Other than the four majors, which are played outside Japan, there was one event played in Singapore and one event in South Korea. The SMBC Singapore Open was co-sanctioned by the Asian Tour. The Shinhan Donghae Open was co-sanctioned by the Asian Tour and the Korean Tour. The Zozo Championship was co-sanctioned by the PGA Tour (part of the 2019–20 PGA Tour season), the first ever such co-sanctioning.
