Nosakadake, Mountain peak in Tsuruga, Japan

Nosakadake is a 913-metre mountain in Tsuruga, Fukui Prefecture, and the highest peak of the Nosaka range. Its summit area is a series of four peaks along a ridge: Ichinodake, Ninodake, Sannodake and the final summit, which holds a small hut and a shrine. The upper slopes are covered with beech forest, and the summit rocks are chert containing tiny marine fossils.

Nosakadake's trail is traditionally attributed to Kūkai (Kōbō Daishi), who in the early Heian period is said to have found a small clay Buddha about 7 cm tall in the mountain; it became revered as the Nosakadake Gongen. The Asakura lord Asakura Yoshikage also venerated it, and the image is kept at Sōfuku-ji at the foot of the mountain.

Nosakadake belongs to a group of peaks across Japan known as "hometown Fuji" mountains, named after their resemblance in shape to Mount Fuji. From the top, walkers can see Tsuruga Bay and the surrounding ridges on a clear day.

The main trail starts from Ikoido no Mori, where a road leads up to the trailhead past a campsite; a birdwatching hut and the Tochinoki Jizo water point lie along the way. The quieter Yamashu route follows a power-line inspection path with an unclear approach. Awano Station on the Obama Line is 40 minutes on foot from the trailhead.

Nosakadake is one of the few mountains in the area where the ascent can start from several different entry points, making each visit quite different from the last. Walkers who reach all three peaks find that each one looks out over a clearly different part of the surrounding landscape.
