Genection
Nittaku's top-tier rubber, with a newly developed dual sponge improving energy efficiency by around 11% to deliver powerful drives and excellent control together.
About this product
The fastest of the 16 Nittaku rubbers here at 16.5, and the most expensive at ₩138,000.
Its hardness of 42.5 (German 52.5) is at the firm end of the range, and the pairing matters: a hard sponge only returns energy once it has been fully compressed. Without the swing to do that, 16.5 stays theoretical.
Spin of 13.5 is high but not the highest. Nittaku’s own Hurricane 3 reaches 14.5 for less than half the price — though that is a tacky rubber and an entirely different proposition.
₩138,000 is at the top of the rubber range on this site. It earns that only for a player already swinging fast and pushing the limits of tensor rubber. Before that stage the money is wasted.
What the numbers say
Inverted, 42.5° (52.5° German scale) sponge. Its speed of 10.0 ranks 1 of 23 rubbers, among the very highest. The other axes sit at a similar level, so the profile is well balanced. Based on the manufacturer’s published figures.

Where this rubber sits among Nittaku inverted rubbers
Speed and spin figures Nittaku publishes for 14 of its inverted rubbers. Nittaku does not state a maximum, so read this as relative position within the family. Further right is faster; higher means more spin. Other brands use different scales and are not mixed in.
