Yamaguchi Kirara Expo Memorial Park is a comprehensive park located in Yamaguchi City, Yamaguchi Prefecture. It was created by developing the site where the "Yamaguchi Kirara Expo" was once held. The park is equipped with a variety of sports facilities, including a multi-purpose dome and soccer and rugby fields, and is also used as a venue for sports events and concerts. The spacious lawn is perfect for picnics and recreation, providing a space where families can spend their time as they like. You can spend your time in an open space while feeling the sea breeze.

One of the park's great attractions is the wide range of facilities for children. In particular, the large-scale playground complex, one of the largest in the Chugoku region, which just opened in June 2025, is expected to be bustling with many children. There is also the "Sun Hill" which makes use of the natural undulations, and the "Trim Square" with its athletic playground equipment, where you can move your body to your heart's content. In addition, you can enjoy playing in the water and looking for creatures at the artificial beach "Moon Sea", which is especially popular in the summer.

[Useful points of concern]
The park is very large, so it will take a lot of time and energy to see everything. The sun is particularly strong in the summer, and there are few shady areas, so it is important to take precautions against heatstroke. When large events are held, the surrounding roads and parking lots are expected to be very crowded, and public transportation is also likely to be congested. It is practical to check the event information on the official website in advance and consider the congestion situation before visiting.
