Can 42 year old unemployed still move to Japan for work?

I don't think 42 years old is the 'older age' for immigrants. My father is over 60 years old and has immigrated to multiple countries. My father-in-law's first time going abroad for business was also after the age of 55. So age is not a barrier to immigration.

Being unemployed or already unemployed does not directly affect immigration, unless your unemployment involves violating immigration laws or regulations. In summary, your question has little to do with the possibility of immigration.

I currently have resident status in 5 countries, and I hope my experience can be helpful to you. Immigration is not an escape, but a transition from one environment to another, and this new environment can provide you with a better platform for development. But remember, immigrants cannot hope to hide in a new environment just because they encounter setbacks in the old one. No matter what your motivation for immigrating is, I hope you can maintain an optimistic and enterprising attitude, continue to learn, and face various challenges. In the pursuit of a better life, immigrants will inadvertently achieve it.

I often say that immigration is just a process and never the ultimate goal. Immigration is not a panacea for all problems, it is just a new platform to help you achieve higher and more far-reaching development. So, as long as you have the drive and motivation to find suitable partners and use scientific methods, I believe that no matter which country you immigrate to, you will succeed.

If you have any further questions, please feel free to leave a message. I have a business consulting company in Tokyo that may be able to help you solve your questions about immigration or doing business overseas. I hope my experience can be helpful to you. thank you.
