The fan event for the stage play Uramichi Oniisan — officially titled “Autumn Exercise! Let’s Hold a Sports Festival with All the Good Kids! A.K.A. 【Grand Sports Festival!!!】” — took place on November 7 at Furusato Gekijō in Kawasaki City Civic Plaza, Kanagawa Prefecture. During the event, it was announced that a second stage production will be performed in early July 2027.

About Uramichi Oniisan

Uramichi Oniisan is a manga by Gaku Kuze, published by Ichijinsha. The series is a dark comedy following the very adult, very relatable daily life of Uramichi Omota — a gymnastics instructor on a children’s TV program who can’t quite keep his bleak inner thoughts from slipping out on air.

Cast in Attendance

The event brought together the cast from the first stage production, which ran in July, including:

• Ryuto Nishiumi — Uramichi Omota
• Kokoro Nikaido — Iketeru Jaga
• Ryota Nakata — Tobikichi Usahara
• Maria Sawada — Shino Tadano
• Takuki Taguchi — Yorito Dekida
• Koren Shimada — Eddie Edadoro
• Ryosuke Ogura — Hambei Kizumi
• Shuto Washio — Matahiko Nekota

Shoichiro Omi (Mitsuo Kumagai) and Noritaka Nakajima (Saito Kamitake) also appeared via video during the mini-game segment.

Event Highlights

Held across three performances, the event was framed as a live recording of the in-universe children’s TV show Maman to Together. Audience members participated as “good kids,” divided into Red and White teams to compete in various activities alongside the cast.

The event opened with the signature greeting from Maman to Together, followed by a Radio Calisthenics warm-up that the seated audience joined in on. The athlete’s oath — delivered by Uramichi and his co-host — pledged to compete in the spirit of sportsmanship, but only “to the extent that it won’t affect us the next day,” a perfectly on-brand twist for the series.

The first competition, “Let’s Carry Usao-kun and Kumao-kun! Relay Race!”, had audience members pass plush toys hand-to-hand as fast as possible. This was followed by a borrowing race in which cast members searched the audience for items matching given prompts.

Mid-event, the in-universe recording was paused and the cast stepped out of character for a mini-game segment, including a Call & Response volume battle between the two teams.

Once back in character, the final competition — a ball-toss game where audience members threw paper balloons into boxes held by the cast — brought the athletic program to a close. The event ended with everyone performing the “ABC Taisō” exercise routine together.

Final results: Red team won in the first performance; White team took victory in both the second and third performances.
