Yasaka Rakza 7 Hard Rubber Tested by Longtime Coach and Loyalist

Twelve years on the same rubber is a commitment most players never make. Coach Tsurusaki has, which is exactly why Yasaka tapped the veteran to put the new Rakza 7 Hard through a proper playtest on camera.

The demonstration video landed on the Takkyuya 840 YouTube channel on March 16, giving the table tennis community its first detailed look at how the harder variant of the beloved Rakza 7 performs in practice rather than on a spec sheet. Tsurusaki's long history with the original rubber makes the comparison unusually credible: a decade-plus of muscle memory with the standard Rakza 7 means any difference in feel, speed, or spin response registers immediately in his hands in ways a first-time tester simply couldn't detect.

The Rakza 7 has built a loyal following over the years as a rubber that balances speed and control in the mid-range, popular with all-round attackers who want gears without sacrificing consistency. A harder sponge variant typically pushes the speed ceiling up while demanding more precise contact, which is the central question hanging over any Rakza 7 Hard review: does it keep the character of the original, or does it become a different animal entirely?

Tsurusaki's twelve-year baseline makes that question answerable in a way most factory demos cannot. The Takkyuya 840 channel has built an audience around exactly this kind of in-depth rubber and blade content, and framing the playtest around a coach with documented long-term loyalty to the parent rubber is a smart editorial choice. The result is a test that serves both the curious newcomer and the seasoned Rakza faithful weighing whether to make the switch.
