The Most Common Japanese Words You Need to Know From a Native Speaker!

Japan is such a unique country. We have our culture mixing Asian and American tastes. The Japanese language: Nihongo, hase 3 different script components: hiragana, katakana, and kanji, therefore it makes it hard to read. On the other hand, speaking is very simple and most foreigners can pronounce things very easily (then accents become the key to speaking Japanese well).

I don’t want to frighten you but… most Japanese do not speak English fluently, especially in a small city. If you are in Tokyo, you can at least try to speak easy English but most of the times they will answer you in Japanese even if they understand what you said. This time, I’m gonna teach you very, very useful Japanese words and phrases to enjoy your trip or life in Japan. By the way, if you are planning to come to Japan, check out the article!

In Japanese, most of the times there are different levels of politeness from casual to polite. Talking about polite Japanese expressions, there are again many classifications which are pretty annoying even for native Japanese speakers. In fact, if we don’t know how to use those polite expressions, we are treated as non-educated people.

In general, as I mentioned, there are too many different ways to say the same thing, depending on the relationship, therefore, I choose one casual and one polite way which are used the most in daily life. From now, if I note two words to say the same thing, the former is the casual way and the latter is the polite way in Japanese. Because speaking the polite way is often longer than the casual way and hard to remember, if you’re a foreigner, you can use the casual way. If you’re obviously a foreigner, we don’t care if you use the casual forms.
* If I think you need to learn only the polite form, then I’ll note it.


To begin, let’s learn about simple Japanese greeting words. If you come to Japan for traveling, you’d better know all these Japanese phrases.

Sumimasen (すみません)

I’d say… Japanese love to use “Sumimasen” in daily life. If you bump into someone while walking, are asking a favor, etc., you can say ‘Sumimasen’. Also, we use this word as “Thank you” too. For example, I drop something on the floor and someone picks it up for me, I’d say “Sumimasen.”

There are two main ways to say ‘beautiful’ in Japanese. ‘Utsukushii’ or ‘Utsukushiidesu’ is a more polite and elegant way to say it. On the other hand, ‘Kirei’ or ‘Kirreidesu’ is a more casual or familiar way. For example, among my friends, I use ‘Kirei’ most of the times.

Yes/no in Japanese

How to say “Yes/No” in Japanese?

Hai(はい) / Iie(いいえ)


Un(うん) / Uun(ううん)

Saying ‘Hai’ and ‘Iie’ won’t be too hard to pronounce. However, ‘Un’ and ‘Uun’ are tricky. They sound similar but ‘Uun’ should be longer than ‘Un’. For not to make Japanese misunderstand, it’s better to use body language while saying the word. If it’s yes, nod your hand and if it’s no, shake your head.

How to say “I’m from (country name) ” in Japanese?

Watashi wa … kara kimashita (私は…から来ました)

In my case, “I’m from Japan” = “Watashi wa Nihon kara kimasita”. 

For your country name, you can say it in English because most country names are pronounced similarly in Japanese so Japanese people can understand.

Yoroshiku onegaishimasu

how to bow in Japan

Yoroshiku (宜しく) / Yoroshiku onegaishimasu (宜しくお願いします)

There isn’t a straightforward way to translate “Yoroshiku onegaishimasu” from Japanese to English. It’s definition in Japanese changes dramatically case by case, as well. It’s often translated as “please take care of me”. It’s something you use after “Hajimemashite” when you meet someone, you can also use it when asking someone for a favor.


Travel in Japan

From here, I’d explain some Japanese words you will definitely hear while traveling or living in Japan.

Welcome in Japanese

Welcome in Japanese

How to say “Welcome” in Japanese?

Y­ōkoso (ようこそ) or Irasshaimase (いらっしゃいませ)

The words above are used in different situations: Y­ōkoso is for a country or event like “Welcome to Japan” or “Welcome to our party”, etc. Irasshaimase is what workers in a shop or restaurant will say as you enter.


Studying JLPT

A lot of people in Japan are pretty shy and don’t have the confidence to speak in English. Therefore, when a foreigner speaks a few Japanese words such as hello or thank you, it makes us ultra happy!

I’ve explained to you the easiest Japanese words but you may have to look for more words and phrases depending on the situation. I made a simple list here to make it easy so print it out and keep it with you while traveling or staying in Japan!
