Aichi PrefectureSheep-shaped inkstone from a kokufu site
Sheep inkstone, Mikawa Kokufu01 ／ Nagi tree
The nagi behind Kumano Shrine is about 20 m tall and estimated to be over 300 years old, according to the tourist association. The nation designated it a natural monument in 1938. Its parallel-veined leaves are hard to tear, and they were used in amulet pouches, it is said, in the hope that a couple's bond would not break.
02 ／ Pine avenue
Between the Goyu and Akasaka post towns on the old Tokaido, about 560 m along the prefectural road is designated a national natural monument. Old documents show that about 650 pines were planted in the Edo period; about 350 remain now. The city board of education and a local pine-avenue preservation society carry out protection work.
03 ／ Inn
Ohashiya is an inn on the old Tokaido at Akasaka, known in the Edo period as Koiya. A city-designated building, it was conserved and repaired with the main aim of restoring the look of an Edo-period inn, and from the second-floor room you can look down on the old Tokaido through the lattice. In 1733, 83 of Akasaka's 400 houses were inns.
