Korankei (香嵐渓, Kōrankei) is a valley near Nagoya reputed to be one of the best spots for autumn colours in the Chubu Region. Shaping the valley is the 254 meters tall Mount Iimori, on which Kojakuji Temple stands. In the 17th century, the head priest of Kojakuji planted some maple trees along with the temple approach, prompting many locals to do the same in the area. Today, visitors to Korankei can see the fruits of these past efforts, in the form of excellent autumn scenery that peaks around mid to late November each year. The best colours tend to appear around the paths along Tomoe River at the western and southern sides of Mount Iimori. Visitors can enjoy lovely sights of maple tree tunnels and autumn colours in combination with views of the river and the few bridges across it. The vermillion Taigetsukyo Bridge is the symbol of Korankei and a great picture-taking spot. https://www.japan-guide.com/e/e3316.html

During the Edo Period (1600-1868), Nagoya served as the seat of the Owari, one of the three major branches of the ruling Tokugawa family. The family amassed great wealth that was only surpassed by four of the 200 feudal domains of the Edo Period. The Tokugawa Art Museum (徳川美術館, Tokugawa Bijutsukan) was built on the grounds of the Owari's former feudal residence and preserves and exhibits several of their treasures including samurai armour and swords, tea utensils, noh masks and costumes, poems, scrolls and maps. https://www.japan-guide.com/e/e3303.html

In 1610, Ieyasu Tokugawa began construction of Nagoya Castle as a castle residence for his son Yoshinao. It was lost to flames during WWII, but the large donjon (approx. 48 m) with golden "shachi" ornaments adorning its roof and the small donjon (approx. 24 m) was rebuilt in 1959. In the large, five-story donjon, sliding door murals which are an important cultural property and historical information are displayed; and on the third to fifth floors, you can see a full-scale replica of a golden shachi ornament, experience the pulling of stones used in the castle's construction as well as riding in a palanquin, and come to know the sights and sounds of life within the castle and the castle town. Anyone can enjoy themselves as they learn the history of Nagoya Castle and the city it resides in. http://www.nagoya-info.jp/en/see/facilities/nagoya_castle.html
