Must-See Spots along Oirase Gorge
The full 14-kilometre hike takes a full day, but for a shorter visit, the middle section (around 3 kilometres) offers stunning highlights without a lengthy trek.
(1) Moss Wonderland
Home to over 300 moss varieties, these tiny plants thrive in the gorge’s humid environment, creating a lush, emerald-green carpet. Moss, a cryptogamic plant, thrives directly on rocks without the need for roots. As it decays, it enriches the soil with organic matter, fostering the growth of other plants. Beyond its role in soil formation, moss helps regulate air humidity, retain soil moisture, absorb rainwater, and prevent erosion. It also provides shelter for small animals, contributing to the area’s rich biodiversity. The constant flow of water from the Gorge’s waterfalls creates the perfect conditions for moss to flourish, making it a captivating natural feature for visitors to admire.

(2) Kumoinotaki Falls
Kumoinotaki Falls is a breathtaking three-tiered waterfall, standing approximately 20 metres tall. Its powerful cascade tumbling down the steep cliff creates a mesmerising sight, whether admired from a distance or up close. Conveniently located near a bus stop, it offers easy access for hikers and nature enthusiasts, making it a must-visit highlight along Oirase Gorge.
(3) Sensujinotaki Falls
While the middle section of Oirase Gorge is known for its grand waterfalls, smaller cascades like Sensujinotaki Falls offer a more tranquil charm. Its name, meaning "thousand threads" in Japanese, reflects the waterfall’s delicate, flowing streams. Though modest in size, its serene ambience makes it a perfect spot for photography and quiet reflection.
(4) Ashuranonagare Current
Beyond its waterfalls, Oirase Gorge is also renowned for its dynamic rapids. Ashuranonagare Current, named after the fierce warrior deity Ashura, features turbulent, fast-flowing waters that evoke the intensity of a battle.
