138 Tower Park is home to that symbol of Ichinomiya's Skyline: Twin Arch 138. 138 Tower Park occupies 20.4 ha of the Kiso Sansen National Government Park, Japan's largest national park, which lies across Aichi, Gifu and Mie Prefectures.
Ichinomiya's symbolic tower - Twin Arch 138 - derives its name (and the height of it's tallest point) from the fact that the sound "ichi" also means "1," "mi" denotes "3" and "ya" can mean "8." In any case, the observation floor 100 meters up offers a fabulous sky panorama. Why not savor a delicious coffee or tea whilst soaking up the magnificent views from the Sky Lounge Big Tree restaurant on the observation floor, which serves light snacks, desserts, drinks and so forth.

Down on the ground is the Grass Park. Spread out on the lawn with your lunch, play a bit of ball - whatever takes your fancy. Over to the side, around 1,400 roses are planted in the Rose Stream, while cosmos and so on bloom beautifully - depending on the season - in the Flower Farm, Flower Maze and Flower Path. There are plenty of ways to enjoy the park, from the big open lawns where you can play freely, to the popular kids' play area with its soft play dome and large wooden multi-play equipment.
The park offers the fun of nature-watching; over on the west side, feel the fresh breath of nature in the Moku Moku Paradise nature area which features forests, mountains, hills, groves and ponds.

The free rest area Rest House Big Tree inside the park comprises stands selling the usual ice-creams and drinks, and also noodles and rice dishes, so you don't have to bring lunch with you. Of course, it's fine to eat food you've brought from home here too.
Another fascination of this park is how it anticipates the excitement of Christmas. Every year, the park is festooned in wonderful Christmas lights creating a splendid scene that can be appreciated from the observation floor as well as at ground level. It's now recognized as one of Aichi Prefecture's top illumination spots.
