In her book, Kamakura: Fact and Legend, Iso Mutsu calls Kakuon-ji a “venerable temple of unimposing exterior.” It is indeed quite simple on the outside (though wonderfully peaceful), but inside it houses a number of statues and other items, including two national treasures (the Yakushi Sanzon and the Black Jizo).
While the outer grounds are free to wander, getting a chance to see the temple’s treasures requires joining a tour for about ¥500. The tour takes roughly 50 minutes and is in Japanese. It’s only offered a handful of times a day, and not at all during certain times of the year (August, end/beginning of the year, rainy days), so make sure to google or contact the temple if you’re determined to join. Please note that photography is not allowed.
Founded: 1296 (built on the site a Buddha hall established in 1218)
Festival: Black Jizo festival, August 10
Trivia: Kakuon-ji is home to the Black Jizo, which is Jizo #3 of Kamakura’s 24 Jizo pilgrimage.
