The King George V Gensuitō: An Imperial Japanese rarity in the Royal Collection

In 1918, a Marshal’s sword (Gensuitō) was introduced into the Japanese honours system, to be presented to specially recognised admirals and generals of the Imperial Japanese military who had been awarded the honorific title of Gensui. Later that year, a very fine example of such a sword was presented to King George V at Buckingham Palace, on behalf of Emperor Taishō. These swords were made to the highest standards by master swordsmiths, with no more than 24 produced before the abolishment of the rank of Gensui in 1945. Very little has been written about Gensuitō in Japanese, much less in English. The King George V Gensuitō, today held in the Royal Collection, is recognised for its aesthetic value, but has been the subject of only limited scholarship. Drawing on primary sources held in the Royal Collection, Royal Archives, and National Archives of Japan, as well as secondary sources published in limited-circulation journals that have not been digitised, the author presents herein an overview of this important Gensuitō—believed to be the sole example held in a collection outside of Japan.
