Hello, this is Itsuki (@saigalog).

Many people may be interested in mechanical keyboards but feel that “Japanese layouts are limited” and “wireless options are restricted.”

The ” Epomaker TH87 JIS” reviewed this time is a model that fully addresses these concerns.

It features a practical configuration with a user-friendly tenkeyless size, a Japanese layout, and support for wired, Bluetooth, and 2.4GHz three-mode connections.

In this article, based on my actual experience, I will introduce in detail the typing feel, usability, and suitability for work purposes.

Typing Experience of the Epomaker TH87 JIS

The first thing I noticed when using the “Epomaker TH87 JIS” was the high level of completeness as a JIS layout.

The key arrangement feels natural, so anyone accustomed to a Japanese layout can start using it almost immediately without getting used to it.

The conversion/non-conversion keys and operations unique to Japanese input are also smooth, providing peace of mind for work use.

The keystroke feel is straightforward, balanced—not too light or too heavy.

Even during long typing sessions, fingers do not tire easily, and it doesn’t make excessive clacking, making it suitable for office use.

The texture of the PBT keycaps is also good, with a smooth touch.

The wireless connection is stable, and there were hardly any moments of noticeable delay in 2.4GHz mode.

Bluetooth allows switching between multiple devices, making it suitable for workflows moving between a PC and a tablet.

Hot-swap support makes it attractive because you can exchange switches and customize it in the future.

Being able to use it as-is at first and then adjust it to your preference once you get used to it is a pleasing point for a mechanical keyboard.
