As an archipelago, Japan is an island chain and is surrounded by water. The water acts as a natural and geographical barrier, separating the country from its nearest land neighbor (Manchuria and Russia on the Asian continent) by 100-200 miles at the closest points. For the most part, Japan is separated from other islands and large land masses by thousands of miles of ocean.
