About NASUBI

NASUBI is an indie psychological endurance game built around a very simple setup: you are naked, alone, and stuck inside an empty room. There is no food waiting for you and nobody around to talk to. The only connection to the outside world is an old rotary phone.

That sounds simple until you imagine actually being there. With nothing much to do, every phone call starts to matter. Time moves slowly, the room feels smaller, and your own thoughts become part of the problem.

A Room With Almost Nothing

The idea behind NASUBI comes from a real Japanese TV experiment from the late 1990s. Tomoaki Hamatsu, better known as Nasubi, was placed in an empty apartment and had to survive by winning prizes from mail-in sweepstakes.

He had no idea that millions of people were watching his situation on television. He eventually stayed there for 335 days.

The game takes that uncomfortable idea and turns it into a much more focused experience. There is no big world to explore. You are stuck with the room, the phone, and whatever happens next.

How To Play NASUBI

Start by taking in the room and getting used to how little you have to work with. The rotary phone is your main way of connecting with the outside, so pay attention to what happens through it.

Do not expect constant action. NASUBI is built around the uncomfortable gaps between events. Pay attention to the phone and anything that looks out of place. If something changes, you’ll want to notice.

The Real Problem Is Being Alone

What makes NASUBI unsettling is how little you can rely on. There is no busy environment to distract you and no group of characters to keep things moving. You are left with an empty room and your own thoughts.

That is also where the game's connection to the real Nasubi story becomes interesting. The original experiment was not frightening because of monsters or supernatural threats. The isolation itself was enough.

NASUBI takes that idea and puts you on the other side of the experience. The longer you stay in that room, the more you start wondering what you would actually do if there were nowhere else to go.
