dental floss in japan?

I use oral-b dental floss, but it's not available here in Japan?
Can someone recommend a good brand?
I did try several brands, but found it doesn't fit into tight spaces between teeth.

when i was here 6 months ago i bought dental floss in tokyo. an orange coloured box.

i cant recall if it was oral-b but i did use oral-b before, and i didnt really notice a difference with the japanese one.

Orange box, i think blue outer packaging from a regular parmacist/drugstore, the kind that sells shower gel and stuff.
