Several coal deposits are located in the northern part of the island, concentrated in Fukushima Prefecture and Niigata Prefecture , though Honshu's coal production is negligible in comparison to Hokkaido and Kyushu . Most of Japan's oil reserves are also located in northern Honshu, along

The name of the island, Honshū ( 本州 ) , directly translates to "main province" or "original land" in English. Humans first arrived in Honshu approximately 37,000 years ago, and likely earlier.
