Roll up the streets you know,roll on to the Japan you don't.
Shiba Park, Tokyo / Game in development
What kind of game?
A game about rolling a ball across Japan and picking up buildings to make it grow bigger.
At first you can only pick up street trees and cars. As you grow, you can roll up houses, office towers and bridges, and see farther and farther. Real streets and terrain are recreated from PLATEAU — the 3D city models of Japan's Ministry of Land, Infrastructure, Transport and Tourism — elevation data from the Geospatial Information Authority of Japan, and other sources. Roll through the streets you know and over the mountains you've always seen. Towns you've never seen, islands across the sea — you can roll up all of it.
Roll anywhere
Roll the ball and you'll bump into rises and dips you never expected. Ground that looked flat on the map turns out to be surprisingly bumpy.

Chiba
Valleys of the Shimōsa Plateau
Finely branching valleys cut into the plateau. Trees still cover the slopes, and up on the plateau and down in the valleys, the land is used in completely different ways.
-
Kyoto → Wakasa Bay
A fault valley running straight north
From downtown Kyoto, a valley runs straight north all the way to Wakasa Bay — carved by the Mikata and Hanaore faults.
-
Naka, Tokushima
The winding Naka River
Deep in the mountains, the valley twists and turns without end. Where the river has shifted its course, it has left behind rare patches of flat land.

Tokyo → Hachijō Island
A volcanic island 290 km away
About 290 km south of Tokyo. Roll across the sea, and an island made of two volcanoes joined together rises ahead.
