Anraku-ji (安楽寺) is a Buddhist temple of the Sōtō school in Bessho Onsen, Ueda, Nagano Prefecture, Japan.

The main hall (hon-dō) has a thatched roof and enshrines an image of Sakyamuni flanked by Manjusri and Samantabhadra as principal object of worship.

The inside contains an octagonal Buddhist altar which together with the pagoda and a munafuda ridge tag with information on the building's construction has been designated as National Treasure in 1952.

Built to store sutras copied by the priest Tetsugen purchased from Mampuku-ji, the building is 5.4 m (18 ft) square, plastered and has a copper roof.

[5] Built in 1769 in a mix of Zen and Japanese style, the two-storey bell tower (shōrō) with a skirt like lower storey (hakamagoshi type) is one of the largest in the area.

In addition, the temple owns a set of sixteen rakan (i.e. arhat) also from the Edo period.
