You'll happily drop 200,000 or 300,000 yen on a PC, yet somehow settle for whatever mouse came in the box, or grab the cheapest one off the bargain bin. This is like a professional chef working with a 100-yen-shop kitchen knife.
Your mouse is the one and only "point of contact" that translates your thoughts into the digital world. Its precision, the feel of its clicks, and the speed of its scrolling all translate directly into your productivity.
Today we're introducing the device revered worldwide by creators and engineers alike as the "undisputed king of mice" — Logitech's flagship model, the MX Master 3S. It runs about 16,000 yen. You might balk at "over 10,000 yen for a mouse?" — but once you've experienced this level of comfort, you'll never go back to a flimsy plastic mouse again.

This mouse's signature feature, and its greatest weapon, is the metal "MagSpeed Electromagnetic Scroll Wheel."
Turn it slowly with your finger and you'll feel a precise, ratcheted "click-click-click" resistance. But flick it with momentum and the resistance suddenly vanishes — it spins on silently, like a fidget spinner, with a smooth "whoooosh."
This enables scrolling at up to 1,000 lines per second. Whether it's an Excel sheet thousands of rows deep or the bottom of an endlessly long web page, you arrive instantly. The tiny lost moments of "scroll, then wait" are reduced to zero. It's a sensation that becomes addictive the moment you try it.
| Click Noise Cut by 90%, With a Richer Feel

Its predecessor, the MX Master 3, was already a near-perfect mouse, but its one weak point was the loud "click-clack" of its buttons. In a quiet office, or at home late at night with family asleep, the volume was just enough to make you self-conscious.
The latest "3S" model, however, finally adopts "Silent Clicks." Click noise is reduced by 90%, achieving a level of quietness you have to strain to hear at all.
What's wonderful is that the sound has been muted without sacrificing the tactile feel. Instead of a mushy, spongy sensation, your finger receives an elegant, satisfying "tock, tock" of feedback. As a result, even rapid-clicking during a Zoom meeting won't transmit noise through your microphone.

"My mouse won't move on this café glass tabletop." That frustration is a thing of the past. The sensor resolution has been boosted to 8,000 DPI, tracking accurately even on transparent glass without a mousepad.
And let's not forget the "thumb wheel" on the side. Turning it lets you smoothly perform "horizontal scrolling" in Excel or "timeline navigation" in video editing. No more dragging that scrollbar at the bottom of the screen.
What's more, with the dedicated app you can freely customize what each button does on a per-app basis — "change brush size in Photoshop," "switch tabs in your browser," and so on. It truly becomes a tool that moves like an extension of your own hand.
| From Excel Power-Users to Creators

This mouse is made for everyone who "creates something" on a PC.
- Engineers and accountants wrestling with massive spreadsheets and codebases
- Creators who rely heavily on horizontal scrolling for video and image editing
- Long-hours workers looking to prevent wrist fatigue (and tendonitis)
- Anyone who wants to move between multiple PCs (Windows/Mac) with a single mouse
In particular, its distinctive ergonomic shape is engineered to cradle your hand at a natural angle, dramatically reducing wrist strain even over long work sessions.

The MX Master 3S is more than just a mouse. It's an engine that accelerates your work, and a support system that lightens the load on your body.
A tool you'll touch eight hours a day — over 2,000 hours a year. A little over 10,000 yen invested in something like that is hardly an expensive purchase. The key to transforming your desk work from "drudgery" into "comfortable piloting" lies right here.
