YOHAKU

Games and small tools, made in Tokyo.

YOHAKU is a one-person studio. It makes small games, tools that turn a plan or a letter into something you can send, and itineraries you edit on your phone.

余白yohaku: the space you leave on purpose.

A loop of elevated road at night, lit by a row of orange lamps, with one car and its headlights

Night Loop 夜の環状線

A one-button race on an elevated loop at night. Hold to accelerate, let go to brake. Take a curve too fast and you hit the wall. Three laps, against your own best.

Playable here soon.

Itineraries for your phone

Type the plan on your phone and send it to the group chat as images. No Canva, no app. One edition for each occasion, with its own cover and colours.

Tools 道具

Three free tools, each for a different thing you hand to someone.

Three pages of a trip itinerary: cover, schedule, packing and notes

Shiori 旅のしおり

A trip plan, typeset as a paper itinerary. Type the dates, the schedule, what to bring and what it costs, and the pages lay themselves out as you go. Save them as images and send them to the group. Free, in English and Japanese.

A sealed envelope and a letter set in vertical Japanese

Fumi 文

A letter in vertical Japanese, sent as two images. Send the envelope first and the letter second, so it opens the way a real one does. Free, in Japanese.

A binder of illustrated cards, each a moment from daily life

Encounters 遭遇図鑑

A card collection of the things you run into. Make a card from a photo and a line, and it is rated by how many times it happens in a life: the morning commute is common, a once-only scene is not. In Japanese.

The studio 余白

One person in Tokyo, with a background in fine art and in building business systems. The studio makes small games, and things for the moment you hand something over: the plan before a trip, a letter that is too much for a chat bubble.

Everything is made for the phone first: one press to play, one tap to send.
