Clarifying Japan's 100V voltage standard

Japan uses 100V as its standard, with a tolerance range of 95V to 107V (101V ± 6V at the supply point). The "101V" is the value to maintain, technically. For appliances requiring 200V, the allowed voltage range is 182V to 222V. I'll cite the Kansai Transmission and Distribution source.

以100V作为居民/商用市电标称电压的国家，主要就是日本（部分回路也会有200V）。(kansai-td.co.jp)

日本对“100V”供电的允许波动范围，在《电气事业法施行规则》第38条写得很明确：当标准电压为100V时，供电地点电压应维持在101V 的上下 6V 以内。(法令文庫)

所以换算成范围就是：

（同条还规定：标准电压为200V时是 202V±20V，即 182V～222V。(法令文庫)）
