If you’ve ever wanted to see Miyamoto Musashi, Honda Tadakatsu, and a whole roster of Japan’s greatest historical fighters settle things once and for all in an anime — this one’s for you. Tenkaichi: The Greatest Warrior Under the Rising Sun (テンカイチ 日本最強武芸者決定戦) is officially getting a TV anime, premiering in April 2027, and the first teaser PV and cast are out now.
What Is Tenkaichi?
The manga, written by Yōsuke Nakamaru and illustrated by Kyōtarō Azuma, launched in Kodansha’s Monthly Young Magazine in January 2021 and has been running ever since — 14 volumes in as of August 2026. The premise is deliciously simple: the year is 1600, Oda Nobunaga has unified Japan and is getting old, and rather than naming an heir, he announces a tournament. Whoever brings him the strongest warrior in the land wins control of the country.
The result is a single-elimination martial arts bracket — anything goes, death is on the table — pitting Japan’s legendary fighters against each other in match-ups that history never gave us. First up: undefeated prodigy Miyamoto Musashi (sponsored by the Chōsokabe clan) versus peerless spear-wielder Honda Tadakatsu (sponsored by Tokugawa Ieyasu). If you love Vinland Saga or Rurouni Kenshin, Tenkaichi occupies a similar space: real historical figures, deeply fictional fights, spectacular violence. The manga is available in English on Kodansha’s K Manga platform if you want to start reading before April 2027 rolls around.
The Warriors Assemble — Cast and Staff
The teaser PV dropped on August 13, 2026 alongside the key visual and the first cast reveals, as reported by Anime News Network. Studio Fugaku is producing the animation with Masashi Abe directing, Kazuharu Sato handling series composition, and Hayato Matsuo composing the music. Character designs are by Ryōji Nakamori.
The three cast members announced so far:
- Miyamoto Musashi — voiced by Gen Sato
- Honda Tadakatsu — voiced by Kenichiro Matsuda
- Oda Nobunaga — voiced by Kenyu Horiuchi
Watch the Teaser PV
The teaser is largely mood and atmosphere — Nobunaga declaring the tournament, brief glimpses of the combatants, and enough of Musashi’s wooden-sword style to get your blood pumping. It establishes that this is going to be a brutal, high-stakes affair.
Read the Manga Before April 2027
14 volumes is a manageable catch-up — and volume 14 ships on August 20, so there’s never been a better moment to dive in. Tenkaichi is published in English digitally on K Manga, Kodansha’s official digital platform, which Singapore readers can access. If you enjoy historical action manga in the vein of Vagabond or the bonkers spectacle of Record of Ragnarok, Tenkaichi sits somewhere in between: historically grounded character identities with full creative licence on the fights.

When and Where to Watch
The anime premieres in April 2027 in Japan. Streaming rights for Singapore and the broader Southeast Asia region have not been announced yet — watch the official Tenkaichi anime website for updates. Given Kodansha’s existing relationships with Crunchyroll for other titles, an international simulcast is possible, but nothing is confirmed. We’ll update when streaming details land.
