The Wordtank series is a line of Japanese electronic dictionaries manufactured by Canon. Although officially only sold in Japan, several of the multi-language models are popular among students of the Japanese language around the world. The ability to change menu display options to English on many of the Wordtank models is cited as a reason for the relatively wide foreign adoption. The ability to highlight an entire Japanese word (as opposed to just one character) and display a hiragana rendering of it is unique to the Wordtank series and is an extremely popular function for advanced learners. This function applies to all Wordtank models. One of the latest Wordtank models, the G70, offers this function for over 400,000 words.


Canon has been manufacturing electronic dictionaries with the "WordTank" name since the late 1980s. Some series were better than others for the non-Japanese user (the mid-nineties IDX series was more usable than models from five years later; later series around 2004-5 are again improved).
