Come back to my home country Australia, and it just doesn't feel the same here. They' re on another level over there, like a higher advanced civilization 

As a fellow Aussie who has visited Japan twice, yeah, it is very impressive there in terms of stuff like technology, order and tidiness, politeness, etc.

Every country has its good and bad points though; Japan for instance has an incredibly harsh work culture, to the point where they have a word for overworking yourself to the point of suicide.

It's an amazing country to visit, but for me the more laid back Australian lifestyle is preferable, I don't think I'd be able to handle living in Japan long term.

Really want to go some day. Looks amazing.

I am so fascinated by the japanese people and culture that I'm planning to move there. My japanese skills will have to improve a lot though. But I'm getting there. I would actually prefer some calm village somewhere in Hokkaido where it doesn't get so absurdly hot in the summer. But my son is afraid he won't make it in a japanese school, although he is generally excited about the idea of moving there. So we are right now targeting to move into the neighborhood of the only german school in the country - right in Yokohama, lol.

Anyway, Japan is indeed a great country and I can totally understand your feelings. At the same time, it also has its downsides and it's not some miracle wonderland. The economy is pretty rough these days and people have a hard time just paying for their daily needs. Imports are pretty much out of reach for most people because of the absurdly weak Yen. Oh, and japanese rice has also gotten really expensive. People are already switching to bread and noodles. In Japan of all places. Where the word for "food" and "rice" is literally the same! Stuff like that feeds populism, which is also why right-wingers and xenophobia is on the rise lately, although it isn't nearly as bad as in the US or Europe (yet).

Recently visited Japan for 2 weeks. There was a lot to like, but my experience with the country is not only positive.
I have never been in a place with so many people feeling so lonely. There are something like invisible walls between people everywhere, and in restaurants often physical ones. I live in Sweden, and we are one of the most closed in people around, but the general aura of Japan was something else. It is respectful and unintrusive to the point of being void of warmth.
I'm glad I visited, but I will not return. But it was nice always feeling completely safe.

Out of curiosity, do you know the language? Because I'm also from Sweden and I'm fluent in Japanese, and I feel a lot less lonely in Japan than I do here in Sweden. 

I second that, japanese people open up instantly if you speak even a little japanese. Which is only natural, because a lot of them can't talk english very well. Learning that for them is about as hard as learning japanese for english speakers.

I for one didn't have problems making friends in japan. Especially in the rural areas. In fact, people are a lot more welcoming there than here in germany, lol.

It's amazing how many people have the exact same experience post-Japan XD

No I do not speak Japanese in any meaningful sense. A few standard phrases. 

I visited Vietnam on the same trip before Japan. I do not know the language there either. Complete opposite experience and feeling from the people there. Usually I will not speak with anyone anywhere. Won't even speak to with new people at events where the whole point is to speak to new people. One could say that I'm not much of a talker. So the feeling is not from me trying and failing to have conversations. I never tried. It is from feeling like even trying would be disrespectful. Or even existing in some places. 

Yeah, I live here in Japan and never looked back. My 2 Japan trips before that, confirmed my feelings for the country. Trains are very nice for going on random trips. And it is a small enough country where you can go to places unlike my home country.
