How does the 2-day pass work compared to one-day tickets?

The 2-day pass grants you access to the festival for both Saturday and Sunday, usually at a discounted rate compared to buying two separate daily tickets. It is a single credential that must be retained for both days of the event.

What should I do if the tickets I want are sold out on the official site?

If the primary allocation is exhausted, our team can look into verified Japanese resale marketplaces to find tickets for you. We ensure all sourced tickets are legitimate so you can enter the venue without any issues.

Can international visitors pay for festival tickets using a foreign credit card?

While many Japanese ticketing sites reject foreign cards, our concierge service allows you to pay via credit card through our secure system. We also facilitate payments via Japanese convenience stores or ATMs if you are already in the country.
