Quality minerals/vitamins high street shop only.

Amazon, is killing me. So frustrated with it and with the way it’s changing.

Does anyone have a recommendation for a high street shop where I can walk in today (Kanagawa or Tokyo) and buy more obscure minerals and vitamins?

I’ll save you some time, I already have an iherb account and I can’t find what I want through ‘nature made’, or the regular pharmacy shops.

Thanks.
