Matsuyama Airport is about twenty minutes from the city by limousine bus and roughly forty from Dogo Onsen. Many visitors also arrive overland within Shikoku, linking Takamatsu or Tokushima.
Courses range from around 5,500 yards to full regulation length, which makes it easy to match your group. There is also a 27-hole club, so check the day's combination.
The Setouchi climate is dry enough that winter rounds are possible. The Kuma highland courses are a good summer escape but need a winter operations check.
Comparing a Japanese tee time on the headline green fee alone tends to produce a different number at the counter. Confirm whether cart, caddie or self play, lunch, locker and the local golf tax are included, then check rental clubs or shoes, minimum player counts, two-player supplements, payment method and whether overseas visitors can book. Clubs may also specify check-in times, dress codes and bathing etiquette, so submit player names accurately.
Fix two nights at Dogo Onsen, pair a city-area eighteen with Matsuyama Castle on day two, then play around Ozu or Kawauchi before the airport. Match your finish time to the ryokan dinner slot.
