First thing first. Bow when saying hello and introducing yourself. The severity of the bow depends on the other person's age, position in society, among other things. Another tip is do not interrupt the other person while they are talking. It's very rude.
Okay. Here is the romanji of hello, what is your name.
Konnichiwa. *bow* Watashi no namae wa "your name" desu. Hajimemashite. *bow* Onamae wa nandesu ka?
That translates into this: Good afternoon. My name is "your name". It's a pleasure to meet you. What is your name?
"onamae wa nan desu ka"
name what is ? <-- what it reads in english directly.
but in japanese is 'what is your name?'
or less polite:
namae wa nan desu ka
if you want someone elses name like their brother's or friend's you could say:
brother == onisan no onamae wa nan desu ka.
friend: tomodachi no onamae wa nan desu ka.
no= shows posession -in this case-
wa= marks the topic
ka= question mark -- makes it a question.
Answer
Well, I'd be careful in that it may be a bit rude to say "onamae wa nan desu ka?" Especially after introducing yourself, it's more natural to simply say "onamae wa" (with a rising tone, for both guy and girl speakers) and the rest of the sentence is assumed.
Answer
Pronunciation hasn't really been addressed here which I think is important. People won't understand you if you just say it like it's written in English.
"Konnichiwa."- Pronounced 'Kon-nichi-wa' (Not kon-nichi-ha, even though it is written with the hiragana "ha." This "ha" is the topic marker post-position "ha" and is pronounced as it is in its particle form - wa.)
"Watashi no namae wa 'your name' desu." - Pronounced 'Wa-ta-shi no na-ma-eh wa 'your name' dess.' (Please don't say 'Dehsoo' on westerners it's just wrong even though some Japanese people do pronounce the 'u'.)
"Hajimemashite."- Pronounced 'Ha-ji-meh-mahsh-teh'
"Onamae wa nan desu ka?"- Pronounced 'Oh-na-mah-eh wa nan desska.'
Aside from pronunciation I would also answer that this is in the wrong order. It's more Japanese to say 'Hajimemashite' first and it's quite western to say it last. I would personally suggest this as an introduction:
"Hajimemashite, watashi no namae wa 'your name' desu. Douzo yoroshiku onegaishimasu. Onamae wa?"
Pronunciation- "Ha-ji-meh-mahsh-teh, wa-ta-shi no nah-mah-eh wa 'your name' dess. Doh-zo yo-ro-shi-ku o-neh-gai-shi-mass. O-nah-mah-eh wa?"
If you could pull that off most Japanese people would be seriously impressed. Basically it means, "Nice to meet you, my name is 'whatever'. I hope that we'll get on. What's your name?" It sounds odd in English but Japanese manners and sentence structures are very different to in English.
If you're being really polite rather than saying "Watashi no namae wa 'your name' desu." you could say "''Your name' to moushimasu." ("'your name' toh moh-shi-mass."- I'm called 'your name'.) but this is a higher level of Japanese.
Answer
If you're doing a formal introduction, specifically asking for someone to give you their name is redundant - If you're introducing yourself, it is assumed they will be introducing themselves, thus there is no need to ask directly. "Onamae wa nan desu ka" should not be used in those situations unless someone has neglected to introduce themselves.
It depends on his name, and his rank in society. The best way is; Konichiwa NAME-san. -San means Mr/Mrs/Miss/Ms, and is respectful. You could also say; Ohayo gozimasu NAME-san Which translates into 'Good morning Mr. NAME' Oops, I completely forgot about something. If you were to talk to your teacher, it would most definitely not be -san. It would be -sensei.Ohayo gozimasu NAME-sensei. Which translates into 'Good morning Mr. NAME' (Teachers only)
you could say
hello how do you do?
konichiwa, hajimemeshite?
The better way of saying "hi how are you?" in Japanese is
O Genki Deska
The reply can be
Okage samade desu - This means "I am fine."
"Sumimasen kedo, o-namae WA nan deshoo-ka." Or better, "Sumimasen ga, nan to osshaimasuka?"
You could say, "Nani mono da?" and you would then be something like a cop confronting a second-story break-in burglar.
誰でしょうか? daredeshouka? Is very direct and can be either rude or friendly depending on the situation.
。。。です、そちらは?...desu, sochira ha? Saying your own name, then indication you'd like to hear the name of the person you're talking to.
There are several ways to say hello, which depends on what time of day it is, or where you're saying it.
Ways of saying hello:
こん (kon) This can be used on the computer, but keep it for the computer only. If you say it when you're not on the computer, it's kind of like saying 'lol' when you're talking in real life. Doesn't sound right. xD
もしもし (moshimoshi) This is used when you're talking on the phone. Yet again, keep it strictly for phone talk.
おはよう (ohayou, the u is silent) This is more of a "good morning" kind of a thing, but you use it like when you come to school/work, or go to a store or restaurant in the morning.
こんにちは (konnichiwa) Use this more around noon. When it's not quite morning, not quite evening.
こんばんは (konbanwa) Think of this more like "good evening" but it's commonly used, unlike good evening is in America.
To say "how are you" there are two ways, depending on who you're talking to.
お元気ですか (ogenki desuka) This should always be used when meeting someone new, talking to an elder, or talking to someone of respect, like a teacher.
元気ですか (genki desuka) This can be used when talking to peers or people you know well.
Remember- when asking "how are you" there is no question mark, because the ka at the end shows that it's a question.
So, to say "hello, how are you" just say the appropriate way to say hello, and then the appropriate way to say how are you for the situation.
