Mount Fuji, the eighth station. Three thousand metres up, three days before the mountain closes for the year. A small hut called Kumokiri. That is all of it.

Tonight there are three people staying. Three, and one more. Kyoichiro Hayami, forty-seven, a mountain photographer. Twenty-five years ago he photographed the dawn from above this hut, and that one picture made his name. He has come back on the same date every year since.

Next month a book collects all twenty-five years of it. He has written the afterword, and tonight he means to let the other three read it.

At 22:40 a thunderstorm settles on the eighth station. The trail closes above and below. The call is made. But no rescue team can move until the sun is up.

At 03:00 he is found dead on the rocks, twenty metres below the camera platform.

The wind is over twenty metres a second. Nobody heard anything.

First light is at 05:12. The rescue team is due at 06:30. Until then, there are three of you in this hut.

There is no vote in this game

In most murder mysteries everyone votes at the end to name the killer. Not here. Here you decide whose camera takes the last photograph.

• The tripod survived. There are three cameras in the hut, and before 05:12 there is time for exactly one frame
• The three of you talk and choose one camera
• Whoever presses the shutter is the one who tells the rescue team about tonight
• Which camera you choose decides what survives of the story — three endings, all of them real

If 05:12 arrives with no agreement, nobody takes the picture. The tripod stands there and morning comes. That is not a failure. It is one of the proper endings.

This is not an ending where you catch a killer. You can name the killer or fail to; the story finishes either way. What you are deciding is which version of a twenty-five-year-old night reaches the world.

The motive points the wrong way

Every table starts in the same place: somebody wanted the afterword stopped, so they killed him.

All of that is wrong, and the game is built so that you find out why. The person who wanted it stopped already had the power to stop it — and his death is the worst thing that could have happened to them.

He was not killed to bury something. He was killed to get it published.

How it plays

Every piece of evidence in this game is a record — an arrivals log that stops at half past nine, an equipment checklist where one line carries a tick and no date, a photographer’s notebook, an accident report from twenty-five years ago, a call log with three calls that never connected. Twelve items in all. There is no artwork to look at and nothing to assemble. It is built to work with text alone, which is also why it plays as well over voice chat as it does around a table.

The two numbers that decide everything are three hours apart. The hut’s wind gauge reads 21.4 metres a second at two in the morning, and 6.8 at five. The hut’s own booklet says not to go outside above fifteen.

One person hosts. The host runs the game and does not solve it — that is standard for Japanese-style murder mystery, and it is what lets the story hold things back the way it does. Every line the host reads aloud is written out, in order, in the Host Script. About 20 minutes of prep.

At three players nobody sits out, and none of the three goals is “name the killer”. One of you wants to find out what her brother actually did on a night twenty-five years ago. One wants a book published without being suspected. One wants to decide the fate of a manuscript under her own name.

You do not need to know anything about Japan or about mountains. Six words are load-bearing and Read Me First explains all six on one page. One custom appears — goraiko, the sunrise worshipped from a summit — and the host reads the explanation aloud before it matters. You will not need it to solve the game, but it changes what the ending means.

Suggested running order (90–120 minutes): opening and reading 20 / introductions 10 / discussion 20 / investigation 25 / mid-game reveal 5 / discussion 25 / the last frame 15 / solution 15.

Before you download

• 1 host + 3 players. Four people total. The host does not play
• Single use. Once you know the solution you cannot play it again
• Deals with a death in the mountains and a fatal accident twenty-five years ago. One character is the sibling of the person who died back then
• Tonight’s death is a fall. No gore, no injury and no violence are described
• Nothing in this game depicts self-harm
• Digital download — no physical item ships
• English edition. Originally written and published in Japanese

Mount Fuji is a real mountain, but Kumokiri Hut is invented, and so are the publisher, the photographer, the book and every record shown in the game. No real mountain hut, alpine club, rescue service, organisation or person appears in it. Every wind speed and time exists for the story and is not a guide to climbing anything.

About us

Ai-Q Labs is a small studio in Japan. We write murder mystery in the Japanese style — マーダーミステリー, the format that fills game cafes in Tokyo, where the host runs the table and never solves it.

Every title in this series is written in Japanese first and then rewritten in English, and every clue is a document — there is no artwork to look at and nothing to assemble, which is why it plays as well over voice chat as it does around a table.
