For the tochigi belts, what would be the recco for someone like me wearing pants with a 35.5IN waist? I'm on the tail end of a large and the front end of an XL (I also have problem finding japanese pants too...but I digress...)
I'm about there. I would recommend going XL and cutting it as per the numerous videos's and instructions on the relevant threads.
You'll be able to wear the L but may find it annoying only being able to use the first two holes.
