2026 Hikarigaoka Park Keyaki Plaza Water Feature: Full-Day Course

Hikarigaoka Park in Nerima City has a free water play area, the Hikarigaoka Park Keyaki Plaza Water Feature (Wading Pool), where water flows only in summer. The 2026 season runs Wed 7/1 to Wed 9/30, from 10:00 to 16:00. However, it does not operate on 7/14 to 21, 8/12 to 14, or 9/14 to 16, and sudden suspensions are announced on the park's official X account, so checking before you set out is essential. The venue is Hikarigaoka Park in Nerima City. One of the largest parks in Tokyo, it has the water feature spreading beneath an avenue of zelkova trees, with shade and lawn right beside it, which families with children appreciate. Admission is free and there are restrooms in the park. There is no changing room, so wearing a swimsuit underneath your clothes or bringing a towel poncho keeps preparation short. In the morning, enjoy the scents of herbs and flowers at the Shiki-no-Kaori Rose Garden, watch wild birds at the Bird Sanctuary in Hikarigaoka Park, then have lunch at Hikarigaoka IMA. In the afternoon, return to Keyaki Plaza and focus on water play until closing. You can walk the whole route from Hikarigaoka Station on the Oedo Line (大江戸線), making it an easy neighborhood outing to plan even without a car.
