Japan using players who qualify via the residency rule or through relatives but born over seas to bolster their forward pack, is not HUGELY different to us using any player with tongan, samoan or fijian backgrounds..or UAE, Zimbabwe, New Guinea, New Zealand etc to bolster our own 'Aussie' stocks.
They got broadhurst, thompson, ives, mafi, tui, holani, wing & sau who could I suppose be classed as 'non japanese'...
We got Sio, TPN, Kepu, Pocock, genia, Quade, tomane, speight, palu, kuridrani, and folau.....not to mention naiyaravoro, maafu, faulkner, smith, cowan, timani, skelton, sautia, Fainga'a, Fainga'a, tapuai and betham who are all capped....Some were born here, some weren't.
So for example, why is Japan using Samoan BORN players different to us using Samoan BORN players....?
Is Hendrick Tui less Japanese then Henry Speight is Australian?
Kosei Ono moved to NZ at age 3!, played his footy at Christchurch Boys High.....does this make him a NZ import? Does this mean Japan can't produce flyhalves either?
