Fred Varcoe wrote about putting greens on Japanese golf courses in the August 2016 issue of Euro Biz Japan. The article, Know your greens (pdf, 3 MB), includes some quotes from me about bentgrass, korai, and how balls roll on putting greens.
For more about the two green system in Japan, see:
- The two green system
- Grass species and the two green system
- Golf course maintenance at Japan
- Not the usual everyday maintenance
- Golf in Japan, Mt. Fuji, and the two green system
And kind of on this same topic, but of more general interest, see Paul Jansen's post on The Japanese Golf Experience. You'll see more than just grass: breakfast beer, tiny hotel rooms, hot springs, cold springs, blue balls, green tea, and a volcanic eruption.
