Mercari announced that it will hold the immersive experience event “Someone’s Favorite Room in the World” for 5 days from 28 October to 1 November 2026 at WITH HARAJUKU in Tokyo’s Harajuku district. The event recreates Japanese pop culture as the “favorite rooms” of fans overseas, offering visitors an immersive experience of how value circulates across borders.
Mercari will hold the immersive experience event “Someone’s Favorite Room in the World” at WITH HARAJUKU in Harajuku from Wednesday, 28 October to Sunday, 1 November 2026. The event will be open from 10:00 to 19:00 each day, except on the first day, when it will run from 14:30 to 19:00. Admission is free.
The event will recreate the “favorite rooms” of fictional fans from the United States, France and Taiwan. Visitors will tour rooms created based on Mercari’s cross-border transaction history, centered on Japanese pop culture-related products. Each room will reflect its resident’s profile and preferences, allowing visitors to experience that person’s world.
Each room will feature more than 1,000 items that have actually been traded across borders through Mercari. Surrounded by items that have journeyed from Japan, visitors can enjoy an immersive room tour that feels like visiting someone’s home elsewhere in the world.
As background, cross-border e-commerce transaction value is said to have reached approximately ¥4.2 trillion in 2024, amid growing interest in Japanese pop culture. Mercari has made global expansion a key pillar of its mid-term strategy, and reported global cross-border GMV of ¥11.22 billion for the fiscal year ended June 2026.
