In this Japanese garden you can see and feed koi fish in large ponds, take a look at the tea ceremony house, and also view the beautiful waterfall. On spring the plum trees bloom beautifully and on autumn you can enjoy the night illumination.

熱田神宮 Atsuta Jingū
This shrine houses the sacred Kusanagi no mitsurugi (草薙神剣) sword, one of the three Imperial regalia of Japan — but unfortunately nobody but the emperor and a few high priests get to see it. There are some 4,400 other artifacts on the grounds though and the shrine hosts some 70 festivals every year.
大須観音
Founded in the Kamakura era (1192-1333), this temple was moved to its current location by Tokugawa Ieyasu in 1612. The present main temple on the site was reconstructed in 1970. Check out the main hall or buy an お守り (omamori) charm in the gift shop for good luck. The grounds in front of the temple are host to a small flea market twice every month.
荒子観音
This small temple is the oldest building in Nagoya, with original construction on the site dating from the Heian Period (8th century). Despite several fires which destroyed older portions of the temple, the Tahoto pagoda on site remains intact after 472 years.
