The EPOMAKER TH108 JIS is a full-size wireless mechanical keyboard tailored for Japanese users.

The keyboard was released around 2025 (exact date not confirmed) and is priced at approximately ¥15,600. Warranty details follow manufacturer policy but are not explicitly stated. Accessories include a USB-C cable, keycap puller, and extra switches. Market positioning is mid-range: it offers premium features like hot-swap, gasket mount, and large battery at a competitive price point, making it an attractive option for Japanese users seeking a full-size wireless mechanical keyboard.

Best Use Cases

  1. Japanese office workers: The full-size JIS layout with numpad boosts productivity in document editing and spreadsheet work. Wireless connectivity reduces cable clutter, and the silent switch option makes it office-friendly. Not ideal for those who prefer compact or tenkeyless layouts.
  2. Gamers who enjoy customization: Hot-swappable sockets allow easy switch swapping, and RGB lighting is fully customizable. The gasket mount provides a comfortable typing experience during long gaming sessions. Competitive gamers may prefer wired mode for lowest latency.
  3. Multi-device users: Bluetooth pairing for up to 5 devices enables easy switching between PC, tablet, and smartphone. Perfect for users who want one keyboard for all devices. Mac users should note some key mapping differences.
  4. Quiet typists: The Sea Salt Silent switch option produces minimal noise, ideal for libraries, shared offices, or late-night use. However, those who prefer a pronounced tactile or clicky feel may find it too light.
