Our dedicated team manages the entire process from initial inquiry to final delivery. This specialized support is particularly valuable for events utilizing “Smart Tickets,” which often require specific mobile app setups and Japanese phone number authentication. By handling these logistics on your behalf, we provide a reliable path to your favorite shows while offering flexible payment options that suit your travel needs.
Jasumo offers a specialized facilitation service for foreign tourists and non-Japanese residents in Japan, assisting with ticket acquisition for cultural and entertainment events through authorized and official platforms. We are not a ticket reseller and do not sell tickets directly. Our role is to guide international customers through the official booking process and help overcome common challenges, including:
What documents do I need to enter with an UNDER 18 ticket?
Attendees with a U18 ticket must present a valid form of identification that verifies their age, such as a student ID, health insurance card, or passport. If you fail to provide proof of age at the entrance, you will be required to pay the difference for a general admission ticket.
Are there refunds available if a specific artist on the lineup cancels?
No refunds will be issued due to changes or cancellations in the performing artist lineup, nor for personal circumstances of the ticket holder. The festival proceeds as planned across multiple stages, and the ticket covers entry to the event as a whole rather than a specific artist.
How many children can I bring for free under the elementary school age policy?
Children under elementary school age are admitted free of charge, but this is limited to one child per accompanying adult. Any additional children or those in elementary school and above will require their own valid ticket for entry.
What is the entry process once I arrive at the Yokohama Red Brick Warehouse?
Physical or digital tickets will be exchanged for a festival wristband at the designated exchange booths near the entrance. You must wear this wristband at all times to access the different stages and re-enter the festival grounds throughout the day.
Is it possible to receive my festival ticket digitally on my phone?
Yes, if you apply via a smartphone, you can choose to receive a “Smart Ticket,” which is a digital pass stored on your device. This method allows for a seamless, paperless entry and reduces the risk of losing physical tickets during your trip to Yokohama.
