Japanese versions of Logitech MX keyboards and mice

Logitech goes by Logicool in Japan, and products named ロジクール are the official Japanese versions, with a warranty here in Japan. Search for the English name Logitech and a lot of what comes up is parallel imports (並行輸入).

The newest mouse is the MX Master 4, out in October 2025. It adds a vibrating sensor area under your thumb that brings up shortcut actions when you press it. The previous MX Master 3S is still on Amazon, with silent clicks and 8000 DPI. For everyday office work the two generations feel about the same, so the 3S is a pretty good deal when it's on sale.

The official Japanese MX Keys S has the Japanese JIS layout, with a big Enter key and extra conversion keys on both sides of the space bar. If you want an English layout, the official lineup has very few options, like the MX Keys S for Mac; otherwise you basically have to buy a parallel import.

The same color is sometimes listed under two model numbers, with one-year or two-year warranties and different prices. Check the warranty period on the product page before you order.
