The Himekawa headwaters, a group of springs near national roads and private houses, are extremely rare as the headwaters of first-class rivers. From the promenade, you can see a colony of Amur adonis, ranunculus nipponensis, and rock fish swimming in clean water up close. The adjacent “Okaumi Marsh” is a treasure trove of rare plants that you should definitely visit, and has been selected as one of the 100 best waters in Japan. Biking is prohibited in the park, so leave your bicycle and walk around.
