What is GAKKEN?
Gakken Co., Ltd. (株式会社学習研究社 Kabushiki-gaisha Gakushū Kenkyū Sha?) (TYO: 9470) is a Japanese publishing company founded in 1947 by Hideto Furuoka, which also produces educational toys. Their annual sales is reported at ¥ 821 billion ($10 billion US).
Gakken is perhaps originally known for producing Denshi blocks and packaging them within electronic toy kits such as the Gakken EX-System, as far back as the 1970s. One of their original lines, the EX-150, was reissued in 2002, and was so popular as to inspire an expansion pack.
Gakken publishes educational books and magazines and produces other education- related products. For nursery school age children and their caretakers, they produce items such as child care and nursing guides. For school children, they publish text books, encyclopedias, and science books. Gakken also publishes educational magazines for high school students, as well as school guides for all levels. Gakken also provides products for playrooms, study rooms, computer rooms and science rooms.
Gakken also publishes general family-oriented and gender-oriented magazines in sports, music, art, history, animation, cooking, and puzzles.
Since 1993 Gakken has been publishing monthly logic puzzle magazines under the name Logic Paradise.
