Kurokuma Falls is a waterfall in the town of Ajigasawa, Higashitsugaru District Aomori Prefecture, Japan, on a tributary of the Akaishi River, which flows down from the World Heritage Site Shirakami Mountains. It is one of "Japan’s Top 100 Waterfalls", in a listing published by the Japanese Ministry of the Environment in 1990.
Facts from Wikidata and Wikipedia, compiled September 2026; season and access are our estimate, not a visit report. How we build these pages.
Kurokuma Falls drops over a series of steps on the Akaishi River. It is a cascade-type fall, and the nearest base for a visit is Ajigasawa, Japan. Access to the main viewpoint is rated moderate.
Summary adapted from the Wikipedia article (CC BY-SA 4.0).
As a cascade waterfall, water tumbles down a series of rock steps rather than falling free.
No commercial adventures run at Kurokuma Falls itself — the experience is the approach and the view. Guided day trips from Ajigasawa are the easiest way to combine it with the area around it.
