I think chemical warmers are not classified as dangerous goods and can be carried in both carry‑on and checked baggage.

Ok thanks

no problem buying it here and bring it overseas....saw many people did that

I'm doing shiga kogen (yakebitaiyama) for the first time this season. Starting on christmas day but man this year the weather forecast seems to be above zero from this weekend onwards (not to mention it seems like the mountain is only half open and not much snow forecast. Sad.

Wew nice! I only visited yokoteyama I think 23/24 season..wanted to also visit kumanoyu for its ungroomed terrains

Yea, the weather sucks..a couple of days ago I was at lotte arai, started the season with slushy snow everywhere. I think a lot of ski resorts are having a bad time except hakuba at the moment
