Tombow

The company was established in 1913, when Harunosuke Ogawa opened a shop in Asakusa, with the name "Harunosuke Ogawa Pencil". One year later, the Mason brand of pencil was released. That was followed by other products, named "Stick", "Submarine" (1915), "Kaiman Roro", and "Cabinet" (in 1916).

The dragonfly figure ("Tonbo" in Japanese – トンボ) was registered by the company as trademark for its pencils in 1927. During the following years, Tombow continued launching new lines of pencils. In December 1939, Harunosuke Ogawa Shoten incorporated as two companies, Tombow Pencil Manufacturing Co., Ltd. (manufacturing) and Tombow Pencil Trade Co. Ltd. (sales). The company launched an eraser manufactured by fats and oils without using rubber.

In 1946, the company added pencil sharpeners to its catalog of products. In 1954, the company relocated the headquarters from Taitō to Nihonbashi in Chūō, Tokyo, with expansion of business. Four years later, the first ballpoint pens and markers were released, which consolidated Tombow as a manufacturer of all types of writing implements. In 1962, the company released an electric pencil sharpener. In November 1968, the Tombow pencil head office was moved to Kita, Tokyo, where it still remains.

The Tombow Ballpen Co., division, was established in 1973. The company established its first European location in 1980, in Cologne, Germany, the "Tombow Pen & Pencil GmbH". International operations expanded to the United States (1983 in Westlake Village, California), Thailand (1990 in Bangkok), Vietnam (2003), and China (2011).
