Sayumi Michishige
This single marks the debut of the "sixth generation" members Miki Fujimoto (who came from a Hello! Project solo career), Sayumi Michishige, Eri Kamei and Reina Tanaka. Once the sixth generation joined, it made it the group's biggest formation yet, with 15 members. Like "Do It! Now" and "As for One Day", "Shabondama" was used as an image song for Quidam, a Cirque du Soleil show. It was released in two editions, a regular and a limited edition coming with fifteen photocards and comes in special packaging.
