  • 2     ni
  • 3     san
  • 4     yon / shi
  • 5     go
  • 6     roku
  • 7     nana / shitchi
  • 8     hatchi

  • 16   jū -roku
  • 17   jū -nana

  • 19   jū -kyū
  • 20   ni-jū

 Japanese uses two names for numbers, Japanese ones and those based on Chinese pronounciation, which are the most common, but the Japanese ones are often used for cultural and ease of pronounciation for numbers 4 and 7, which is why you can hear both.

Pronunciation and transcription

Note on the pronunciation of Japanese

[Long and short vowels]

There are 4 main vowels in Japanese, [a / i / u /e /0]

Overlined vowels (written with a macron sign):
Ā/ā – Ī/ ī – Ū/ū – Ē/ē – Ō/ō
indicate that these are longer, extended vowels

[A] vowel

The [a] sound is pronounced somewhat like the English [a] in apple or party

[E] vowel

The vowel written as [e] is never pronounced like the English [ee] sound, but is actually close to /ɛ/ or the French [é] sound, or the final vowel of the Italian word latte for instance.
Karate for instance, is pronounced [karaté], never [karatee].
See this page for some examples

[I] vowel

The short [i] is pronounced like the i sound in the words hit, interesting, inner or pity
The long [ī] is pronounced like the English [ee] sound, as in the word tree

[U] vowel

This is a difficult sound, with no real English equivalent.
The short [u] is slightly similar to the u sound found in the words book or look
The long [Ū] is somewhat like the u sound at the end of the word new
The final short [u] is often hardly pronounced, and can be considered a silent vowel desu / masu = [dess] / [mass]

[R] consonant

The [R] sound in Japanese is very soft, and quite close to the [L] sound in English.
It actually sits somewhere in between [R] and [L]. Never roll your tongue or trill it.
Actually pronouncing the [R] as [L] will not be perfect, but closer to the Japanese sound than and English [R] sound

[Double consonants]

Double consonants are always pronounced, school, gakkō is pronounced GAK-KŌ

More on Japanese pronunciation here and here

Transcription convention used

When transcribing Japanese words of names, the overlined vowels (with a macron sign):
Ā/ā – Ī/ ī – Ū/ūĒ/ē and Ō/ō
indicate that these are longer, extended vowels as opposed the shorter ones.

This convention is not standardised in Japan and elsewhere, where you’ll encounter a great variety of transcriptions used, but this one is quite clear.

Please note that we always try to use a phonetically correct transcription, including for well-known place names that are often written untranscribed.

Indeed, pronouncing words or names correctly definitely helps with communication, some names being difficult to recognise when long vowels are not pronounced, especially to a Japanese ear.
Common names such as Oshima and Ōshima, are completely different for instance.

As an example, the country’s capital, usually written Tokyo, is actually pronounced with two long [ō] sounds and should be transliterated Tōkyō, whereas the name of the former Imperial capital, usually written Kyoto, is pronounced with a long [ō] followed by a short [o] sound, and should be transliterated Kyōto.

Cultural note

Japanese names and use of -san/-sama

Japanese names, as in other neighbouring languages (Korean and Mandarin Chinese for instance) are presented with the family name before the personal/given name
As an example, in Japanese, the famous film director’s name is always KUROSAWA (family name) Akira (personal name).

For readability however, and since we are writing in English, when naming people in these pages, we use the non-Japanese convention, which is more common in the English language, i.e. the personal/given name followed by the family name, e.g. Akira KUROSAWA.

In a traditional Japanese setting, people are also primarily referred to by their family names, which comes first.
In Japanese, someone called Akira (personal name) KUROSAWA (family name) will introduce himself as KUROSAWA, or KUROSAWA Akira, and will normally always be referred to by others as Kurosawa-san, san being a unisex suffix covering Mrs/Ms/Mr.
It will almost always be Kurosawa-san, outside a very close circle of friends, family etc, and also for hierarchical/ in-group/out-group reasons that we won’t go into here.

As an important note, -san is never used for one’s self, meaning no one would ever refer to themselves using the suffix –san.

In a formal setting, such as a customer service situation, -san will be replaced by the honorific –sama, which you might sometimes hear used in combination with your name in Japan (Kurosawa-sama, Johnson-sama) – this is just a more polite way of addressing someone.

So how should you address people in Japan?

Well, the most logical thing to do would be to address people à la japonaise, using the family name + -san.

This has become quite common in English as well, since –san can be formal, but also, depending on context, much less formal than Mrs, Ms or Mr…

However, since you are most likely non-Japanese, and more importantly most likely a non-Japanese speaker, this is not really expected of you.

And since Japanese people are well aware than most in most of the languages visitors speak, the personal name comes first, and most people will introduce themselves with the non-Japanese name order in English, “I am Akira KUROSAWA”, or simply with the their personal name “I’m Akira”.

Or even, because diving activities mostly take place in an rather informal, leisurely setting, people might even introduce themselves with their common nickname, and/or tell you what they want you to call them.

Mr Akira Kurosawa might like to be called “Aki”, “Kuro” or even something else like “Kuma” in the diving environment for instance…

If in doubt, go for the standard family name + san, or personal name+san, you can’t go wrong with that.

Or simply just ask the person what they would like to be called_and add –san (Akira-san, Kurosawa-san, Aki-san, Kuro-san, Kuma-san) for good measure/standard politeness.

All this to say there is no set rule, both because you, as a non-Japanese-speaking foreigner, are naturally outside the traditional setting Japanese cultural interactions, and seen as coming from a culture / using a language where one’s “personal name” is more important, and also because diving activities usually take place in a slightly less formal, more relaxed context than others.

Also keep in mind that some people might actually be looking forward to using personal names with you, as a refreshing change from the set everyday interactions of the standard Japanese cultural setting they usually evolve in.

You might even hear more informal suffixes such as “– chan” or “-kun” being thrown around, but these are tricky as they are less neutral, so we recommend that you stay on the safe-side and stick to the neutral –san­, unless direcly instructed to do otherwise.

That said, as a non-Japanese speaker, outside a formal setting, it would be hard to offend someone by using an “improper” address form, and you might actually get a few laughs!

In one Japanese dive-centre we worked for outside Japan, which catered to both Japanese and non-Japanese guests, everyone used personal names, including the Japanese staff for themselves, which is slightly exotic, but makes perfect sense in a mixed-language setting.

Japanese guests would use their guide’s personal names, but not the reverse – guides would address Japanese guests in the standard Japanese fashion, using their family names…

You’ll most likely be called by your first name, say simply Robert, or a semi-automatic Robert-san.
Just remember not to use the suffix –san for yourself, as this is just plain weird!
