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

Ohara (大原, Ōhara) is a rural town nestled in the mountains of northern Kyoto, about one hour from Kyoto Station, but still technically located within Kyoto's city limits. Ohara is best known for Sanzenin Temple and particularly popular in mid November during the autumn leaf season, which typically occurs about one week earlier than in central Kyoto. https://www.japan-guide.com/e/e3932.html

The image of the temple richly adorned in gold leaf reflects beautifully in the water of Kyokochi, the mirror pond. It is perhaps the most widely-recognized image of Kyoto. Seen reflected in the adjoining "mirror pond" with its small islands of rock and pine, Kinkaku-ji Temple, "The Temple of the Golden Pavilion," is a breathtaking must-see. The building's first purpose was to serve the retiring Shogun Ashikaga Yoshimitsu (1358-1409) as a residence. The gold-leaf-adorned building was converted into a Zen temple shortly after his death. In an event that was later fictionalized by the renowned author Yukio Mishima, a 21-year-old monk burned Kinkakuji down in 1950. The temple was rebuilt in 1955 and continues to function as a storehouse of sacred relics. The temple's garden is also a scenic delight and contains in its grounds a charming teahouse. https://kyoto.travel/en/shrine_temple/165
