In recent years, energy constraints have been discussed from a historical point of view. This study aims at examining the copper industry’s energy use in Japan from the Meiji period to the time of World War I and clarifying the process of, and reasons for, the selection of energy sources. This study considered not only energy use in the large-scale mines but also energy use in the small-scale mines and miners’ homes. As a result, it was clarified that the mines changed into a space that was based on a diverse combination of energy sources, depending on differences in location (access to energy), natural conditions, financial power, the required amount and price of energy, energy use technologies, ore quality, and end product (usage).

近年来，已经从历史的角度讨论了能量限制。这项研究的目的是审查从明治时期到二战时日本的铜工业的能源利用我和澄清的过程，原因，能源的选择。这项研究不仅考虑了大型矿山的能源使用，还考虑了小型矿山和矿工家庭的能源使用。结果，据澄清，根据位置（获取能源），自然条件，财务实力，所需的能源数量和价格的差异，地雷变成了一个基于多种能源组合的空间。能源使用技术，矿石质量和最终产品（使用）。
