Beautiful literal oasis in the middle of downtown, not too far from the center of Sakae. It's easily accessible via the underground areas where subway exits are but also accessible by foot.
The bottom floor had coin lockers, food, shopping and sitting area. The open space will also often have different activities depending on the season. It also offers an entrance into the Annex, another underground shopping tunnel that leads you to Tokyu Hands.
The grassy area is also a comfortable, clean area where you can rest or sit and enjoy snacks. The top is where the goods are! You get a scenic view of the water landmark, Nagoya tower and sites of the big billboards of Sakae.
Definitely worth visiting, even for a short while, to snap a few photos of this urban park.
