If you won the lottery of any amount
I personally would buy a small house in Japan and move there after which I would live simply and retire
And get a Japan citizenship
I don’t believe in buying expensive things it’s a waste of money and it would just cause you to go broke faster
So I would only spend on what I have to
Houses in Japan are pretty cheap but very nice
And start a international food restaurant in Japan
Assuming it's 1,000,000 Save 75% for all different purposes, buy a James Hattfield Signature guitar, an Ibanez 5 string bass I love, buy an 8 string Ibanez or LTD I don't know any good models though, buy a decent used car at about 5,000 bucks, build a gaming PC at about 5,000 I guess, buy some air force ones shoes, an obsidian ring, some nice clothes and shoes.
I did the math in everything. I just wasted 30 minutes if my day
