The Early Years and the Rise of the Encyclopedia
Heibonsha began as a vehicle for Shimonaka Yasaburō to sell his pocket encyclopedia, That is Convenient: Pocket Advisor. By 1923, the business transitioned into a public limited company. The aftermath of the 1923 Great Kantō earthquake served as a catalyst for the company to expand its publishing scale significantly.
In 1927, the house introduced the 60-volume Collection of Contemporary Popular Literature. These budget-friendly, small-format books became widely known as "one-yen books." This success paved the way for the first major Encyclopedia, a 28-volume set published between 1928 and 1934.
The Monumental Daijiten
Between 1934 and 1936, Heibonsha published the Daijiten (Great/Comprehensive Dictionary), edited by Shimonaka Yasaburō. This work remains the largest kokugo dictionary ever published. The original 26-volume edition featured over 700,000 headwords organized by pronunciation, covering an expansive range of Japanese vocabulary.
Post-War Expansion and Diversification
Although operations ceased during the 1940s, Heibonsha relaunched in 1945 by reprinting its 1934 Encyclopedia. The following decade marked a period of rapid growth, with the publication of specialized works including the Social Encyclopedia, Housekeeping, Complete Collection of World Art, Encyclopedia of World History, and the Children's Encyclopedia.
To mark its 40th anniversary from 1954 to 1959, the company issued a comprehensive 32-volume World Encyclopedia.

Modern Era and Specialized Series
The 1960s and 70s saw Heibonsha venture into new formats. In 1961, the National Encyclopedia was released during a period of high demand for encyclopedic knowledge. In 1963, the company innovated with Sun, the first monthly graphics magazine in Japan. They also established the Eastern Library Series to showcase Far East literature.
Collaboration became a key strategy in the 1970s. Heibonsha partnered with the U.S.-based publisher Weatherhill to produce The Heibonsha Survey of Japanese Art, featuring bilingual text in Japanese and English. Additionally, the company began the 50-volume Japanese Historical Place Names gazetteer in 1979, which has since transitioned to an online format featuring 200,000 detailed headings as of 2022.
Corporate Evolution and Recent History
In 1980, the internal Japanese Map Research Institute was spun off into the Heibonsha Map Publishing imprint. The company continued its commitment to massive reference works, completing a 35-volume World Encyclopedia in 1988. Later additions to their catalog include the Heibonsha Library (1993) and Corona Books (1994).
In recent years, Heibonsha launched the magazine Heart (2011) and relocated its offices to the historic publishing district of Kanda-Jimbochō in 2012, celebrating its centenary in 2014.
