Japanese ship-naming conventions
Traditional naming patterns in Japan
Japanese ship names follow different conventions from those typical in the West. Merchant ship names often contain the word maru at the end (meaning circle), while warships are never named after people, but rather after objects such as mountains, islands, weather phenomena, or animals.
Merchant ships
The word maru (丸; meaning "circle") is often attached to Japanese ship names. The first ship known to follow this practice was the Nippon Maru, flagship of daimyō Toyotomi Hideyoshi's 16th century fleet.
Several theories purport to explain this practice:
The most common is that ships were thought of as floating castles, and the word referred to the defensive "circles" or maru that protected the castle.
The suffix -maru is often applied to words representing something beloved, and sailors applied this suffix to their ships.
The term maru is used in divination and represents perfection or completeness, or the ship as "a small world of its own".
The myth of Hakudo Maru, a celestial being that came to earth and taught humans how to build ships. It is said that the name maru is attached to a ship to secure celestial protection for itself as it travels.
For the past few centuries, only non-warships bore the -maru ending.
