How Japanese words travelled into English
Borrowing happened in waves. When Japan opened to Western trade and diplomacy in the mid-nineteenth century, titles and objects entered English. Soldiers stationed in Japan and Korea after the Second World War carried back casual words, and later decades brought food, craft, business and pop culture vocabulary.
Each wave borrowed a word for the specific thing English speakers met, which is why many of these words have a narrower meaning in English than in Japanese.
Words that arrived through diplomats and soldiers
These are the words most people do not realise are Japanese at all, because they have been fully absorbed into English.
| Japanese | Romaji | Meaning |
|---|---|---|
| 大君 | taikun | Great lord: a title used for the shogun in dealings with foreign powers, which became tycoon |
| 班長 | hanchō | Squad or group leader, which became honcho |
| 少し | sukoshi | A little, which became the slang skosh |
| 人力車 | jinrikisha | Human-powered vehicle, which became rickshaw |
Tycoon started as a title for Japan's ruler in diplomatic contexts and later shifted to mean a powerful businessperson. Hanchō is still an everyday Japanese word for the leader of a small group or team.
Culture, craft and home
Many borrowed words are compounds whose parts are transparent in Japanese. Knowing the parts helps you remember them and shows how Japanese builds vocabulary.
| Japanese | Romaji | Meaning |
|---|---|---|
| 津波 | tsunami | Harbour wave: tsu means harbour and nami means wave |
| 折り紙 | origami | Folded paper: ori from folding and kami, paper |
| 盆栽 | bonsai | Tray planting: a tree grown in a shallow container |
| 布団 | futon | Bedding laid on the floor and folded away in the day |
| 絵文字 | emoji | Picture character: e is picture and moji is character |
| カラオケ | karaoke | Empty orchestra: kara is empty and oke is short for orchestra |
Food words and how they shifted
Umami was named in 1908 by the chemist Kikunae Ikeda, who identified the savoury taste of kombu broth. Today it is a standard term in food science in many languages.
Other food words kept their core meaning but lost the Japanese long vowels, which is one reason English speakers pronounce them differently.
| Japanese | Romaji | Meaning |
|---|---|---|
| うま味 | umami | Savoury taste |
| ラーメン | rāmen | Ramen, with a long a in Japanese |
| 豆腐 | tōfu | Tofu, with a long o in Japanese |
| お酒 | osake | Alcoholic drinks in general, or rice wine |
| 日本酒 | nihonshu | Japanese rice wine specifically |
Words whose meaning narrowed in English
The biggest surprises are words that mean something broad in Japanese and something specific in English. Using the English sense in Japan can lead to small misunderstandings.
| Word | In English | In Japanese |
|---|---|---|
| Anime | Japanese-style animation | Any animation, including Western cartoons |
| Manga | Japanese comics | Any comics, wherever they are from |
| Kaizen | A management philosophy of continuous improvement | The ordinary word for improvement |
| Sake | Japanese rice wine | Alcohol in general, as well as rice wine |
| Futon | A sofa bed or thick mattress | Thin bedding laid on the floor |
| Sudoku | A number puzzle | A puzzle name trademarked by one publisher; others use different names |
Sudoku is a shortening of a Japanese phrase meaning that each number must appear only once. Because the name is a trademark in Japan, many puzzle books there use other names for the same puzzle.
Saying them the Japanese way
English puts heavy stress on one syllable and reduces the others. Japanese gives each syllable roughly the same length and keeps vowels clear. That is why karaoke sounds like carry-okey in English and ka-ra-o-ke in Japanese.
Say these slowly with even beats first, then at normal speed. The goal is that a Japanese listener hears the word, not an English word that resembles it.
| Japanese | Romaji | Meaning |
|---|---|---|
| カラオケ | karaoke | Four even beats: ka-ra-o-ke |
| 津波 | tsunami | Start with a clear tsu, not su |
| お酒 | osake | Sa-ke with two clear vowels, not saki |
| アニメ | anime | A-ni-me, with the final e fully pronounced |
| 改善 | kaizen | Kai-zen, with no stress on either part |
Using them in conversation
These words make an easy topic with Japanese speakers, who are often curious about which of their words English uses and how English speakers say them. The conversation also works in reverse: Japanese has borrowed thousands of English words, and the katakana loanword guide covers that direction.
| Japanese | Romaji | Meaning |
|---|---|---|
| 英語でも「津波」って言うんですよ。 | Eigo demo tsunami tte iu n desu yo. | We say tsunami in English too. |
| 「カラオケ」は日本語から来た言葉ですよね。 | Karaoke wa nihongo kara kita kotoba desu yo ne. | Karaoke is a word that came from Japanese, isn't it? |
| 英語の発音だと、通じないかもしれません。 | Eigo no hatsuon da to, tsūjinai kamo shiremasen. | With English pronunciation, people might not understand it. |
