Well this is certainly one way to increase your land base, though it isn’t anywhere near the fastest. As the result of an underwater volcano, Japan now has a brand new island to call its very own. There’s definitely less bloodshed involved in this than in your traditional land grabbing war, though this sounds like a difficult, painstaking way to expand the reach of your empire.
Located 620 miles South of Tokyo, the eruption went down a mere 500 meters away from Nishinoshima Island, an uninhabited subtropical landmass that is part of the Bonin Islands. You’d be correct if you assumed that this bit of geological action took place on the so-called “Ring of Fire,” as the archipelago does sit on the border of the Pacific tectonic plate. The string of islands number in the thousands, and ownership of them has come in handy in previous years to bolster claims to large areas of the ocean, as well as the energy and mineral resources those waters contain, which could potentially be very lucrative. In the past, Japan has used some of these islands to back territorial disputes with China.
