Sorry for the long reply.

That is funny haha. About Japan, it's a great country and I think you will enjoy it if you stayed for 1-2 years. But long term it might be difficult, depending on your goals and your attitude. In my case, my original goal was "I want to test living in Japan to see if I want to live here forever" and to do research. I like the research but staying forever? I'm not sure. I asked my friend, he's Japanese and speaks British English as a hobby, why don't you want to live in the UK? He said, "Because living in Japan is more comfortable and I'm Japanese". That's when I realized that many people just live where they live because it's comfortable (same language, similar culture, and family is nearby). So I thought, why am I trying so hard when I can live in a place that is easier for me? I was cheering for my local football team here, and Japanese are very very prideful of their hometowns. And tbh, I've picked this up trait too from my Japanese friends, and I found myself become increasingly conservative over time too lol.

There are concerns you have to think about if you want to stay forever as well. It's very hard to be an expat in a country that doesn't speak your language/culture, and it wore me down feeling a great distance between the culture inside me and society. Although I can still be part of society I would just have to find my role. Despite adapting to the culture quickly and improving my Japanese a bit, a part of me wanted to become "Japanese", by changing my inner culture or something, but I found that no matter how hard I tried, it is not possible. I was young and foolish, please excuse me haha. It became easier for me once I accepted that I am half Canadian half English and I cannot change it. Sadly I learned that race and culture do impact our lives and it's something out of our control. Your chances to assimilate into a different culture from what I've seen, is much easier if you are from a similar culture too (for example, Korean/Chinese assimilate faster in Japan or Canadians into British culture). I also want to have kids in the future so this concerns them too. Maybe by the time of my grandchildren would they be considered Japanese. If I had kids, for example with my gf (although I plan to break up with her soon since I don't think we are compatible as she wants to stay in Japan and I want to leave, and I don't want to waste her time), our kids would not be considered fully Japanese, it depends greatly on their situation how well they will do which will cause some hardships for them.

Lastly, Japanese society/culture if I had to simplify it, imagine a rice farming village where everyone has to work together and get along to survive. Now expand this village to the entire country, so Japan is actually the borders of the Japanese tribe. This I realized is the same for most countries in the world, that they are the borders of tribes. Except maybe countries like Canada where there is a "path" to be somewhat accepted as Canadian (but even now I question this). So now that I'm job hunting and planning to move to a different country, I'm considering which countries I have the best chance to adjust to their society, get a job, and have the shortest cultural distance to mine (cold&dark countries, language similar to English, have beer and cheese, similar communication styles/socializing etc). I am also from a small town, and I also want to move back to the countryside too haha

To live in Japan long-term, you will need a strong motivation to keep you here and essentially I lack motivation. But you're only going for 1-2 years, so you don't have to worry about any of this. Japan is still a great country, people are alright, have fun, make connections, and enjoy your time while you're there :)
