任天堂 / Nintendo

 I actually never knew that Nintendo was also written in Japanese, which actually would make sense as it's a Japanese company. It's just that I'm so used to seeing the romaji "Nintendo" logo that I was a bit surprised when my Japanese teacher showed that it could be written as 任天堂.

I attached some images of the various logos that have been used throughout the years, including a recent one written as "Nintendo switch" in Japanese.
