A light outdoor event called "SENNAN LIGHT OUTDOOR DAY" is coming to SENNAN LONG PARK (Southern Street / サザンストリート) in Sennan City, Osaka on Saturday, March 28, 2026. The event runs from 12:00 PM to 7:00 PM and is free to enter.
Set along a stretch of coastline where beach, lawn, and open plazas connect seamlessly, the event is designed to make outdoor and camping activities approachable — even for first-timers who may have felt put off by gear or skill requirements. Visitors are welcome simply to browse and take in the atmosphere.
Bonfire

The event blends outdoor and indoor elements, offering a relaxing experience where visitors can watch bonfire flames against the backdrop of the sea. With the cool ocean breeze in the air, the warm glow of the fire brings people together for a special moment that is both calming and uniquely outdoors.
Outdoor Workshops
Wood Burning Tag Workshop

Participants write a name or meaningful word on a wooden tag, then use the heat of a bonfire flame to burn the design into the wood. The finished piece is one-of-a-kind and can be taken home as a keychain or good-luck charm.
- Adult: ¥1,000
- Student discount (high school age and under): ¥700
Bubble-Making

Taking advantage of the sea breeze blowing through SENNAN LONG PARK, this activity lets visitors release bubbles into the open sky and watch them catch the light as they drift upward. The wide-open outdoor setting makes it a memorable experience.
- Fee: ¥500
Laser Tag Battle

A team-based laser tag battle that can be enjoyed by both kids and adults. Armed with real-looking laser guns, participants work together to form strategies and take on missions as a group.
- Fee: ¥1,000
Photo Spot

A dedicated photo area is set up using camping gear and bonfire decorations against the backdrop of the sea and sky. The natural lighting at this coastal location means every angle is photo-ready, making it easy to capture memories of the day.
Food Trucks

Food trucks serving light bites and drinks will be on-site throughout the event, adding to the festive atmosphere. Visitors can take their time relaxing with food and refreshments surrounded by camping gear.
Market

The event features a collaboration with COMFES, one of the largest fashion festivals in the Kansai region. Professional vintage clothing shops, boutiques, and brands will come together in a friendly space where conversations with vendors are part of the experience. The focus is on direct connections between makers, sellers, and visitors sharing the same space.
