Breathtaking Panoramic Views and Award-Winning Architecture

Located atop Mt. Kirosan on Oshima Island in Ehime Prefecture, Kirosan Observatory Park offers one of the most stunning views in all of Japan. From its 307-meter-high vantage point, visitors are treated to sweeping vistas of the Seto Inland Sea, the iconic Kurushima-Kaikyō Bridge, and the intricate web of islands that define the Shimanami Kaido. Designed by world-renowned architect Kengo Kuma, the observatory blends seamlessly into the natural landscape, creating an awe-inspiring visual and emotional experience.

A Scenic Wonderland Across All Seasons

Whether you visit in spring with cherry blossoms, summer with crystal-clear blue skies, autumn with fiery foliage, or winter with crisp air and golden sunsets, Kirosan Observatory Park transforms with the seasons. The park is particularly magical at dusk, when the setting sun paints the sea and sky in rich amber hues—perfect for photography or quiet reflection. It’s also a beloved stop for cyclists journeying along the Shimanami Kaido.

Easy Access and a Peaceful Retreat Above the Sea

Just a 30-minute drive from Imabari City, Kirosan Observatory Park is a convenient and rewarding detour for travelers exploring western Japan. Ample parking, rest areas, and clear signage make it welcoming for families, couples, and solo travelers alike. It’s not only a visual feast but also a chance to slow down, breathe deeply, and appreciate Japan’s natural artistry.
