Toby Fox Comments on Undertale Museum Role as Supervisor
Fox's own account of his involvement, and the specific February and April 2027 run dates, are the two real signals here: an exhibition planned a year and a half out, with the creator offering suggestions rather than serving as its designer.

Undertale Museum released a new comment from creator Toby Fox on September 30. Fox says the original proposal lacked the silly elements he wanted, so he made several small suggestions to bring it closer to Undertale. He describes his credited role as supervisor as adding a final pass to proposals from FUNDOM. Tokyo dates are February 19 to March 10, 2027, at Ikebukuro Sunshine City; Osaka runs April 22 to May 9, 2027.
In the comment, Fox says the proposals he reviewed did not initially include the silly ideas he associates with the game, so he offered several small suggestions to push the material in that direction. He also addresses his credited title directly, saying his role amounts to a final pass on what FUNDOM brought him rather than direction of the exhibition's content.
The event's Tokyo dates are February 19 to March 10, 2027, at Ikebukuro Sunshine City Exhibition Hall A in Toshima ward, running 10:00 to 19:00. Osaka follows from April 22 to May 9, 2027, at Osaka Nanko ATC Gallery, with hours still to be announced. Advance admission is 2,500 yen for general visitors and 2,000 yen for elementary students; ticket-with-goods tiers are 5,500 yen and 5,000 yen. Preschool children enter free. The full comment text is on the official X account and the event website.
