Japanese terms related to using a computer

The following terms will probably only be of use to people who frequently write code or who are involved with software development in some other way. Again, most of the Japanese words are simply borrowed from English, so remembering them shouldn’t be too difficult. For the ones that aren’t, don’t get too stressed out. You’ll learn them soon enough, and there’s even a good chance that your Japanese coworkers will be able to understand the English versions of the words, anyway. Still, it’s best to study up so you can follow along at meetings, etc.

I live next to the beach in Kanagawa Prefecture, an hour away from Tokyo. I love living in Japan and am eager to share my experiences related to living and working here. In my free time, I enjoy bouldering, surfing, reading, eating, and cooking Japanese food.
