-based trading company, Matsuda-ya, began modern mine development at an altitude of at the base of the peak of Higashi-Hachimantai. In 1934, the Japanese Government Railway Hanawa Line was extended to near the mine, and Ōbuke Station was established. At one point, the Matsuo mine accounted for 30% of Japan’s sulphur production and 15% of its pyrite, boasting that it had the greatest production in Asia. In the late 1950s, it was the third largest mine in Japan in terms of tonnage of ore: 469,000 tons of iron ore and 200,000 tons of sulphur. However, in the 1960s, the demand for sulphur was less, and the production of low-cost sulphur as a byproduct of
