Japan (Nippon ...) needs to join the Six Nations (replacing Italy - initially). They may need to make some concessions in the beginning - like having an alternate base that is one regular flight from Japan (in Germany or France, etc) so home fans can make a one hop journey to be at the games. Because the travel for the Super competition is regarded as one very difficult factor that European clubs may want to avoid. An effort should be made because Japan plays with a great style that Rugby has lost - speedy, highly-skilled, fast-thinking players unlocking a defence.
