This article covers Ninjutso Katana 軽量ゲーミングマウス.

Overview

The Ninjutso Katana is a wired symmetrical gaming mouse purpose-built for esports competition. Its standout feature is the 58g weight, achieved without any honeycomb holes thanks to a unibody shell that maintains excellent rigidity. The PixArt PMW3389 optical sensor delivers up to 16,000 DPI with an optimized 1mm lift-off distance, ensuring fast and precise tracking. Main clicks use Kailh GM8.0 switches rated for 80 million clicks, while the scroll wheel employs a TTC Gold encoder for crisp, tactile feedback. The flexible assassin paracord cable and 100% PTFE feet complete the package, providing a smooth, low-friction glide.

Connectivity & Compatibility

The Katana connects via a standard USB-A wired interface. It is plug-and-play, requiring no driver installation for basic functionality. Onboard memory allows you to save key bindings and macros directly to the mouse, making it easy to carry your settings between systems. It works with Windows, macOS, and Linux, so it's compatible with virtually any PC or laptop.

Product Info

Released around 2021, the Ninjutso Katana sits in the mid-to-high tier of wired gaming mice. Priced around ¥10,000–¥13,000, it offers excellent value given its 58g weight and PMW3389 sensor. The warranty is typically one year (check with the seller). The package includes only the mouse and a quick-start guide; no extra weights or accessories are included. It is widely available on Japan and other online retailers. The gold color variant is the most common.

Best Use Cases

First, competitive FPS and battle royale players will benefit from the low weight and responsive sensor, which reduce inertia and improve aim precision. Second, users who prefer symmetrical mice—the Katana's ambidextrous shape works well for both right- and left-handed users (though side buttons are on the left only). Third, enthusiasts who favor wired mice for zero latency and no battery concerns; the paracord cable is exceptionally flexible and feels nearly wireless when used with a mouse bungee. Overall, it's a strong choice for any gamer prioritizing weight and sensor performance.
