On March 23, 2026, Keychron’s Japanese distributor, Kopec Japan, updated its official X to announce that it has newly started handling Keychron’s thin wireless keyboards, B3 Pro and B5 Pro, in Japan.
The B3 Pro is priced at 6,930 yen including tax, and the B5 Pro at 7,810 yen including tax.
Both are currently only available in English (US) layout and are offered in two colors: space gray and ivory white.
The B3 Pro is a 75% layout and the B5 Pro is a full-size, ultra-slim wireless keyboard.
Both support 2.4GHz wireless / Bluetooth / wired 3-mode connectivity, as well as web-based key remapping and macro configuration using the Keychron Launcher.
As for the B5 Pro, the product page also informs about its long battery life of up to 300 hours and 1000 Hz polling rate for 2.4 GHz connection.
With the start of this domestic distribution, Keychron’s line of thin and practical products has been further enhanced.
Keychron’s newly introduced B series is a product that uses scissor-style keyswitches, which is “unlike Keychron’s mechanical keyboards,” and is positioned by Greenkeys as a “product for beginners to keyboards.
Greenkeys OfficeAfter all, it is a high hurdle for a “light user” to suddenly purchase an expensive mechanical keyboard.
If that is the case, it will be easier to reach for a product that is affordable, looks good, and is just as easy to buy as a standard keyboard.
The decisive difference from other products is the “ability to change the keymap”.
In other words, this B series can be seen as “the first step to invite you to the keyboard swamp.
Keychron has a strong image of mechanical keyboards, but the selection has expanded to include thin wireless models that are easy to use in the office or for portable applications.
Compared to the existing B1 Pro, the circular keytops are very pretty.
They can be purchased at SUPER KOPEK andAmazon.
