Some Japanese words you don't need to say — you just need to recognize them. The moment you walk into a shop you'll hear irasshaimase (いらっしゃいませ), welcome; a train will announce tsugi wa (次は), the next stop; and a friendly daijoubu desu (大丈夫です) means "it's fine." Here are fifteen you'll hear all over Japan, and what to do when you do.
Knowing them turns background noise into signals. Most call for nothing more than a nod, but a few have a neat reply that makes you sound right at home. We've grouped them by where you'll run into them — at the counter, on the move, and among people — so they're easy to place in the moment.
In shops and restaurants
Staff greet every customer with a sung-out irasshaimase — welcome. You never answer it; a small nod is plenty. As you leave, you'll hear arigato gozaimashita called after you.
いらっしゃいませ
irasshaimase
Welcome (shop greeting, no reply needed)
かしこまりました
kashikomarimashita
Certainly / understood (polite, from staff)
少々お待ちください
shosho omachi kudasai
One moment, please
ありがとうございました
arigato gozaimashita
Thank you (called as you leave)
ごちそうさまでした
gochisosama deshita
Thanks for the meal (departing diners)
Kashikomarimashita is the ultra-polite "certainly" a server gives when they take your order, and shosho omachi kudasai simply means your food, or your turn, is on the way. Neither needs a reply — it's just staff being courteous.
On trains and streets
Station announcements are their own little vocabulary. Mamonaku means a train is arriving shortly, and tsugi wa introduces the next stop. If someone offers you a seat or waves you ahead with dozo, answer with a light domo — thanks.
まもなく
mamonaku
Arriving shortly (train announcement)
次は
tsugi wa
The next stop is...
どうぞ
dozo
Go ahead / here you are
すみません
sumimasen
Excuse me (squeezing past)
大丈夫です
daijoubu desu
It's fine / no thanks
On a packed train, a soft sumimasen is how everyone edges toward the doors, and shifting aside when you hear it is all that's asked. Catch mamonaku and tsugi wa together and you'll rarely miss your stop, even when the station signs rush past.
From the people around you
A few phrases stitch daily life together. Yoroshiku onegaishimasu seals introductions — an untranslatable "please treat me well" — and you simply say it back. Otsukaresama desu is the all-purpose hello-and-goodbye you'll hear in any workplace.
よろしくお願いします
yoroshiku onegaishimasu
Please treat me well (introductions)
お疲れ様です
otsukaresama desu
Thanks for your work (workplace hello/bye)
はい
hai
Yes / here you go
気をつけて
ki o tsukete
Take care (a warm send-off)
すごい
sugoi
Amazing / wow
Daijoubu desu works in both directions: someone may ask it to check you're okay, and you can offer it as a gentle "no thank you" when a shop pushes a bag or receipt on you. Otsukaresama desu has no tidy English match — it acknowledges someone's effort, and coworkers trade it like a hello all day long.
You'll also overhear sugoi (すごい), amazing, and kawaii (かわいい), cute, constantly — they pepper ordinary conversation. Both are safe to use yourself the moment something delights you.
