Background of Introduction Jiyugaoka Hikari-gai is a shopping arcade-style shopping street in Jiyugaoka, Tokyo. While it has a history dating back to the post-war period and a retro atmosphere with unique specialty stores, it experienced a period where 10 out of 46 stores were vacant after the COVID-19 pandemic.
