I'm about to take my first trip to Japan (very excited!)
I am aware that tipping is very much frowned upon and might even be considered insulting.

We'll be staying in decent hotels and with the language barrier I expect we may be needing the concierge more than usual.

I understand that giving a small gift is appreciated, often something from my home area. Is this appropriate for a concierge? If so, what sort of thing should we gift? How much (ish) should the token of appreciation cost?
