The Hida overnight ridge traverse from Nishihodaka to Okuhodaka, also often called Gendarme, is supposedly Japan’s most dangerous hike. This hike is very exposed and only for very experienced hikers. People fall and die every year so proceed with caution. It's not called Japans most dangerous hike for nothing. If you’re looking for a truly thrilling experience this is your hike. Helmet, gloves and climbing experience needed!

The Shimonoroka in the Kurobe Valley is a very exposed and complex 2-day hike with dramatic and incredibly scenic views of the Kurobe river. The valley can only be walked for a very short period from September to October because of snow and missing bridges/ladders.

Some years, it might not open at all. Before embarking on this hike, make sure the valley is passable.

The Daikiretto is the second half of the Hida ridge, continuing from Okuhodaka to Minamidake or even further to Yarigatake. Just like Gendarme it's very exposed and technical.

Proceed with caution, this hike is more climbing then walking and don't forget to bring gloves and a helmet. It's usually walked in 2-3 days.

Kasagadake is another streneous and steep overnight hike in Gifu. You have more than 2100m elevation gain to the hut and the trail is not easy with lots of unstable boulders. The views are amazing tough and is well worth the effort. It's also a lot less busy than other hikes in the area and a good choice for the Kamikochi area.

Osugidani valley is an advanced in-and-out dayhike in Mie. It's one of Japans top 3 most beautiful valleys and accessible from spring to fall.  The valley receives a lot of rainfall and it's notoriously hard to get a good weather day. Spring and fall usually have the best weather and no or less mountain leeches. The hike is always a bit wet and slippery and it's very exposed with most parts secured by chains.

The traverse from Shinhotaka through Kumonodaira and along the Yomiuri Shindo is an incredibly 4-6 day hike in the Northern Alps. The route is very strenuous, long and remote. The area also often gets called “last undiscovered region” and it’s truly off the beaten path for hiking in Japan. If you are flexible with time and have experience with hiking in Japan this is an amazin route.
