splitboard or snowshoes?

i know this questions sound dumb, and in part it is, but still...

all of my friends in japan have snowshoes, i rented em the past year, but this year i bought a splitboard. the point is i didn't try it yet, cause season is bad so far in italy, so even if i have a couple of weeks before leaving i will be pretty much new to skinning when i come to japan.

now the tradeoff: i found a cheap flight that has 20kg limit on baggages. with my reg board, my split, all the avi stuff, outerwear etc i'm pretty much overweight. So i could buy snowshoes, leave the split at home and go with the flow.

or, i could buy a more expensive flight ticket, and with the extra 3kg fit all my stuff with the split.

the difference in price is pretty much the cost of snowshoes.

so, besides all of this considerations, what you think is better for hiking in japanese conditions? and if i go with the split, i could have problems following the routes my friends with snowshoes will choose? this info could help my choice, not having tried to skin yet i really can't figure it out, and i heard it depends on conditions...
