Osaka Bay is known more as a metropolitan area. Though not on the scale as Tokyo is, Osaka is still rather well known for it's industrial lands. Located on the western coast, it is also known for the fact that they have made some artificial island. The islands have been built for different reasons such as airport needs or other such things. The newest addition to the islands would be the battle grounds made for Programmers. The Programming grounds only recently opened up after creating the new artificial islands off the coast.
