Transformer substation of Hitachi plane Tachikawa factory leaving explosion trace of an awful lot of machine-gun mopping-up and bombs at one corner of metropolitan Higashiyamato south park in the southwestern part of Higashiyamato-shi is built.

This building was important facility which supplied electricity to munitions factory which produced engines of airplane that construction was started in Tokyo prefecture north Tama county Yamato-son at the time in 1938 (Showa 13).

In 1945 (Showa 20), we received air raid of the repeated U.S. forces like munitions factory of other Tama area, and holy life of 111 people including employee and family in total was lost. Particularly, reason, 28 died when 78 people were bombing of bomber B-29 on April 24, and more than 1,800 bombs were dropped by shooting by fighter Grumman on February 17. In addition, we were told that 80% of factory was destroyed by bombing of this verge, and it was in a situation that we could not operate factory.

However, fortunately, transformer substation made with reinforcing rod is decisive; continued still operating as facilities to receive of postwar non-military industry without being injured, and continued working as transformer substation until 1993 (Heisei 5). Meanwhile, we continued being used without almost adding hand of restoration.

Transformer substation as war damage remains

Voice of many people who desired peace grew, and Higashiyamato-shi obtained this building by transfer from company and got understanding and cooperation of Tokyo and appointed this building in cultural assets of city on October 1, 1995 (Heisei 7). In addition, from 1993 (Heisei 5) through 7 (1995), we carry out present situation investigation and restoration construction and wrestle for preservation of building.

70 years after the war or more are over, and population born in postwar period exceeds 80% of total population of Japan. People that war was experienced decrease, and it becomes difficult year by year to hand down the memory in now.

Such inside, transformer substation are existing very valuable war damage buildings while leaving innumerable holes by piece of machine-gun mopping-up and bomb in the war damage in wall surface. On the other hand, deterioration of building advances including staying outer wall or internal pillar of bullet hole, and large-scale restoration construction is necessary.
