From the low-voltage urban distribution of electricity in the early Meiji era to the formation of the ultra-high-voltage long-distance power transmission network in the Showa era, all within just a few decades.

This remarkable progress sometimes required the import of advanced technologies, but engineers in each era strived for domestic production, and Japan's power transmission technology reached the world's top level.

This film looks back at the dawn of long-distance high-voltage power transmission in the Meiji and Taisho eras,
tracing the progress and efforts of these technologies.
