My first name is quite simple: "Yu". In English, you can pronounce it just like the second person pronoun "you" [ˈju] or [ˈjʉ] (but it shouldn't be reduced as in [jə]). --- So you don't really have to remember my name. You could just say "Hey, Yu/you!"
In Japanese, it is pronounced [jɯ̂ː], or more accurately something like [jíɯ̀] (pitch accent on the first mora, making it sound like HL). The Japanese "high back vowel" is usually realized as something like [ɯ], the close back unrounded vowel in IPA terms. (But it's quite centralized and produced with compressed lip rounding. So it actually sounds somewhat different from the canonical IPA [ɯ]). It becomes fronted when it is adjacent to a coronal or palatal sound. So the quality of the first half of the vowel in my name is usually close to [i].
My last name, Tanaka, is one of the most common Japanese surnames, which is pronounced something like [t̪àn̪ák̠á] in Japanese. (The two coronals are usually dental and the /k/ can be pretty back, sometimes even sounding like uvular [q], at least in my personal dialect. The word is unaccented, making the tonal pattern LHH, although H isn't that high.) It would be something like [tʰəˈnɑkə] in North American English.
To sum,
- In Japanese: [t̪àn̪ák̠á j
íɯ̀], [t̪àn̪ák̠á jɯ̂ː], etc. - In English: [ˈju tʰəˈnɑkə], [ˈjʉ tʰəˈnɑkə], etc.
and I am happy with any one of them.
