1. Universal Studios Japan Lagoon
For Osaka's listed New Year's Eve fireworks, the park lagoon is the main spot to aim for. The display is part of NO LIMIT! Countdown 2027, with the countdown moment scheduled from 11:50 p.m. to 12:05 a.m. and about 5,000 fireworks advertised around the park. You'll need a paid Party Pass to attend, and park food and drinks are available during the event. The lagoon is the event's countdown location, so plan to stay inside the park rather than expecting a view from outside.
