In Nagasawa area of Toyokawa there is a wooden monument which shows where the pair of Ichirizuka mounds used to be located. Ichirizuka mounds are the milestones built for Old Tokaido travellers to tell the distance from Edo. On top of the wooden monument there is a paintng that shows how the mounds used to be during Edo period.
The shrine at the foot of former mountain fortress is one of the Shinto-Buddhism hybrid shrines in Japan. The origin of the shrine was not known but as the wooden ridge tag of main hall shows the main hall was built in 1403. Thus it could be more than 600 years old. It was moved from former palace area to the current Ganrakuji fort area then owned by Matsudaira Clan around mid 16th century. It was also recorded that third Shogun Iyemitsu sent his men to visit the shrine on his behalf in 1634. The name of the shrine was changed to current Hachioji Jinja in 1880 because of Meiji Government's order to seperate Buddhism and Shintoism. The shrine grounds are really quiet and peaceful. Some Tokaido visitors come all the way to detour there. The shrine steps and stone wall structure is really well-made. The shrine also has some jizo statues and a Koshin tower.

Sekai Shindokyo is Shinto-related new religion in Japan founded in 1944 by Hide Aida. It is somewhat off-shoot of Tenrikyo based in Tenri, Nara. The headquarter of Sekai Shindo-kyo in Toyokawa is known among tourists who love to go to peculiar places. To get inside the grounds of the shrine you need to ask permission and they will give you a brief guided tour. I am not so sure if there is English guide available. Ordinary tourists to Toyokawa just take some photos of huge padoda-styled building from outside. It is quite huge.
At the northwest of Toyokawa Inari there are some nice parks such as Inari Park and Sakuragaoka Park which are only about 100 meters apart to each other. Inari Park is closer to the Toyokawa Inari about 100 meters nothwest of Toyokawa Inari Fox Mound. It is a nice park with huge lawn area, a small open air stage for events, fountains and a playground for children.
