In addition, the product lineup is also available in JIS (Japanese layout) for Japanese specifications, which is likely to be very popular.

JIS layout on Keychron K3 Pro

Now that the product is available from an authorized distributor, it is “Gikitei compliant” and can be used for wireless connection in Japan with peace of mind.
Of more interest, perhaps, is the JIS array lineup.
Like the regular Keychron K3, it has an irregular key layout with a horizontal row of arrow keys at the bottom right of the lowest row, but many Japanese will be very happy to be able to type with the same Japanese layout as a regular notebook computer.
- Supports QMK/VIA, so you can change to any keymap you like
- The US model features PBT double-shot keycaps for improved key feel. The engraving is dye-sublimation printing (Dye-Sub), so it is hard to erase.
- JIS models with JIS sequence models are laser-engraved on ABS
- Newly designed, deep-stroke “Gateron Low-Profile 2.0” key switches
- Wireless connection available
To purchase, please visit our online store.
We have not yet been able to confirm availability at actual stores, but it will probably be limited to a few stores in Akihabara where you can see and purchase the actual device.
The best places to purchase are direct sales sites or online stores such as Rakuten Ichiba.
