P-144 opened in Papillon Bldg. near the east exit of Ikebukuro Station on March 1, 2023. This new community hub is a joint project of Sunshine City Corporation and good mornings Co., Ltd. The “P” in P-144 is short for Papillon while the “-144” is derived from the address (Higashi-Ikebukuro 1-4-4). Prior to opening, the top two floors of the 5-story building were removed to reduce environmental impact and improve earthquake resistance. The renovated 60-year-old building is now 3 stories tall.
