Luffy Herself Is Voicing Turbo Granny
Mayumi Tanaka (Monkey D. Luffy in One Piece, Krillin in Dragon Ball) voices Turbo Granny in the Dandadan TV anime, and she is keeping the role for the franchise's first stage play. According to a report from Famitsu, the long-running Japanese game and entertainment outlet, Tanaka joins Stage Dandadan: Occultic Stage as its only credited voice performer.
It is fitting casting for a character this loud. Turbo Granny is the first yokai Okarun ever runs into, the tunnel-dwelling menace who curses him and takes a very personal part of his anatomy in the manga's opening chapters. Tanaka has voiced Luffy since 1999, so the stage production is putting an instantly recognizable voice behind its most unhinged apparition.
A Trailer Shot in Real Ruins
The second PV, subtitled Kaikō-hen (roughly "the encounter"), is built on horror credentials rather than stage footage. It was directed by 川松尚良 (likely Naoyoshi Kawamatsu), a filmmaker who has handled horror direction on multiple movies, and the crew filmed at an actual ruin and an abandoned tunnel.
The footage restages the manga's opening beat. Momo believes in ghosts but not aliens; Okarun believes in aliens but not ghosts. To settle it, each ventures into the other's territory: she visits a ruined hospital known as a UFO hotspot while he walks into a haunted tunnel.
Alongside the PV, the production unveiled "apparition visuals" for its two revealed yokai. Turbo Granny gets hers with Tanaka's casting, while Acrobatic Silky, the silky-haired yokai defined by her gymnastic movement, will be played onstage by Risa Yamazaki.
The Humans of Occultic Stage
Yuiri Murayama, formerly of idol group AKB48, plays Momo (full name Momo Ayase), opposite Raimu Ninomiya as Okarun. In a fun bit of staging, 百名ヒロキ (likely Hiroki Hyakuna) performs Okarun's transformed state as a separate role. Aoi Nakabeppu as Seiko and Riko Tanaka as Aira round out the named cast. Direction comes from Imagine Ito of the dance-theater troupe Umebou, with a script by Shinjirō Kameda and music by Ryō Konishi.
The Tokyo run occupies Nippon Seinenkan Hall from August 26 through September 3, 2026, and the Osaka run follows at Sky Theater MBS from September 11 to 13. Tickets are ¥12,500 on weekdays and ¥12,800 on weekends, all seats reserved.
The production is also playing against Japanese theater etiquette: every performance ends with a special curtain call where phone photos and video are allowed and fans are encouraged to post them with the official #舞台ダンダダン hashtag. Select dates add after-talks with the creative team, cast send-offs, and a lottery for signed posters, all detailed on the play's official site. The show is part of a Japanese Agency for Cultural Affairs program for the 2026 fiscal year as well, which invites children from elementary school age through 18 for free and gives accompanying adults half-price seats.
Looking Ahead
A pre-request ticket lottery is open through July 14 on Lawson Ticket, a major Japanese ticketing service, and general sales start July 25 at 10:00 a.m. Japan time, ahead of the August 26 Tokyo premiere. No international screening or stream of the stage play has been announced.
The source material is easier to reach. Yukinobu Tatsu's manga runs on Shueisha's Shonen Jump+ app, where it has passed 14 million copies in circulation and 1 billion app views as of June 2026, and it is published in English by Viz Media and on Manga Plus. The TV anime that made Turbo Granny a menace to international viewers streams on Crunchyroll and Netflix, and a third season has been confirmed.
