Ayaka (black jacket) and Kyoka Matsumori were the first JLPGA sisters to finish in the top-3 of the same tournament, which was last week. Two translators of the above article quoted Kyoka saying she takes a bath with Ayaka every day. It's a cultural thing, I assume. Maybe that's what the two Rockets are missing.
I just had to look up Kotone Hori's apparel brand. It's called Admiral Golf, an offshoot of the soccer brand Admiral in England, which explains her British preppy look. Hori has been with Admiral Golf since her 2015 JLPGA rookie season. Website:
