>>40770622 (OP)Hello, anon, I'm sorry to say but there is no guarantee that you'll reincarnate as a Japanese person in your next life if you simply travel there and die in Japan. In fact, it may even have a negative impact on your chances of reincarnating as a Japanese person to begin with. So please don't go over there with that misguided expectation, that's not going to happen because that's not how reincarnation works.
Instead, what I can tell you for sure, is that how you live in your current life will have a big influence on how you'll reincarnate in the next life. So if you want to increase the odds of reincarnating as a Japanese person in the next life, then all you have to do is to live your current life to the fullest and to follow your passions, interests, and dreams to the best of your ability, and if Japanese culture happens to be one of them, then that very will may have an impact on how you'll reincarnate in your next life.
So please don't throw your precious life away, anon, your soul and your consciousness are extremely unique and important things that belongs to you and you alone, and I don't want you to regret your decision of committing suicide by having a negative impact on how you'll reincarnate in the next life. Nobody deserves to be born with their precious life only for them to throw it away because of depression and despair. I don't wish for that to happen to me or anybody else, and I hope it doesn't happen to you as well, my friend. So please live your life to the fullest, try your best to immerse yourself in Japanese culture and maybe even try learning Japanese and moving to Japan as a resident over there for as long as you can in your current life. This will certainly have a dramatic impact on whether you'll reincarnate as a Japanese person in your next life, so keep living on, anon. Make sure to get lots of Sunlight everyday without sun burning, it helps with depression and other mental health factors by a lot. Thanks, and good luck.
