Glossary of Japanese Boats and Terms

[Updated 6/26/22]

This is a list of terms relating to traditional Japanese boats, or wasen, that I’ve collected in my notes. This is not even close to being a comprehensive list, and the descriptions given are really quite basic. I’ve compiled this list from my own studies, and with the help of many others who are more knowledgeable than myself.

Yubune 湯船 - a bath boat from the Edo period.

Yubune 湯船 – a bath boat from the Edo period.

Sources of information include the book Funakagami, books I’ve collected by Professor Kenji Ishii, the works of Douglas Brooks, information parsed from the Internet, and information I’ve gathered personally through visits to the Toba Seafolk Museum, the Urayasu Museum, the Edo Tokyo Museum, and the Ogi Folk Museum.

At some point, I hope to write more complete and detailed descriptions for each of the terms. Probably, this will happen one term at a time, as I learn about each one and study them in more depth. However, the list of boat types seems endless, and I have only a small number listed here. I have many more that are not in this list, so I will expand it over time.

I’ve grouped these terms in a way that seems most meaningful to me. I’ve sorted alphabetically where possible, but, more importantly, in order or relevance. Note that this page is under construction and will be revised as time permits.

For the boat types and general terms, I’ve tried to include the terms written in kanji (chinese characters adopted for the Japanese language). However, in many cases, I’ve only found the names written in katakana (one of two phonetic alphabets used in Japanese). Boatbuilding terms, in particular, seem most commonly written using katakana.

I include the Japanese text in order to make it easier to search the web for images and information. Simply copy the characters and past them into your web searches and you’ll find a lot more than simply using the romanized words.
