Same

Same here

No, when you are referring to yourself -san is not used. It is just used to politely refer to other people but never to yourself. When you say your name and want to talk politely just add -desu, and if you want to be informal just drop -desu, although it can be considered very rude to avoid the use of -desu.

I was wondering the same

I think you might be misunderstanding a little (which is completely understandable since many comments try to simplify things as much as possible).

Functionally, 「田中です」and「田中といいます」are both statements that can be translated to "I am Tanaka." Implicit in both of these is the subject, usually assumed to be the speaker.

However, this is where grammatical differences come in. In the case of「田中です」, explicitly including a subject, e.g. かれ(he/him) or かのじょ(she/her), simply changes the translation to "he/she is Tanaka."

For「田中といいます」, it's not so simple. いいます can also be written as 言います, which means "to say". Basically, what is implicit in this case is something along the lines of "Tanaka is what I say about myself", which often becomes translated to "please call me Tanaka (because that is what I call myself)". It's considered more polite than です because it's very deferential, like you're saying "I call myself Tanaka, but you can call me as you like" whereas です is kind of saying "this is what I am (like it or not)." The tricky thing about といいます is that it's exactly the way you would quote what someone else says. Therefore, if you change the subject (in order to introduce someone else), the sentence changes to "he/she says "Tanaka" ", but no longer functions as an introduction, rather an introduction of the strange things he/she likes to say. That's why it is only ever used to introduce yourself.

To explicitly ask someone to call you by a certain name, you need to use a slightly more advanced grammar structure. For example, my name is Joshua, but I prefer people to call me Josh. So when I introduce myself, I would say「ジョシュアといいます。でも(But)ジョシュと呼んでください(yonde kudasai call please)」

Sorry for such a long comment, but it's hard to concisely explain all the nuance using just text.

田中です means "I am Tanaka" 田中といいです means "my name is Tanaka"

I'm Tanaka, or Call me Tanaka . Both of this structures do the job of introducing yourself.

Basically its the polite version of im tanaka

Whenever you want to add more context. For example, マリアです on its own could mean "I'm Maria" or "It's Maria" or "She's Maria". But adding 私は beforehand makes it absolutely certain you are referring to yourself. It is unnecessary in many cases.

A good way to remember WA usage is to imagine it means "As for... <the thing I just said before WA>"

と here is a particle, and it indicates the thing before it as "quoted information". So, in (私は)田中といいます, it means As for me, I am called "Tanaka".

Think of it like Mr/Mrs/Ms. If you were introducing someone, you might say, "This is Ms. Johnson." But you wouldn't say, "I'm Ms. Johnson." Here the context is a self introduction, so no ~san.

You do not add san if you are introducing yourself

Exactly, it's an honorific, as in it's supposed to convey honor to the person it refers to. Referring to yourself as -san, or any other honorific for that matter, is seen as incredibly conceited and it's never done (since Japanese culture emphasizes humility).

Yes, you could!

Personally, I would say 「田中さんですね？はじめまして」 if they just introduced themselves, which lets me confirm that I heard their name correctly, I am pronouncing it correctly, and they are ok with me using the さん suffix.

です is the polite form of だ. You should generally use です with strangers or people you aren't close to.

はじめまして = a set phrase/greeting used when meeting someone for the first time; no direct English translation, but usually translated as "nice to meet you"

田中 (たなか) = a common Japanese surname (family name); Japanese people are usually only called by their first/given names by family and close friends

です = the copula/verb "to be", usually being translated as "is/am"; it equates the object (in this case, "Tanaka") with the subject (in this case, the implied "I")

What anime you're watching bro ? :D

You mean 田中といいます, and this has already been answered on this discussion page. I explained it in quite a bit of detail in an earlier comment to @Digicrests 's question. Go have a read.

Well, it's not a simple case of having it or not. は serves a specific purpose in Japanese grammar and understanding that will help you understand when は is and isn't used.

To that end, I would suggest reading some of the other comments here, and on the other questions/discussion pages, but if you don't have the time or effort for that (or even for a quick Google), I'll give you the short answer:

は is used to indicate the topic of a sentence. In Japanese, when the topic (which is often also the subject) is obvious through context, you can omit it, which means you also don't need the は to indicate it.

No, if used in that manner, が actually becomes like "but"/"in spite of that".

"Nice to meet you, but I'm Tanaka" doesn't really make sense.

No, it shouldn't. You can't just stick your は anywhere you like and get away with it.

は serves a specific purpose in Japanese grammar, so it's only correct to put it in when it's needed for that purpose. (To be more accurate, there are a few different roles は can have, but the idea still holds; you put it in to fulfill one of those roles.)

In this sentence, if you wanted to add は, it would most likely fill the role of "topic particle". It's essentially a grammatical equals sign, when used inＡはＢです, that says "A is/can be described as B."

So, if you put は in front of 田中, you have {blank}は田中です and you're describing something as being "Tanaka" without saying what that something is. Alternatively, if you put it after 田中, you have 田中は{blank}です and you're describing Tanaka without describing them. It's like adding an equals sign to one side of a number; it doesn't really make sense because it isn't a complete formula. Likewise, adding は doesn't make sense because it isn't a complete sentence.

Almost all Japanese names are written with kanji. Generally only foreign names are written in katakana.

You've got this the wrong way around. Japanese people generally NEVER refer to themselves with an honorific, including when they introduce themselves.

Not if you can already read! Guess if it's the first time you see it, or rather reduce, by deciding it's not the ones you already know. If it's too easy it will take you longer to remember
