Among field athletics (outdoor obstacle courses) outside Tokyo in the Kanto region, the wooden courses in Tochigi’s prefectural parks cost ¥400 for adults and ¥200 for elementary and junior high school students. Forest Adventure, where you cross between trees in the forest, starts at ¥1,900 for the net course at Ryugasaki, about 5 times the prefectural parks. Whether preschool children can play depends on the facility: Igashira Park and Nasunogahara Park are for elementary school students and older, while the lower courses of Forest Adventure accept visitors 90 cm tall and over.
In short
- To go around cheaply: Igashira Park and Nasunogahara Park (both ¥400 for adults, ¥200 for elementary and junior high school students).
- With children younger than elementary school age: the lower courses of Forest Adventure Ryugasaki, Ueno and Tarzania (from 90 cm tall).
- By train and bus: Sagamiko Mori Mori (8 minutes by bus from Sagamiko Station), Sagamihara Asamizo Park (by bus from Sagami-Ono Station).

For a family of 4 (2 adults and 2 elementary school students), a single visit costs ¥1,200 at Igashira Park and Nasunogahara Park and ¥4,600 at Arinomi. Musashi Kyuryo is free for junior high school students and younger, so it is ¥900 for 2 adults, plus ¥700 for a standard car’s parking.
2. Good to know when choosing a field athletic in Kanto
Some facilities cannot be used when the equipment is wet from rain, so check whether they are open on the day after rain. Igashira Park may close temporarily when the equipment is wet, and Nasunogahara Park also suspends use when it is wet from rain.
The easiest to reach by train from Tokyo are Sagamiko Mori Mori, by bus from Sagamiko Station on the Chuo Line, and Sagamihara Asamizo Park, by bus from Sagami-Ono Station on the Odakyu Line. Facilities in Tochigi, Gunma and Ibaraki are often 15 to 45 minutes from an expressway interchange, and Forest Adventure Ueno is 45 minutes from Shimonita IC.
Facilities have shoe rules: Igashira Park does not allow sandals or high heels, and at Motegi’s DOKIDOKI, visitors in shoes unsuited to exercise change into rental shoes. Igashira Park advises bringing a change of clothes and spare shoes.
