About
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.
You’re a historian now! 30 hand-crafted puzzles explore the fascinating history of the Imperial Capital. Each week, you'll explore three new locations based on a 1930s postcard:
Take a photo to show the present day view at the very same spot.
Collect evidence linked to the site: books, magazines, maps, paintings, archive photos, and more.
Use analysis and synthesis to build the complete picture from multiple sources, just like a real historian.
Extract words to correct the historical record in "fill-in-the-gap"-style gameplay.
Why did the Forty-Seven Ronin kill [ ]?
Why is [ ] vital to the spiritual defence of the entire city?
What became of the Three Human [ ]?
Analyse your photos to compare the changes between the 1930s to the 2020s.
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.
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.
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.
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.
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.
Each postcard is complemented by the original description, human-translated from Japanese for the first time. Illustrations, modern-day photographs, and an author's commentary provide the full picture.
From Akabane to Zoshigaya: Ride the rails on a meticulous recreation of 18 real-world train lines and over a hundred stations in Tokyo.
Go back in time with a complex four-dimensional map of Tokyo's transit, covering every year from 1872 right up to the present day.
Hundreds more Tokyo locations in the landmark database, visited by mysterious spirits, from the Imperial Hotel to the Tokyo Skytree.
A huge encyclopedia based on extensive research, telling the whole story of Tokyo from prehistory, through the Edo period, to the 80s bubble and beyond.
Ancient fortresses crumble. Long-forgotten spirits flood the city. A powerful supernatural force threatens to upend the everyday lives of Tokyo’s 14 million residents.

An edutainment style game that once in a while gives you the impression it is more than that. I want to give a big disclaimer that this game is precisely what it claims to be and not much more. In this age with meta narratives, subvertion of expectations and various twists. It is easy to be fooled that we are building towards a narrative payoff. In this case temper your expectations and realize. Just learning about stuff is worthwhile on its own. You are given postcards and are asked to fill in the blanks of various trivia related to them. While doing so you will travel around Tokyo using a strikingly accurate simulation of the Tokyo train lines. Once in a while you will do ace attorney style interrogations where you are tested on your knowledge. To me it is a similar satisfaction as solving a weekly crossword puzzle. The format of the game is paced across multiple weeks where you explore various parts and eras of Tokyo. The game is at its strongest when it presents an compelling story and asks you to draw conclusions to fill in the trivia. It is at its weakest when the trivia you are asked to fill in is either. An excessive box of blank spaces where if you speak English as a second language you will struggle. Asking you to recall obscure details, or asking you to basically just orient yourself with the cardinal directions on a photo. that said the good outweighs the bad. If this appeals to you at all. This is all there is to the game. Buy it. You will enjoy it. I did. Don't overthink it. If this game is appealing to you. Just buy it.

I wanted to write a review for this because this kind of game is just up my alley - I really enjoy history, and I find Japan especially interesting, for whatever reason. The good, the bad, the in between; Japan's history fascinates me, and this game handles that aspect of things incredibly well. It's researched and presented with care, showing Japan as the complex place it really is and treating it with dignity without putting it up on a pedestal. The story was well-rendered and thoughtful, and Tenjin was an interesting accidental antagonist. Visually creepy, but just as thoughtful as I would expect a god of learning to be. The quirky, retro-inspired style of the game fits in well with the wave of more recent internet-inspired horror without feeling derivative and suiting the direction and setting of the game. I could feel the inspiration of various things while playing this, and while the puzzles were tricky at times only one actually required me to look up any assistance (the airplane one) and that was only down to the fact that I have very poor spatial awareness. It's also set up well enough that you can use grammar as an additional assistance tool to figure out what fits the blanks, if you really need that extra little boost. The ghosts were also fun, and I'm looking forward to learning the rest of their stories in the post game. And of course, the music was very snazzy and easy on the ears. My only complaint? The postcards mean that the Shinsengumi's few Tokyo-related monuments were doomed to never appear in-game. Alas.
That's the kind of history lesson in needed in my life! This game is sooo cool and the 90s aesthetic and the fact that it's based on real postcards makes it even better. I also very much appreciate the inclusion of the original Japanese texts and the links to Tokyo Metropolitan Library's website. There's some kind of eerie undertone with all the supernatural activity going on, but the game always manages to stay chill. It's gave me all the time I needed for exploring in my own pace, while keeping that mysterious atmosphere. Above me, the Sky God mocking me for my bad sense of direction. It would be interesting to have an additional "harder" game mode, where taking the shortest route or avoiding mistakes actually mattered. I've never been into history all that much, but Mysteries of Old Tokyo really managed to captivate me. Would love to see similar games set in different parts of Japan or even other parts of the world!
A classic edutainment program. Really could have lived on some classroom PC in the past. The tried and tested fill-in-the-blanks data entry and database browsing portions of each day are the heart of [i]Mysteries of Old Tokyo[/i] and the most developed. You have to dig through files, discern information, sometimes convert units, all on your own. These sections were great, and so were the optional "Spirit Reports", which force you to dive even deeper into the material. In other sections a certain "debut-ness" became apparent, where a game developer hasn't learned yet to OPTIMIZE every bit for FUN. For instance, I was surprised the postcards weren't used in more interesting ways. Finding the "parallels" between present and past mostly seemed trivial, small details in the main postcards rarely mattered. The data gathering (where you are out and about), too, could do with some tweaks: Currently you're picking a destination and the PDA marquee text will guide you step by step: Walk to this station, now use this train line, then change tracks... Sure, I could simply not look at the help text, but it wasn't framed as a hint mechanic, so I simply followed the directions, which was not super engaging. Maybe one could incentivize the successful memorization of each journey? In the 90s, if you were planning to head to an unknown destination, prep work was essential: Once you were out and OFFLINE, your A4 printouts were all you had. No GPS. No way to easily look things up on your phone while on the go. And you often noticed that the ideal route you had planned at home didn't quite match up with the reality of being outside.
Really enjoyed this! I love historical research, and Mysteries of Old Toyko gamifies it in a fun and satisfying way. I knew basically nothing about Tokyo's history going in, but I learned a ton through this game. Having to hunt for and verify facts myself was a very engaging way to learn, and I appreciated the author's commentary on the propaganda angle of the postcards that appear to have inspired the game. I'll definitely be keeping an eye out for future games from this developer!
Unique, fun, stylin retroeducation game
( full review with screenshots: https://gaming-parrot.com/post/mysteries-of-old-tokyo-review-the-more-you-know/ ) Mysteries of Old Tokyo is a good game made of a bunch of parts that don't necessarily combine well. It is ostensibly a mystery puzzle game in which you use a 90's computer interface to navigate around Tokyo, find documents, and then use information from those documents to complete reports about the locations you visited. That said, the mystery element is really barely there and the puzzles are generally very easy. It's best approached as an edutainment game for people who want to learn about some lesser-known parts of Tokyo. Luckily, that's fine for me. Mysteries of Old Tokyo takes place over 11 weeks, with each one tasking you with going to about three thematically linked locations. You always start from the Marunouchi Building next to Tokyo station, and you can use your handy PDA to plot a route on the train system to each of your assigned locations in turn. Once you arrive, you'll get a couple of short documents about the place, possibly be assigned a new place, possibly meet a spirit, and then need to take a photo. Confusingly, despite the retro interface, all the photos, train network, and documents all make it clear that the game is set in 2025. Once you've done that at all locations for the week, it's time to return to the office. You'll then need to match a few locations in your photographs to pieces of postcards of the same area about 100 years ago and fill in 5-10 blank spots in reports about the area with words from a word bank. This is the puzzle part of the game, but you should know that these are usually very easy. At least two of the blank spots are usually just the name of the location you're looking at, and even when the answers aren't completely obvious, there just aren't enough combinations for it to ever be very difficult. Thankfully, while it's not the greatest puzzle ever, the reports you unlock on the location afterward are genuinely interesting and full of fun trivia. Finally, there are those spirits you may have talked to. After you're done with your main report, you can optionally complete a spirit report, where you'll be presented with everything the spirit said and asked to determine the year its story was set and which of its 5-10 statements was a lie. I think these could be a good bit more challenging as puzzles if you're not very familiar with Tokyo, but if you are, a lot of the lies involve travel times or stations that you'll immediately recognize as impossible even before you have all the clues. The stories also reuse dates a lot, so once you know when the Great Kanto Earthquake or Ii Naosuke's assassination happened, that piece of future reports is basically free. Still, the writing comes to the rescue again. Even if these aren't amazing as puzzles, the stories you unlock for completing them are worth the small effort. Once you accept that this is really an edutainment game, you can appreciate a lot of otherwise pointless optional details scattered throughout. There are postcards with writeups and trivia for about a dozen locations you don't actually need to visit. There are 3D models with detailed articles about a similar number of pieces of technology you can buy with money you save from being efficient with your travel. Not only is the train network fully modeled, there's even a tool you can use to view its status in any year from 1860 to 2025 and plot a route between any two stations or postcards in any year. The postcards are from a real set someone made and include the original Japanese text alongside a translation. You can tell this was a labor of love.
Surprisingly fun and interesting game.
As someone who likes Obra Dinn (likes), history and Japan, this game was a delight! It was especially fun for me to recognize certain landmarks that I raw when I visited Tokyo years ago. Other things I liked was the nostalgic aspect of 90s esque gameplay and visuals, good old fashioned edutainment feel! I hope there'll be more games likes this in the future :D
I enjoyed it overall! It's a bit hard to classify. It's a mix of exploration, cross referencing, and Ace Attorney style statement disproving. It's not super challenging, but has a nice flow of things to discover.
