for testing report and exporting postcard data.
