Emperor Hirohito's affinity for the biological began in the sixth grade when he saw his first collection of marine specimens. This youthful interest marked the beginning of a lifetime of scientific investigations and contributions to the field of marine biology. Hirohito attended Gakushuin (then Peers School) and was tutored by the Special Institute established for the Crown Prince's education.

Hirohito was enthroned as Japan's 124th emperor in November 1928. The new emperor often collected specimens of the flora and fauna near the Misaki Marine Lab, in and around Sagami Bay, site of an imperial vacation villa. He built his own marine laboratory near a mulberry garden on the grounds of the Imperial Palace in Tokyo, employing two marine biologists and a specialist in flora to aid in the classification work. Hirohito worked in this laboratory to the end of his life. Over the years, more than 28,000 specimens of marine life were sent to him from all over the world for classification purposes.

After the war Hirohito published 32 books of plates, describing some 23 new species of ascidians, 7 new species of crabs, 8 new species of starfish, and 6 new species of pycnogonids. He conducted the first comprehensive survey of the biodiversity of Sagami Bay, but he was particularly well versed in the tiny tentacled polyps that grew on the sea floor, called hydrozoans. All of his work was published under the name 'Hirohito Emperor of Japan'.

In 1975, Emperor Hirohito visited the Woods Hole Oceanographic Institution, Woods Hole, Massachusetts and  talked with scientists there about a topic of marine biology that particularly interested him - marine hydrozoans. Some 40 species of the primitive animals are common in the Woods Hole area.  He was particularly interested in meeting Howard Sanders, who in his graduate studies at Yale University had discovered an animal that was not just a new species, but an entirely new phylum.
