Sagamihara Shiroyama Katakuri Village: Flowers and Tanzawa Nature

Close to central Tokyo, Sagamihara City in Kanagawa is a nature-rich area cradling the Tanzawa mountains and Lakes Sagami and Tsukui. In spring, colonies of delicate katakuri lilies color the slopes; summer brings lakeside outdoor activities and autumn brings foliage, letting you enjoy nature through the seasons. It is loved by many as an easily reached retreat.

Highlights

Sagamihara's signature flower spot is Shiroyama Katakuri Village. Roughly 300,000 katakuri lilies grow wild here, and the sight of the pale-purple, downward-nodding blooms spreading across the mountain slopes is spectacular. The grounds also hold rare white-flowered and yellow-flowered katakuri, said to arise from mutation. Beyond katakuri, spring wildflowers and flowering shrubs such as hepatica, mitsumata, rhododendron, and wild cherry bloom in succession, wrapping the hillside in the colors unique to a countryside village.

Seasonal Enjoyment

Katakuri Village is open to the public only during the spring flowering, typically from early March into mid-to-late April. The katakuri peak runs from mid-March into early April. Sagamihara also has Lakes Sagami and Tsukui, where lakeside outdoor pursuits such as boating, fishing, and camping can be enjoyed in summer. In the fresh-green and autumn-foliage seasons, the lakes and mountains create beautiful scenery ideal for driving and hiking.

Access and Essentials

Access to Shiroyama Katakuri Village is about 15 minutes by bus from Hashimoto Station on the JR Yokohama Line and Keio Sagamihara Line, alighting at Shiroyama Sogo Jimusho Iriguchi, then about a 20-minute walk. During the open season, temporary direct buses sometimes run from near Hashimoto Station. Admission is 500 yen (free for elementary students and younger), and it is open from 9:00 until sunset. There is free parking, and it is easily reached by car from the Chuo and Ken-o Expressways.

Practical Travel Notes

Katakuri flowers open in sunlight and are often closed on cloudy days and early mornings, so a daytime visit on a clear day is recommended. Peak weekends are crowded, so allow plenty of time. The grounds involve walking a countryside slope, so sturdy shoes are reassuring. Allow about an hour to stroll the site. Pairing it with a drive around Lakes Tsukui and Sagami or the foothills of Tanzawa makes for a full day in nature.

A Word of Advice

Katakuri have a short flowering window and are sensitive to weather. Checking the open status and bloom updates in advance and choosing a clear day is the surest way to meet these delicate colonies in full bloom.
