Boso-sai
房走祭
Premium automotive festival showcasing rare classic cars and latest vehicles alongside hypercar demonstrations at an exclusive Mount Fuji venue.

Boso-sai, a premium festival celebrating automotive culture, will take place on December 6 and 7. Hosted at the exclusive THE MAGARIGAWA CLUB, the event promises two days of exhilarating experiences designed to engage all five senses: “Drive it. See it. Feel it!”
Nestled in a breathtaking location with views of Mount Fuji and Tokyo Bay, THE MAGARIGAWA CLUB features a 3.5 km driving course, a clubhouse blending tradition and modernity, a restaurant, spa facilities, and an infinity pool - all wrapped in an Asian-luxury atmosphere. For this year's Boso-sai, rare classic cars and the latest vehicles from partner manufacturers will take to the course under special themes, offering visitors an immersive encounter with automotive history and the future.
The festival will host legendary motorsports figures, including Kamui Kobayashi, alongside pro-driver demonstrations of some of the world’s most elite hypercars, such as the Mercedes-AMG ONE, Aston Martin Valkyrie, and Ferrari Monza SP1/SP2/Daytona SP3. Audiences can witness these ultimate machines navigating the course with breathtaking speed and precision - a spectacle not to be missed.
While THE MAGARIGAWA CLUB is usually a members-only facility, Boso-sai will open its doors to the general public. The event’s highlights include driving demonstrations, exhibitions, workshops, stage events, merchandise sales, and the “Creators’ Market,” where fans can purchase music and automotive-related items directly from producers. The theme of the event is a dynamic, sensory-rich celebration of the power and beauty of engines and the emotional impact of driving, combined with gourmet cuisine, music, and camaraderie.
