Good Morning.  Please allow me to introduce myself.

I became interested in learning Japanese because I was interested in the robotics work being done by Honda and others, as well as the generally high level of technical and scientific information available in Japanese.  I have been studying Japanese for quite a while, and I have noticed that the number of excellent sites for learning online has been increasing, and the availability of good textbooks has improved as well. However, I have found very little in the way of learning more technical japanese, especially on the web. Although I am by no means fluent in Japanese, I still felt inspired to start this blog with hopes of assisting others with similar interests.  I plan to post twice a week with words and sentences related to a range of somewhat technical topics.

I welcome anyone’s corrections or additional explanations. I am also considering compiling a list of available resources for Japanese study, particularly more advanced material for self-studiers.  If you have any comments or suggestions, please let me know at account name: tj provider: technicaljapanese.com.
