I think yes.....
The 插座 in 日本 provide AC 100V, and in Taiwan it is 110V.
Over 90% machines in Taiwan and Japan can use both 110V and 100V.
If you are still worried, maybe you can review the 插座 limitation of all your machines.
And, there is another kind of 插座 in Japan, I remember it is 220~240V, don't worry, it looks much different from 100V, just like the 220V 插座 in Taiwan(sometimes for old air condition).
