Six Touken Danshi Step Up as Fitness Instructors in Fit Boxing 刀剣乱舞 -出陣！えくささいず本丸-

Imagineer has officially announced Fit Boxing 刀剣乱舞 -出陣！えくささいず本丸- (Fit Boxing Touken Ranbu: Sortie! Exercise Honmaru), a collaboration between the massively popular Touken Ranbu ONLINE and the Fit Boxing exercise game series. The title is scheduled to launch on January 15, 2027 for Nintendo Switch and Nintendo Switch 2. Pre-orders for the physical edition — including a deluxe limited box — opened on September 10.

About the Two Franchises

Touken Ranbu ONLINE is a sword-raising simulation game that has surpassed 15 million registered users. Players take on the role of a “Saniwa” who commands the “Touken Danshi” — legendary swords reborn as warriors — across eight weapon types: tantō, wakizashi, uchigatana, tachi, ōdachi, naginata, yari, and ken.

The Fit Boxing series is a rhythm-based boxing exercise game for Nintendo Switch that uses Joy-Con™ controllers, with popular voice actors voicing in-game instructors. Since its debut in December 2018 as the first exercise game on Nintendo Switch, the series has sold over 3.5 million copies worldwide.

Six Instructors, One Honmaru

The collaboration retains all the core mechanics of Fit Boxing while introducing six Touken Danshi as personal instructors:

• Mikazuki Munechika (三日月宗近)
• Ōkanehira (大包平)
• Shokudaikiri Mitsutada (燭台切光忠)
• Heshikiri Hasebe (へし切長谷部)
• Yamabakiri Nagayoshi (山姥切長義)
• Kumonō (雲生)

Each instructor will guide the player — addressed as “Master” — through daily workouts, alternating between encouragement and firm coaching depending on their personality.

Game Modes and New Features

The game includes the series’ staple Daily mode, where instructors automatically build a workout plan based on the player’s goals and condition, and Free mode, which lets players pick their own routines. Both solo and two-player co-op are supported. A Lecture mode covers basic exercise posture and punching technique, making the game accessible to Fit Boxing newcomers.

A brand-new addition to the series is Nitou Kenbu (二刀拳舞) mode, which lets players choose two Touken Danshi as a main and sub instructor simultaneously. The duo delivers alternating coaching cues and banter between exercises, offering a fresh experience unlike anything in previous Fit Boxing titles.

Completing workouts raises the Musubi (結び) bond level with each Touken Danshi, unlocking new dialogue and story episodes exclusive to this game.

Music and Content

The game features 30 BGM tracks — 10 original Fit Boxing compositions and 20 arranged tracks from Touken Ranbu ONLINE. Exercise content includes standard routines, stretching, and the fan-favourite Saniwa Health Exercise (さにわ健康体操) from the Touken Ranbu universe. Series staples such as a stamp calendar, punch-count and calorie-burn tracking, and over 250 achievements are also present, all dressed in Touken Ranbu-themed visuals.
