Product Overview

The EPOMAKER TH87 JIS Japanese Layout TKL Wireless Gaming Keyboard is a tenkeyless (TKL) mechanical keyboard from EPOMAKER. It features a Japanese Industrial Standard (JIS) layout and supports three connection modes: 2.4GHz wireless, Bluetooth 5.0, and USB wired. The standout feature is its built-in 10000mAh battery, allowing extended wireless use without frequent charging. The keyboard comes with hot-swappable sockets, so you can change switches without soldering. It is equipped with linear Creamy Jade switches for smooth keystrokes and quiet operation. The gasket mount design absorbs typing impact, and the PBT keycaps offer durability and a premium feel. RGB backlighting adds a gaming aesthetic.

Key Features

  • Japanese (JIS) TKL layout — 91 keys in a compact form factor, saving desk space
  • Three connection modes — 2.4GHz wireless (USB dongle), Bluetooth 5.0, or USB wired
  • 10000mAh battery — provides weeks of use on a full charge (varies with backlight settings)
  • Hot-swappable sockets — compatible with 3-pin and 5-pin MX-style switches
  • Gasket mount structure — delivers a softer typing feel and reduces noise
  • PBT keycaps — resistant to wear and shine over time
  • RGB backlighting — multiple preset effects and custom settings
  • Windows and macOS compatible — keycaps include OS switch markings

Compatibility Guide

When connected via USB, the keyboard is recognized as a standard HID device, making it compatible with Windows PCs, Macs, Chromebooks, and game consoles (PS5, Xbox Series X/S, Nintendo Switch). Bluetooth mode supports pairing up to three devices, switchable via shortcut keys. The 2.4GHz wireless connection uses the included USB dongle for low-latency communication.

Note that the hot-swap sockets support 3-pin and 5-pin MX-compatible switches, but some specialty switches (e.g., Kailh Box, Gateron Low Profile) may not fit. Keycaps use a standard Cherry MX cross stem, so aftermarket keycaps are compatible.

Ideal Use Cases

  • Gamers who want more mouse space — TKL layout frees up desk area
  • Users who prefer a wireless setup — 2.4GHz mode offers low latency without cables
  • Enthusiasts who enjoy customization — hot-swap sockets make switch swapping easy
  • Those who need a Japanese layout — JIS layout is ideal for Japanese input
  • Heavy typists — gasket mount and PBT keycaps provide a comfortable typing experience

Upgrade Considerations

This keyboard is a complete product ready to use out of the box. If you plan to swap switches or keycaps, verify compatibility first. The hot-swap sockets have a current rating limit, so check manufacturer specs if using LED-integrated or specialty switches.

The battery is built-in and not user-replaceable. If battery degradation occurs over time, using the keyboard in wired mode is a practical alternative. Firmware updates may be available from the EPOMAKER official website, so check for the latest version periodically.
