Interesting but ----- If I'm not mistaken, 892 Yen is around $11.50! That's quite steep for a plug.
Furthermore, since I've been using 4 stroke engines (around 12 years), I've come to a conclusion about the various plugs: I cannot tell the difference.
I have ten year old SAITOs that still run with their original plug. I have no idea what brand they are but they just keep working.
Anyone here had similar experiences?

Once ran a Magnum .72 4 stroke inverted and found that my usual OS F plug wasn't hot enough to keep it running reliably. Switched to the Thunderbolt 4 stroke plug -- as recommended by Magnum -- and it ran fine. The Magnum is no Saito for sure, but in this case the plug mattered. Enya certainly is proud of the new plug. Don't think I'll rush out and order one any time soon at twice the price of others.

Been running Saito four strokes for 4 or 5 years and have yet have had a bad plug. After break in I install a new OS-F and can't recall ever having to replace one. However I don't fly as often as most so my experience may not be a good one to go by.

I have been using the OS 70 Ultimate and it has very high compression, in the ground I get pre ignition, in the air no pre ignition, meaning I am right on the limit as far compression ratio is concern. The OS F plug last for about 100..120 flights, after 70 flights I can feel the power going a bit down til I have to replace it for good.
Any way, it is a new plug for our engines. If it is going to be better or worse I do not know...I am just sharing the information.
As far as I can tell Enya plugs for 2S are superior then other brands I have tested OS, T.Bolt, Fox, Fireball, McCoy.. So I will certaingly try one on my 4S engine.
I bet it will last longer then other plugs and at the end it will cost less.
