The proof is in the putting when it comes to zoysia putting greens, as explained in this new update on The R&A's Golf Course Management site.

Fine-bladed Zoysia matrella is utilized on hundreds of golf courses in East and Southeast Asia (and on some courses in the southern USA) as a putting green grass. Known as korai in Japanese, and as manilagrass in English, this species is especially well-adapted to low mowing heights in shaded areas. 

This video shows the most famous course in the world with korai greens – the Fuji Course at Kawana Hotel – and the ball roll on korai greens at Keya GC in Fukuoka.
