Overview

The Buffalo BSKBU115BK is a standard wired full-size keyboard built around a 109-key Japanese (JIS) layout. Because it includes a dedicated numeric keypad, spreadsheet work and data entry stay on the home row rather than reaching for a separate pad. The USB Type-A wired connection means no receivers, no batteries, and no pairing steps to worry about.
Typing feel comes from a membrane design in which rubber domes support the key tops, paired with a 19mm key pitch and a fairly deep stroke. The area around the spacebar is widened so your thumbs rest comfortably, and an angle-adjustment stand helps you settle into a workable posture over long sessions. It sits in the entry-level price band, which makes it an easy pick as a first external keyboard or a spare.

Connectivity & Compatibility

Connection is wired USB Type-A. No driver installation is required, so plugging the cable into a USB Type-A port on your PC is enough to start typing. The cable runs roughly 1.5m, which gives you room to route it from a rear port on a desktop tower.
The layout is Japanese JIS with 109 keys, including the numeric keypad in a full-size arrangement. Any PC with a USB Type-A port is the intended host. There is no wireless or Bluetooth option here, so anyone who wants to hop between several devices should look elsewhere.

Product Info

It launched on July 29, 2026 and sits in the entry tier at a price in the low four figures in yen. The formula is deliberately plain: full-size with a numpad, Japanese layout, wired connection, and nothing extra layered on top. That separates it from premium boards that sell on quietness or customization, and it suits people who simply want dependable input at low cost.

Best Use Cases

  • Office workers who type numbers all day in spreadsheets or accounting tools: the separate numeric keypad and JIS layout keep entry efficient, though the wired full-size body is not something you would carry around.
  • Anyone whose bundled desktop keyboard died or who wants a spare on hand: plugging into USB Type-A is all it takes, and the price stays low, but people who care about key feel or silence will want more.
  • Households adding input to a shared or secondary PC: there is nothing to configure, so family members of any age can use it immediately, while multi-device wireless switching is out of scope.
