Tashimagahara Primrose Habitat (First Designated Area)

Overview

The Tashimagahara Primrose Habitat, located in Sakura Ward, Saitama City, Saitama Prefecture, is a nationally designated Special Natural Monument of Japan. Approximately 4.2 hectares of land, nestled between the Arakawa and Kamo Rivers, is home to a thriving population of delicate primroses. During the Edo period, primrose appreciation flourished, drawing many visitors to Tashimagahara. However, river improvement projects and urban development since the Meiji period drastically reduced the primrose's habitat. Thanks to the efforts of local resident Sadateru Fukai and botanist Manabu Miyoshi, the area was designated as the very first Natural Monument in 1920. It was upgraded to a Special National Natural Monument in 1952 and continues to be carefully protected as a precious primrose habitat. Tashimagahara primroses have a deep connection to human culture, having been collected, cultivated, and traded at high prices by Edo-era hatamoto (bannermen) and Meiji-era enthusiasts. Furthermore, Tashimagahara is considered to preserve the landscape of the Arakawa River basin as it was before the Taisho era, giving it significant value as an environmental historical record. In spring, the sight of primroses blooming across the entire area captivates many with its beauty. Sakuraso Park has been developed in the surrounding area, with walking paths and parking available, making it easily accessible. Active efforts are underway to remove invasive plants that threaten the primroses and to conserve the environment. Tashimagahara Primrose Habitat is a precious place where nature, culture, and history converge. Be sure to visit and experience its charm.
