2026 Full-Day Course: Oizai Park Pool

This full-day course centers on Oizai Park Pool (大在公園プール) in Oita City, which is open from 10:00 AM to 5:00 PM from Monday, July 20 to Sunday, August 30, 2026. It features a 50m x 20m main pool (1.0-1.2m deep) alongside a 0.4m-deep kiddie pool - and admission is completely free. Being able to use a pool of this scale at no cost is a real blessing for families. You can use the pools differently depending on your needs: swim freely in the main pool, or let children who are just starting to get used to the water take their time in the kiddie pool. In the morning, get moving on the wide lawns of Oita Sports Park (大分スポーツ公園), then take in the ocean views at Tanoura Beach (田ノ浦ビーチ) overlooking Beppu Bay, before heading to the pool in the early afternoon. Being close to the sea, Oizai offers a breezy summer day all its own. Note that the pool will be temporarily closed from 4:00 PM to 5:00 PM on August 3 due to rising water temperature, so if you're visiting that day, plan to wrap up earlier. Check Oita City's official website for opening days and operating details.
