Venue ~ Opening

This was the first time I personally participated in Tenkey.

The venue for this event was the DMM.com Group Seminar Room on the 24th floor of the Sumitomo Fudosan Roppongi Grand Tower.

The overwhelming appearance of the building…

I never thought a keyboard event would be held at a place like this. (Honest Bass)

The venue is directly accessible from Roppongi 1-chome Station on the Tokyo Metro Namboku Line, so you do not have to go outside even once.

Exhibit: Tokyo Metro

At the entrance of the building, a staff member with an admission ticket was ushering me in, and I also received a ticket to enter the building.

Even though the doors opened at 12:30 p.m., the 24th floor venue already had a long line.

After the doors open, each person prepares his or her own “gems” at a table of his or her choice.

Those who had participated in the past had created their own keyboard recipe sheets, which they sandwiched between acrylic plates for easy display, brought in desk mats, and so on, with the same enthusiasm as at the ” key kettle.

Just after the appointed time, Tenkey opened with Yukari ( @eucalyn_), representative of moimate and organizer of Tenkey, as moderator.

The event was simultaneously streamed on Daihuku’s ( @Daihuku0015 ) YouTube channel, and the equipment brought in was the personal property of yuchi / Yuchi ( @F_YUUCHI ).

Cannonkeys is a select store for keyboard-related products based in the United States.

They are working to lower shipping costs to Japan and are expanding the number of eligible products as needed.

DSC 8801

Also at the exhibit booth was ai03, a designer and engineer with Cannonkeys.

The most notable is still the Atelier /Atelier-X series, which began GB on April 29, 2024.

DSC 8823

At the booth, prototypes and PCBs in an unpainted state were displayed, and many people were able to confirm the keystroke feel of the prototypes.

Also of note is the PHOTON, a 75% layout mechanical keyboard scheduled for release in late 2024.

DSC 8828

The new model, which has a plastic injection-molded body with a gasket-mounted structure, is said to “incorporate all the know-how we have accumulated in designing high-end keyboards,” and will be offered at an “affordable price” with a key feel, typing sound, and looks that one would not expect from a plastic chassis.

In addition, the wireless model will be compliant with Japanese technical regulations, and “PHOTON” will be popular worldwide in the second half of 2024.

Topre Corporation

At the booth of Topre Corporation, which mainly offers the REALFORCE series, a collaboration model with Hatsune Miku, an aluminum palm rest, and replacement keycaps were on display.

A dedicated keypad was also available for users to experience the difference in pressing pressure, and we got the impression that many people were checking out the capacitive non-contact keystroke feel.

Kawamura top RKawamura

Although photography was not allowed, there was also a display of replacement keycaps to be announced in the future. We expect that another coloring lineup will be added in the near future.

Diatech Corporation

DSC 8803

Diatech Corporation, the “pioneer” of the Japanese mechanical keyboard community that was the first to launch a keyboard using the Cherry MX axis, exhibited many of its FILCO brand products.

One of the most notable products was a keyboard stand with an integrated metal palm rest.

DSC 8842

The width is a typical 65%/75% keyboard size, which can be used for other products besides the company’s own.

I got the impression that this is a highly usable product that tilts to the perfect typing angle just by placing it on the table, and also serves as a wrist rest.

In addition, many people tried out the “Majestouch Xacro M10SP,” a left-right split keyboard that is very rare for a Japanese manufacturer.

Kawamura top RKawamura

The new Animal Free Leather Wristrest, scheduled for release in mid-May 2024, was also on display.

Yusha Kobo

Yusha Kobo, a keyboard specialty store that handles many self-made keyboard parts, is an official vendor of Altair released by Cannonkeys, and GB announcements and GB information on the Topre axis compatible “URSA Custom Keycap” for use with the Realforce and HHKB GB announcement and GB guide of “URSA Custom Keycap” compatible with Topre axes for Realforce and HHKB.

The booth exhibits included the Corne V4 series (designed by foostan), which went on sale in March 2024 and has become popular as a “soldering-free self-made keyboard,” and the company’s Primer series.

Lofree, an up-and-coming keyboard brand based in Shenzhen, introduced FLOW, a revolutionary evolution in the feel of low-profile mechanical keyboards, and Edge, currently crowdfunding on Kickstarter.

DSC 8805

Edge was on display especially for this event, and many people were able to see how it feels to hit the keys.

Kawamura top RKawamura

At only 5.8 mm at its thinnest point, Edge offers the feel of a mechanical keyboard, and we believe it is the best solution for switching from pantograph keyboards, which are currently the major type of keyboards.

PFU Corporation

DSC 8806

Many of you have probably heard of the Happy Hacking Keyboard name at least once.

PFU Corporation has added the HHKB Studio, an all-in-one device with trackpoint and gesture pad equipped with Cherry MX compatible key switches, to its previously released lineup of “capacitive non-contact” keyboards, and it has become It became a very hot topic.

Although we only sponsored the event and did not have a booth, I personally brought both machines to the exhibition.

moimate Inc.

moimate Inc., represented by Tenkey organizer Yukari-san, focused on exhibits such as ” CREATERPAD,” which raised 19 million yen in support on Makuake, and ” RUSHBOX,” which raised 20 million yen in support on Campfire.

The RUSHBOX is a gaming controller of the genre known as a lever-less acetyle controller.

The “high-end model” with aluminum housing weighs 1.2 kg and boasts excellent stability, even when operated on the lap, thanks in part to the non-slip pad on the back.

In addition, all keys are hot-swappable and can be replaced with compatible key switches of your choice, and unused keys can be blocked with key switch blockers.

In addition, the button assignments can be changed as desired, allowing for customization in accordance with tournament regulations.


This was the corporate booth section.

We hope this has given you an idea of what a very informative event this is.

Tenkey is not positioned as an event for so-called “enthusiasts,” but rather an event that can be casually attended by people with a broad interest in keyboards.

Kawamura top RKawamura

This was the first time for me to attend the event, and I felt very comfortable at a very intimate event.
