Yasaka Rakza 9

The correct name is Yasaka Rakza 9. It is an inverted table-tennis rubber, not a rubber ball or a fabric-layered product.

Rakza 9 is tuned for faster rebound and a lower, more direct trajectory than Rakza 7. Yasaka describes it as a speed-priority option for aggressive drives while retaining the grippy Rakza topsheet concept.

Yasaka lists a medium-hard range of roughly 40 to 45 degrees, often summarized as about 42.5 degrees. That gives it a crisper response than softer rubbers intended primarily for control.

Yasaka is a Japanese brand, but its official Japanese listing identifies Germany as Rakza 9's country of manufacture. It uses the brand's Hybrid Energy design and is sold in several sponge thicknesses.
