If you are a softbank user, you should use paypay and shop at uahoo shooping.
If you pay using paypay you get at least 7% points back to paypay. 1 point =1yen
Points can go up to 20-30% sometimes as shown in pic.
On top of that, you can invest your points so if stock market go up you get more points
*You get choose from gafa stocks or sp500 i think
So because its points not actual money you dont have to pay any tax on it.
I’ve doing this for like a year now.
Its so much cheaper than amazon most of the time but I’ll still check Amazon and other places every time to make sure.
