Momoiwa Observatory

A Floral Paradise with Giants Rising from the Sea

Experience the stunning harmony of rare alpine flowers and monumental rock formations on Rebun Island.

Located on the southern tip of Rebun Island, Momoiwa Observatory offers one of Hokkaido’s most iconic vistas. Here, you can witness the overwhelming presence of "Momoiwa" (Peach Rock)—a massive, uniquely shaped crag—contrasted against a delicate carpet of rare wildflowers. This breathtaking destination blends the raw power of nature with a serene floral beauty, offering a trekking experience unlike any other in Japan.

From the viewpoint, the sheer scale of Momoiwa is awe-inspiring. Looking toward the deep blue sea, you will find the charming silhouette of "Nekoiwa" (Cat Rock) nestled in the waves. In 2022, these vibrant alpine plant communities were designated as a National Natural Monument, recognizing the area as a global treasure of biodiversity.

The path from the observatory to Motochi Lighthouse is famously known as the "Flower Road." As the island’s premier trekking route, it invites you to walk through colorful blossoms swaying in the sea breeze. Every step reveals a dynamic contrast of rugged geology, fragrant flowers, and the vast ocean. This journey perfectly captures the resilient vitality and mysterious artistry of Japan’s northernmost frontier.
