Announced yesterday by the UNDERTALE MUSEUM Executive Committee, the world’s first large-scale exhibition dedicated to Toby Fox’s cult RPG is heading to Japan in 2027 — and it’s shaping up to be something Singapore fans will want to plan a trip around.

The Underground Comes to Life

UNDERTALE, the 2015 indie RPG by Toby Fox, took the world by surprise with its pixel-art world, jazz-and-chiptune soundtrack, and a combat system where mercy is always an option. A decade on, it remains one of the most beloved games of its generation — and now, for the first time ever, its underground kingdom is being built in the real world.

The exhibition concept is described as immersive rather than gallery-style: visitors won’t just look at framed artwork behind glass, but walk through spaces designed to feel like the game’s setting — from the flower-filled Ruins to the cold corridors of Snowdin. Details on specific rooms and interactive elements haven’t been released yet, but with Toby Fox overseeing the creative direction, it’s safe to expect the same care that went into every pixel of the original game.

Dates, Venues, and Where to Go

Two cities, two legs:

• Tokyo — Sunshine City Exhibition Hall A, Ikebukuro: 19 February to 10 March 2027
• Osaka — ATC Gallery: 22 April to 9 May 2027

Both venues are major exhibition spaces well-used to large-scale pop-culture events. Sunshine City in Ikebukuro is one of Tokyo’s go-to fan event halls, and the Osaka leg runs right into Golden Week (29 April – 5 May 2027) — prime travel season for Singapore visitors.

No ticket prices or booking windows have been announced yet. Follow @undertale_mus on X for updates as they drop.

Inside the Battle System — and Beyond MERCY

For the uninitiated: UNDERTALE’s core hook is a combat system where fighting is one option, but never the only one. Every encounter offers ACT, ITEM, and MERCY alongside FIGHT — and the game’s story changes depending on which path you take. It’s a premise that sounds simple and lands devastatingly well.

That emotional weight is exactly what the UNDERTALE MUSEUM promises to translate into physical space. The organising committee includes cooperation from 8-4 (the Japanese localization studio behind major Nintendo titles) and Fangamer (the official UNDERTALE merchandise partner). Both companies have deep ties to the property — and their involvement hints at a bilingual exhibition with strong international accessibility.

A Hands-On Toby Fox Production

UNDERTALE was famously made by one person. Toby Fox composed the music, wrote the script, coded the game, and drew most of the sprites — the kind of singular creative vision that rarely survives the transition to a large-scale live event. His direct supervision of the UNDERTALE MUSEUM sets this apart from licensed exhibitions that get the brand right but lose the soul. According to the official announcement (Japanese), the exhibition aims to create “a special space where determination wells up with each step forward” — which is as on-brand a promise as you’ll ever read.

For Singapore Fans: The Windows to Book Around

We covered the UNDERTALE Determination Symphony’s second Singapore night this September — but the museum is a completely different scale. For fans eyeing a Japan trip, here’s how the windows align:

• Tokyo run: 19 February – 10 March 2027. Late-February Japan can be chilly but uncrowded; cherry blossom season starts right as the exhibition closes.
• Osaka run: 22 April – 9 May 2027. Golden Week falls squarely in this window, so book accommodation early — flights and hotels fill up months in advance.

The announcement was made entirely through Japanese-language channels on 30 July 2026 and hasn’t yet been covered in English-language gaming media, so check back for updates as more details — tickets, full exhibition layout, merchandise — are confirmed. We’ll cover them here as they land.
