<Matsuken Mamire Mamire Island Summer Battle Project Overview>

In collaboration with Matsuken and Yokohama Hakkeijima Sea Paradise, the "Matsuken Mamire Amusement Park," which was a hot topic and very crowded in the spring, will evolve into "Matsuken Mamire Mamire Amusement Park" with new attractions this summer, in response to many requests to "keep it open for a longer period." Furthermore, to blow away the summer heat with laughter, the "Matsuken Mamire Mamire Aquarium" will be added, expanding the "mamire" experience by approximately double. The "Matsuken Mamire Mamire Island Summer Battle" will unfold, with Hakkeijima entirely dominated by Matsuken.

This project will create an extreme world view of "Matsuken everywhere, Matsuken Samba no matter what you do." Guests will experience an "excessively immersive entertainment space" where they are enveloped by Matsuken visually, audibly, and experientially from the moment they step in. Numerous mechanisms are in place to increase the "Matsuken concentration" the more you participate, realizing an abnormal immersive experience where you "can't escape Matsuken all day long." It is a theme park dominated by Matsuken at an unprecedented level, blending laughter and bewilderment.
