During the occupation, at the request of General Douglas MacArthur, he was recruited by Commandant Charles McDowell to work at the Tokyo Army College.
MacArthur would join Greta Garbo, Pope Pius XII and Queen Elizabeth II, as a prominent collector of Jacoulet's work.
The earliest book about him was written during his lifetime (Florence Wells (1957) Paul Jacoulet: Wood-Block Artist) and includes the original desperation prices for which he sold his work at that time.
Jacoulet was a true renaissance man: French but born and raised in Japan, expert in Kabuki, proficient on traditional Japanese musical instruments, a good calligrapher, conversant in several languages, and a recognized butterfly collector.
Although his most valued works are from this part of the world, he also has a substantial number of prints with subjects from China, Korea, all areas of Japan, and Mongolia.
Second, some of the subjects who posed for Jacoulet are still alive and they are currently being interviewed by a professor in Guam (Donald Rubinstein) to learn more about his artistic process.
Jean MacArthur, Douglas's wife, received an annual Christmas gift and his work hung in the General's headquarters in Tokyo and later at the Waldorf-Astoria.
