This Buddhist temple is the oldest in Tokyo and is dedicated to Kannon Bosatsu, the Bodhisattva of Mercy. Situated near the Sumida River, the temple is one of Tokyo’s most popular sites. Enter through the Thunder Gate and you’ll encounter a street of vendors selling souvenirs like yukatas, fans, and local snacks. That path will lead you to the inner gate, Hozomon Gate. Past that is the temple itself. Be sure to go inside and look up—some of the most impressive artwork is on the ceiling.
