Thanks, mjm!
Am looking for that sort of thing. But kids gaiters I can buy in Japan, or will ship from Japan to Japan.
I'm leaving London next week and would need to pick them up or have them delivered to Minato Ku (preferably to a Family Mart there) by the 9th April.

My request here, to the Japan forum, is anyone know the Japanese for, or where to buy (in Japan), or have a link to a Japanese source for, reasonably priced snake protection gaiters or leg coverings for kids?

Thank you.
