There could be some pretty significant changes coming to the Japanese player market:
For years, cashed-up clubs in Japan have raided Australia, New Zealand and the Pacific Islands for stars. But the numbers of players being poached may soon dry up.

Article talks about a requirement of 8 players of "Japanese blood"
in match day squads on the field at anytime - that's not just qualified or capped, but ethnically Japanese, with a 30+ cap exception for naturalised foreigners.
Not sure how I feel about it, would be very good for Australia, particularly in holding on to younger talent and super rugby level players (the stars will still be sort after, maybe even more so), but it's seems really punitive to those players who've already made the jump. Not to mention the discomfort I have introducing race/ethnicity into the mix, rather than just nationality.
I'm not so sure this will be a huge help to Japanese rugby either, you'd assume it will mean more local players are produced eventually, but the shock of the changeover may see the national team fall right back in the rankings at a time they should be trying to assert themselves. It could also really hurt the prospect of a crossover comp with super if there is a significant decline in the quality of league one sides as a result.
