Potter's books have been translated into nearly thirty languages, including Greek and Russian. "Tom Kitten" was released in braille by the Royal Institute for the Blind in 1921 and in the Initial Teaching Alphabet in 1965. The tale was translated and released in Dutch in 1946 as "Tom Het Poesje" and again in 1970 as "Het Verhaal van Poekie Poes". It was released in Danish in 1946 as "Tom Kitte", and in French in 1951 as "Toto le Minet". Twelve Potter titles including "The Tale of Tom Kitten" were under licence to Fukuinkan-Shoten of Tokyo, and released in Japanese in the 1970s. In 1986, MacDonald observed that the Potter books had become a traditional part of childhood in both English-speaking lands and those in which the books had been translated.
