Mercari will hold “My Family Home: Bringing Everyone’s “Welcome Home” Back Once Again,” an immersive event in Harajuku where visitors can discover the value of unwanted items stored at their parents’ homes and experience listing them, ahead of year-end cleaning and the season for returning home for the holidays. The event will feature a recreation of a room filled with Heisei-era memories, an AI listing experience and a range of other content.
Mercari will open the four-day immersive event “My Family Home: Bringing Everyone’s “Welcome Home” Back Once Again” in Harajuku, Tokyo, from 26 November 2026 (Thursday) to 29 November 2026 (Sunday). The venue is GATE (formerly UNKNOWN HARAJUKU), and admission is free.
The event will display approximately 1,000 nostalgic items in a recreation of a “children’s room” filled with Heisei-era memories. Visitors will have the opportunity to learn about the value of items from the Showa and Heisei eras and experience current trends in flea-market transaction prices.
The venue will recreate family life through features including cast members dressed as fathers and mothers greeting visitors, family photo sessions and an “Mom Reminder” that visitors can enjoy even before arriving. An area where visitors can try Mercari’s AI listing feature will also be available, allowing them to experience a tool designed to reduce the burden of listing items.
The event was planned as an initiative to address the issue of personal belongings remaining at parents’ homes and the difficulty of listing them, based on the 2025 survey of “hidden assets” stored in Japanese households. It also presents points of interest from multiple perspectives, including a dedicated website, campaigns and comments from advisers.
