That’s kind of like telling a poor person they could always go back to school and study to become a doctor, i.e., technically possible but extremely difficult. My understanding is that it is next to impossible to immigrate to Japan unless you have a Japanese parent or are rich and/or a celeb, but would love to be proven wrong! I would love to live there!
Thanks for the thoughtful response! I will keep this in mind (I do have a bachelor’s and am a former SE, currently sysadmin).
