Shimose, born in Hiroshima Prefecture, graduated from Tokyo Imperial University and became one of Japan's earliest holders of a doctorate in engineering. In 1887, the Imperial Japanese Navy hired him as a chemical engineer, and from 1899 he headed a research unit tasked with developing a more powerful type of shell-filling for use by naval artillery. Shimose developed a new explosive based on picric acid – already used by France in the form of Melinite and by Britain in the form of Lyddite. Picric acid has an instability problem when in contact with iron or other heavy metals, so the French mixed it with collodion and the British mixed it with dinitrobenzene and vaseline to form compounds for stability within gun shells. On the other hand, Shimose coated the inside of a shell with unpigmented Japanese lacquer and further sealed it with wax to prevent his powder from comi ...
