The group had been composed of 8 members, Mizuki Yamaguchi, Haruka Momokawa, Mai Ishioka, Miho Kaneno, Ayanami Tanigaki, Yuki Yamanaka, Shiori Tatsumi, and Erika Matsushita, but in November 2012, two members, Yuriaki Tama and Renno Kinoshita, joined the group and will focus on supporting "fishery industry". In May 2013, six new members joined the group: Yuria Yukino, Saki Shimizu, Mirai Tachibana, Koharu Nanami, Erika Moriyama, and Mariho Yokoha. The new team will be divided into two teams, Junjo Tropical Maru and Seishun Tropical Maru, and will begin regular weekly performances.

The coupling song is an original song of Junjo Tropical Maru (or Seishun Tropical Maru's original song) "Undecided", which is sung at their regular weekly performances.
