Inokashira Park (井の頭恩賜公園, Inokashira Onshi Kōen)? is based on the real location in Tokyo, Japan. The famous Inokashira Pond is the only visible part of that area. Its full name Inokashira Onshi Kōen translates to "Inokashira Imperial Grant Park" in English.
Inokashira Park is one of the hangout locations available in the Tokyo map. It is unlocked after Ann Takamaki's Confidant has reached Rank 3, or if the protagonist reads the Weekend Parks book. If Munehisa Iwai is invited to this location, he gifts the protagonist with a Swan Boat figure that can be displayed on his shelf in the attic in Leblanc.
Persona 5 Royal
Principal Kobayakawa organizes a clean up effort of Inokashira Park scheduled for May 30th. Many students, including Ryuji, believe it to be a PR stunt to protect Shujin Academy's reputation after Kamoshida's change of heart, and consider the entire activity to be boring. This event is also where the Faith Confidant with Kasumi Yoshizawa is automatically established.
