Japanese Input Layout M-type, TRON, Stickney Next, JIS Standard

Esrille also supports several Japanese input layouts, including M-type and TRON.

The M-type and TRON are interesting, because they are efficiency based, similar to the design principle of Dvorak, but for inputting Japanese. 〔►see Alternative Keyboard Layouts

M-type is designed mostly for using English alphabets to type Japanese.

TRON is typing Japanese phonetic alphabets directly.

Here's a review by jbm.

I have an Esrille NISSE and love it. I've been using it full time (6-10 hours a day, 5-6 days a week) since .

Side note: I believe I was actually the first person in the US to order one. It was before they were able to ship assembled boards internationally, so I ordered it as a kit and assembled it myself. I forget where I first saw it — maybe Xah Lee's blog - but the design was immediately appealing to me.

The other ergo boards I've used extensively are the Ergodox and Truly Ergonomic Keyboard. I like them all but the Esrille has been the best fit by a wide margin.

The things I like about all three are:

What I like about the Esrille above the other two:

Subjectively, I can tell you the Esrille is definitely the most comfortable for me. I used to experience some level of discomfort 1-3 out of most weeks, despite fairly good technique, regular exercise, breaks every couple hours, etc. I honestly don't remember the last time I experienced any discomfort typing since switching to the Esrille.

This is less important, since it's something you can always change, but I'll also mention that I've been very happy with the default layout on the Esrille, including the function layer. I fully expected to reconfigure things, just because I usually would, but in practice there hasn't been anything I've wanted to mess with.

As I'm sure you can tell, I'm a big fan, and would be very comfortable recommending it :)

Let me know if you have any questions about it — I'll be happy to answer any I can.
