I've visited Japan twice (although not for long enough to say definitively), but no, I didn't have the impression that it was something that people ate everyday although it was obviously not hard to find. 

Japanese cuisine is actually a lot more diverse than people realize, and this isn't something that I would say about every country that I've visited. 

I felt like I was always trying new food their. Okonomiyaki and Gyoza were two common dishes that I liked a lot. Gyoza is also generally pretty cheap and was probably my favorite dish when taking into account the price. 

I saw an article a while back (I can't find it right now) that compared the number of Americans learning Mandarin versus the number of Chinese people learning English. If I remember correctly the ratio was something like 3000 to 1. It might have been a little less and I think it only focused on American rather than native English speakers in general, but even if it's only 1000 to 1 that is still a massive imbalance. 

So yes, I would imagine that it's nearly impossible for Chinese students to find people to practice with. Keep in mind that someone who is learning Chinese has to be somewhat selective just in order to not be completely inundated with messages. 

With Spanish and French the ratio is a bit more normal, but the supply and demand still aren't equal. 

I'm not learning Chinese, but here's my advice for anyone from China that wants to practice with a native English speaker. Make yourself stand out in a good way. Don't say "can you teach me English", but rather "can I teach you Chinese". Write things in both languages and keep what you write relatively short so that the other person doesn't feel compelled to correct huge paragraphs. Correct mistakes, explain why one way to say something sounds more natural than another way... and last but not least, try to find someone that appears to have similar interests. 

You STILL may not find anyone, but this will at least increase your odds to find someone to help you with English. 

Hellotalk and gospeaky or both really good. In fact, I use them almost exclusively nowadays, but each site has their own strengths and weaknesses. 

For Spanish learners, Rype is pretty good. It's not free, but it can help you get up to speed quickly and to focus on things that you're struggling with. 

Thanks for the shout out Su.Ki. 

And yes Bill, it is a somewhat regional usage, but in fairness it's a region that's bigger than most countries in Europe both in terms of area and population. ;) 

In fairness, just like every rule there are exceptions. The one word like that that I do use a lot in text conversations is "gotcha". It just looks really weird to write out "I got you" and part of the reason you say it is to give a quick one word response (generally speaking). And in fairness, even native speakers do use them on occasion, but most (educated) people only use them sparingly in my opinion. A lot of English learners don't seem to realize that if you use those types of words a lot you'll sound like a teenage girl haha.  

"ur" and "imma" in particular drive me crazy. 

As far as audio clips of the pronunciation, attached is a link with some pronunciations.

And here're some clips for "y'all's" (which would be said even more often)

It's kind of funny though, because most of the people pronouncing those words have sort of a strong country accent. They're not helping my case haha. As a general rule though, I think that the faster that they're said, the less country they sound.
