Sorry, this is actually a six-month old interview content.

On May 4, 2025, the 8th annual ” Tenkaichi Keyboard Waiwai Kai Vol. 8 ” was held.

The location is the same as last time, Sumitomo Fudosan Roppongi Grand Tower 24FDMM.com Group Seminar Room in Roppongi.

We are six months late, but let’s review the previous trends before Tenkey Vol. 9.

Tenkey Vol. 8 Report|”Trackball-equipped” keyboards are popular?

My first impression of Tenkey this time was that there are so many more “with trackball” keyboards.

The left-right split thumb operation style (the so-called Keyball style) and the integrated keyboard with a center lab, which seems to be the origin of Aki’s keyboard, were very common.

miscellaneous impressions

The truth is that since my last coverage of Tenkey, I myself have been overheated by the number of units on display and have not updated this page.

I am very happy that the event is getting bigger and more people are participating, but……lol.

I have been trying to be as “comprehensive” as possible in taking photos and introducing them, but it is becoming impossible.

(Probably more than 1,000 keyboards brought in)

The next coverage is expected to be a pick-up spotlight.

If anyone at the event says, “Look at this keyboard! Please let us know if you see any of these keyboards at the event!

See you at Tenkey Vol. 9.
