† Japan's share of the quota distribution from the Top 32 shuffle is likely to shuffle back to the Rest of World first.
Quotas can then shift from one region to another based on responses received by the WRC staff from various organizations and individuals. As of July 10, 2017, Japan has filled 80 seats with 16 of their 20 berths awarded from WRC2014.
