Good to know
Tickets for Japanese music festivals are typically sold via eplus.jp or pia.jp, both of which accept foreign credit cards; convenience store pickup at Lawson (combini) is the most reliable collection method for visitors without a Japanese delivery address. Osaka summer and early autumn festivals can be very warm and humid, so lightweight clothing, sunscreen, and a portable fan are strongly recommended. Bring cash as many festival food and merchandise stalls in Japan operate on a cash-only basis. Arrive early to collect your ticket, check any large bags, and secure a good position — festival doors often open 60 to 90 minutes before the first act. Follow the official festival social media accounts for the latest venue confirmation, lineup announcements, and any COVID or entry policy updates.
