Overview

The Razer BlackWidow V4 Low-profile Tenkeyless HyperSpeed JP is Razer's latest ultra-slim tenkeyless wireless gaming keyboard, measuring just 18.5mm in height. It features Razer's proprietary low-profile Yellow mechanical switches, which offer a quiet, linear feel with a 40g actuation force and a short 1.2mm actuation point for rapid keystrokes. Connectivity options include Razer HyperSpeed Wireless (2.4GHz) for lag-free gaming and Bluetooth 5.0 for multi-device convenience. The keyboard boasts an impressive battery life of up to 980 hours, and its aluminum top case adds both premium aesthetics and durability. This Japanese-layout (JIS) model is tailored for domestic users, complete with dedicated media controls and an AI prompt button.

Connectivity & Compatibility

The BlackWidow V4 Low-profile TKL HyperSpeed supports dual wireless modes: Razer HyperSpeed Wireless via the included USB-A dongle, and Bluetooth 5.0 for up to three paired devices. Switching between PC, tablet, and smartphone is seamless with dedicated Bluetooth buttons. It works with Windows 10 and later, as well as macOS. The Razer Synapse software enables full customization of key assignments, lighting effects, and macro programming. A standout feature is HyperSpeed Multi-Device support, allowing a compatible Razer mouse to share the same dongle, saving a USB port on your PC.

Product Info

Released in 2025, the Razer BlackWidow V4 Low-profile Tenkeyless HyperSpeed JP sits in the upper-mid-range segment of the gaming keyboard market. Despite its compact tenkeyless form, it packs 11 dedicated control buttons including a multi-function roller, media keys, battery status button, and an AI prompt button—rivaling full-size keyboards in functionality. The keyboard comes with a standard 2-year warranty (official Japanese distributor). The package includes the keyboard, USB-A HyperSpeed Wireless dongle, USB-A to C cable, USB dongle adapter, Razer logo sticker, and user manual. Pricing hovers around ¥28,880, making it competitive for a premium low-profile wireless gaming keyboard.

Best Use Cases

Competitive Gamers (FPS/TPS): The tenkeyless layout frees up mouse space, while the low-profile linear switches enable fast, quiet actuation. Ideal for extended gaming sessions without wrist fatigue. Multi-Device Professionals: Seamlessly switch between a desktop PC, laptop, and tablet via Bluetooth. The HyperSpeed dongle also pairs with a compatible Razer mouse for a clutter-free desk. Quiet-Environment Users: The linear Yellow switches are notably quiet, making this keyboard suitable for open-plan offices, shared rooms, or late-night gaming without disturbing others. Minimalist Desk Setup: Wireless connectivity and a compact footprint reduce cable clutter. The aluminum top case adds a sleek, premium look that complements modern workspaces. If you rely heavily on a numeric keypad for data entry or prefer hot-swappable switches for customization, this model may not be the best fit.
