You mean Yodobashi as in visiting the physical store?
If so, yes. You can request for the 5% tax refund as long as your purchase is more than 10,000 yen. If you can't speak Japanese, just show them your passport, they'll understand.
Else look out for those sales staff wearing the language armbands meaning they can speak Chinese/English.
Yes, visiting the store. Will be going to Japan next week and if there will be a 5% tax rebate, it will be great to get it there.
Thanks for the info.
