2026 Yokosuka Sports Arena Sub Arena Heated Pool Full-Day Course

The Sub Arena heated pool at the Yokosuka Sports Arena (Yokosuka Arena) is an indoor pool available year-round from April 1, 2026, from 9:30 a.m. to 9:00 p.m. Being an indoor facility, it is unaffected by the weather, which makes it easy to plan around all year. In the morning, enjoy the port-town scenery at Mikasa Park (三笠公園), where the memorial ship Mikasa is moored, then snack your way along Dobuita-dori, lined with Yokosuka's signature food. From midday it is finally time to enter the pool and enjoy water play until evening. Combining a port-town walk with an indoor pool, it is a one-day course for a relaxed time in Yokosuka City.
