The Yamanashi Nouveau Wine Festival is an annual event to promote Japan’s premier viticultural region. The festival centers on the seasonal release of “nouveau” wines, specifically highlighting indigenous varieties such as Koshu and Muscat Bailey A. Visitors have the opportunity to sample and purchase over 60 different labels from approximately 40 producers, providing a comprehensive overview of the current season’s yield in a central outdoor setting.

It is highly recommended to purchase tickets online in advance, as they typically include a commemorative tasting glass and vouchers that may sell out before the event begins. Arriving at the opening time is advised to avoid long queues at the most popular producer booths. Many attendees bring picnic mats to enjoy their wine on the Hibiya Park lawns, creating a social, relaxed atmosphere. The venue is easily accessible via Hibiya or Kasumigaseki stations.
