A Japanese duo consisting of singing samurai Kumagai Tatsuro and keyboard ninja ichi.

With the desire to "spread the greatness of Japanese songs to the world," they will be making their full-scale debut in 2024.

Focusing mainly on covers, their songs are slow, gentle and piercing to the soul, and their live performance skills, which get the crowd excited to a level that's hard to believe they're a duo, are like ninja arts.

Taking on the world with singing, piano and Japanese spirit.

A Japanese duo with Uta Samurai Kumagai Tatsurou and Kenban Ninja Ichi.

We started in 2024 to share the beauty of Japanese songs with the world.

We captivate audiences with delicate and emotional performances featuring heart-piercing songs,

and our live shows bring an energy that feels like magic—far beyond what you'd expect from a duo, just like ninja arts.

With songs, piano, and the spirit of Yamato, we bring them to the world.
