Yes, actually I would be more interested if this was more radical. I have been to Japan 4 times already (last one was in February).

For the kind of travel I am interested in, renting 99% of my stuff at the arrival would be fine. But:

1) there are some things (e.g. contact lenses liquid, aikido uniform) who may not be included anyway because somehow of a "niche" requirement.

2) I still need to take back much more stuff than what I took with me on my incoming flight. Of course most of it could just be sent by post (and surface travel, i.e. by ship, would still be ok for most of it).

But until I get enough incentives to do it, I don't think I would make my life more complicated to save the equivalent of 7-10kg of cargo.
