The μTRON Keyboard (aka microTRON, muTRON, uTRON.) is from Japan, came out in 2007.
μTRON Keyboard is discontinued since .
The μTRON keyboard is a modern version of the TRON keyboard of Japan.

Total Key Count
Total key count: 76.
Each side has: 6 columns * 4 rows + 5 + bottom 9 = 38.
This is a excellent design. The only design issue i found is that it doesn't have dedicated function keys. The function keys are merged with the number keys. However, the other quality design makes up for it.
- For why the μTRON is a excellent design, see: Computer Keyboard Design Flaws.
- For why dedicated function is important, see: Function Keys in Computer Keyboard.
μTRON Keyboard Layout
μTRON keyboard has 2 modes. Normal mode, and the TRON mode.
Normal mode is using standard JIS input method. (which is very inefficient.)
TRON mode is based on the TRON keyboard, a very efficient input method for Japanese.

μTRON vs Happy Hacking
μTRON compared with Happy Hacking (HHKB) Keyboard.
The μTRON's keys are smaller. Note that, the width of four keys (ASDF) on HHKB measures 7.5 cm, but 6.8 cm on the μTRON.
The key switch mechanism is Topre switch, which is even better than the famed Cherry MX switches. [see Guide to Keyboard Key Switch Mechanisms]
