Musashi Kyuryo National Park (Cosmos)

Overview

Nestled in the rolling hills of Saitama Prefecture, Musashi Kyuryo National Government Park holds the distinction of being Japan's very first national government park, opened in 1974. Spanning roughly 304 hectares — about 65 times the footprint of Tokyo Dome — the park preserves the natural undulations of the Musashino Plateau and weaves them into a landscape that transforms with every season. Walking its trails, you move between wild flower valleys, a peony and tree peony garden, a traditional Japanese garden, and open meadows that stretch toward the Kanto Plain horizon. Autumn belongs to the cosmos flower. As September gives way to October, broad swaths of the park fill with blooms in every shade the species offers: deep magenta, soft pink, pure white, and the warm yellow of the sulphur variety. The gently sloping terrain creates natural viewing terraces where visitors can look out over a sea of petals against the pale blue skies of a Japanese autumn. On clear days, the distant outline of the Kanto Plain stretches beyond the floral foreground, giving the scene an almost cinematic depth. Getting around the park's considerable expanse rewards planning. Rental bicycles are available near the main gate, and cycling paths loop through the most scenic zones. Beyond cosmos season, the park shifts through tulips and nemophila in spring, sunflowers and hydrangeas in summer, and wax plum blossoms in winter — making it a year-round destination for anyone willing to time their visit well.
