The Hiroshima Peace Memorial, now internationally recognized as the A-Bomb Dome, stands as the most enduring project completed by Jan Letzel. Originally constructed as the Hiroshima Products Exhibition Hall, the structure serves as a primary example of his architectural contributions during his career in early 20th-century Japan, where he relocated to influence the built environment of the region.
Early Education and Professional Beginnings
Born in 1880 in Náchod, Bohemia, Letzel was the son of hotel owners Jan and Walburga Letzel. His technical education began at the Higher Vocational School, where he completed training in the construction department in 1899. He later served as an assistant in the Department of Civil Engineering at the State Industrial School in Pardubice. In 1901, he entered the School of Applied Arts in Prague, receiving three years of instruction under Jan Kotěra. Before his departure for Japan, he gained practical experience at the Quido Bělský architectural firm and designed Art Nouveau structures in Mšené-lázně.

Letzel arrived in Tokyo in June 1907 to work for a French architectural firm. By 1910, he and his partner Karel Hora established an independent office. Over the following years, he executed approximately 40 designs, including the German embassy, the Jesuit College, and the Sacre Coeur French school in Tokyo. His work introduced significant scale to cities like Hiroshima, where traditional construction consisted primarily of two-story wooden buildings. The administrative building for the Japanese Chamber of Commerce and Industry became his most prominent landmark.
Diplomatic Service and Later Years
Following the departure of Karel Hora for Bohemia in 1913, Letzel operated the firm alone until 1915, when World War I forced him to cease activities. With the emergence of Czechoslovakia as an independent state, he transitioned into diplomacy, serving as a commercial attaché at the Czechoslovak embassy in Tokyo starting in 1919. He returned to his home country in 1920 but soon resumed his attaché duties in Japan. He witnessed the destruction of numerous projects during the 1923 Great Kantō earthquake, an event that led to his return to Prague in November 1923. He died in 1925 at the age of 45.
