This is innovative.
On August 25, 2025, at 1:00 p.m., KIBU Corporation (Saitama, Japan) will begin selling a Japanese-language kit exclusively for WOBKEY Crush80, which is sold by the company.

The selling price is 10,000 yen (tax included), and the board, key switches, and keycaps are already assembled.
Crush80 has a structure that does not use screws to secure the top and bottom cases, and the board and daughter board are connected by magnetic contacts called “pogo pins,” which can be easily replaced.
This replacement kit is perfect for those who have been looking for a high-quality Japanese keyboard.

Let’s take a look at the actual JIS-sequence pre-assembled set.
Contents include board (pre-assembled), 2 pieces of cushion foam, daughter board, and pins for floating mounting.

The keyswitch is Kailh Cocoa Linear, keycap printing is Dye-Sub (sublimation printing), and the material is PBT.
The cushion foam is in the form of two pieces stacked on top of each other, and one method is to remove the cushion foam if you want to emphasize the keystroke feeling more.


The board has a microcontroller but no USB port.
This magnetic contact called a “pogo pin” connects to the daughter board and integrates it with the case.

On the left is the daughter board that came with the unit, and on the right is the US layout.
At first glance, the colors may appear to be different, but the SN is reversed so that US and JIS are not attached.
Therefore, it is necessary to replace the daughter board.


I wonder if this place could have been made common.
Since you can easily enjoy the US↔︎JIS switch.
The firmware itself is installed in the microcontroller on the board side, so there should not be such a big problem.
I just don’t think the need for it is that great lol.
The top case is magnetic and can be easily removed.
After removing the US board, remove the six screws on the bottom with a Phillips screwdriver.

Remove the screws securing the board with an Allen wrench and refit.
Do not forget to detach the left and right battery connectors as well.

Completed refurbishment.
There is no difficult procedure.

When the daughter board is ready, attach the pins for floating mounting to the board set.

Naturally, the position is the same as the US board.

Compared to the US board, the appearance is largely unchanged except for the color of the board and the presence or absence of the logo.
After all, the Japanese are accustomed to seeing the ISO Enter key.


This is what it looks like when the case is inserted.

Unfortunately, the coloring of the key caps is not selectable.
As for the color, it looks like GoW, with cool gray printing on a white background.
This will match any case color.
The space bar size is 3.75u, which gives the impression that there are few replacement options even for Japanese-only keycaps.

This is unavoidable because there are few replacement keycaps for Japanese-language layouts to begin with.
From my research, 4.5u is the most common adoption, followed by 4.25u and 3.75u.

Half/full-width characters are “E/J”, conversion and non-conversion are symbols, etc., which is similar to the form used in Realforce and other products.


It’s cool.




Summary|If you want a high-quality aluminum Japanese keyboard, this is the one for you.

The above is a review of the Crush80 Japanese-language layout kit, which is now available from KIBU Shop.
Although the price of the main unit + Japanese conversion kit is a little high, it is the one and only choice for those who want a “high-quality aluminum keyboard with Japanese layout”.
It is also a true “buy” for those who already have a Crush80 and usually use Japanese keyboards frequently.
Recommendation.
