The Hamutsun Serve (はむつんサーブ) is a Japanese dance unit made up of 2 members, Rikiccho and Dah-yoshi.

Formed in 1999 by students of Fukushima University, they gained reputation as performers of 'Animation Dance' through TV appearances in Japan. They have appeared in " 4 Minutes" video, as Madonna had previously noticed their performance on YouTube. Most recently, Rikiccho and Dah-Yoshi have collaborated with Madonna for her 2008 Sticky & Sweet Tour: they made appearances during the " Rain" interlude (which was mashed with the Eurythmics' " Here Comes The Rain Again"), "Devil Wouldn't Recognize You", " Ray of Light" and briefly during the bridge of " Hung Up".
