Did you know...?
What does the abbreviation "TDK" stand for?
The name is taken from the initial letters of the three Japanese words "Tokyo Denki Kagaku" ("Tokyo Electrochemical") when written in the Roman alphabet.
Because the company name is not in Japanese script, this may not be immediately evident, but the company was actually founded in Japan in 1935. At first, the company was known by its Japanese name "Tokyo Denki Kagaku Kogyo" ("namely Tokyo Electric and Chemical Industries"), but this was simplified into the acronym TDK that has been used since 1983. In Japan, TDK was the first company listed on the stock market to use a name in Western script. Nowadays, TDK is active in some 130 countries around the world. Its easy to remember three-letter name may have helped it gain acceptance on the global stage as well.
