If you buy something in Japan and plug it in Australia, you are going to fry it. The voltage is 110 in Japan and 120 in the US. I think most appliances that use adapters are fine going from Japan to US or US to Japan, but I wouldn't try Japan and US to Australia or EU. You should be okay with your US converter and power strip plan, but I am no expert as I doubt anyone on here will be.
