If they do, it might just be a matter of finding a distributor willing to handle it in other parts of the world.
Just on a point of information, Fuji did at one point make Neopan 400 in 220 as it was listed in their UK professional catalogue but hasn't been listed for several years. I've no idea if it's still available in Japan. Konica still do some colour neg professional films in 220 but they don't seem to be on the UK market but are listed on the English part of their main website.
