'Musashi's Sword') is a Japanese sports manga series written and illustrated by Motoka Murakami that focuses on kendo.

The manga was also adapted into a Famicom platform game called Musashi no Ken – Tadaima Shugyō Chū (六三四の剣 ただいま修行中, lit.

Unfortunately, Kunihiko retired from kendo out of guilt, and Musashi then aimed to beat his son Shura Tōdō instead.

Musashi trained hard as a child under the guidance of his mother Kayo, who had retired from professional kendo and now only did her day job as a full-time grade school teacher at Musashi's school, but he also got more practice from the local dojo with Ranko Todoroki, who later became one of his closest friends.

Thanks to Kayo's words of encouragement, he made up his mind, halted his high school education, traveled from dojo to dojo and challenged their best swordsmen, just like his legendary namesake Miyamoto Musashi did (he even learned Miyamoto Musashi's double-katana technique from a reclusive old man and tailored it to suit his kendo), until he was ready to face off very strong opponents at the final national championship.

Musashi no Ken is written and illustrated by Motoka Murakami and serialized in Weekly Shōnen Sunday from April 8, 1981, to September 25, 1985.

[6][7] The individual chapters of the manga were collected into 24 tankōbon volumes published by Shogakukan between October 20, 1981, and November 18, 1985.

"Sword of Musashi - Now in the Middle of Training") is a 1986 video game developed and published by Taito exclusively in Japan.

After completing three courses, Musashi will be entered into a 2D weapon-based versus fighting-style Kendo tournament.

Anime News Network's Justin Sevakis commends the unusual realism of the anime, stating "it refuses to sugar-coat the awful, dangerous and sad aspects of life, but attacks them with a smile, a sense of humor, and a resolute strength that's incredibly inspiring."
