MAPA to Release First Single With New Lineup: “Ame no Shiro / KESHI♡GOMU♡MAGIC”

MAPA, the six-member idol group led by Megumi Koshoji (formerly of Maison book girl and BiS), will release their 7th single “Ame no Shiro / KESHI♡GOMU♡MAGIC” on Wednesday, June 18, 2025.
As with previous releases, the single is produced and written by singer-songwriter Seiko Omori, with arrangement by sugarbeans. This marks MAPA’s first single since welcoming new members, showcasing a refreshed sound and spirit.
The record features Seiko Omori’s signature raw and emotionally stirring lyrics, paired with sugarbeans’ bold, forward-looking arrangements—designed specifically to push MAPA into their “next stage.” The music was recorded with a full live band: Hiroomi Shitara (guitar), Manabu Chigasaki (bass), Tomohiro Harigae (drums), sugarbeans (piano), and Omori herself on chorus.
To celebrate the release, MAPA will embark on a six-city “Ame no Shiro Tour”, their first tour with the new six-member formation.
MAPA is also set to perform in London this June as part of WACK in the U.K. Vol. 6.
■ Comment from Seiko Omori
“MAPA is a group that values the little distortions found in everyday life, so many of our songs are tied to the seasons. Since this release comes during Japan’s rainy season, I created a song around the theme of a ‘Rain Castle.’
While we often imagine girls living in fairytale castles overseas, I hope you’ll find beauty in the image of a girl in a Japanese castle, donning armor and defending her heart in solitude.”
■ Comment from Megumi Koshoji
“I love listening to music on rainy days.
I hope our ‘Rain Castle’ becomes a song that gives strength to those who are fighting their own battles this June.
We’re also launching our first nationwide tour as a six-member group. I’m already excited about putting together a live setlist that includes the new songs.
We hope you’ll visit MAPA’s castle—whether it’s your first time or your first in a while—as the seasons shift around us.”
