Design Review

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.

A keyboard with such a physical logo on it means it's EXPENSIVE. Also, here you can see the quality of the keycap labels. Probably by a process called Dye Sublimation, a very expensive process. The label will NEVER rub out because it's part of the plastic. (img by webwit)

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.

[see TRON Keyboard]

To understand Japanese input methods and what does TRON mode do, see:
