Imagine going on a trip where you can send your luggage ahead of you so you don't have to struggle with multiple bags getting to & from the airport.
Well in Japan they have takkyubin, a service where you can do just that. You send your luggage ahead of you so that you only need minimal hand luggage. Travel becomes simpler and less stressed if you are not burdened with bags, It works well because its reliable, secure and reasonably priced. Arriving at a hotel and finding your luggage already in your room is joyous.
I would happily use such a service if available elsewhere.
