how to get ssi in japan

I plan on going to okinowa for school and i get ssi here in the states how would i get it there and what are the benifits

What does ssi stand for?

social security insurance for disabled pepole

If you are disabled, why do you also want to work on a ship? It would be difficult for you to get insurance in Japan without Japanese nationality or having paid into the system for a number of years.

If you need support and cannot finance your stay you may not actually be eligible for a student visa.

yes i get ssi but that just pays for my medical that doesnt mean i cant go to school or work

People who receive Supplemental Security Income (SSI)usually do not qualify for regular Social Security. It is a 'compassionate benefit' with specific criteria. Not everyone is eligible. Other countries are not obligated provide this benefit.

Going to school in a foreign country is not an entitlement. So be prepared to support yourself--your own savings, scholarships, etc. Not to dash your dreams--it's possible--you just need to make a more realistic plan. It's not any government's responsibility to give it to you.

As shown in the links above, foreigners are entitled to join the regular health insurance system in Japan which you pay for as a portion of your salary- it's very cheap the first year but goes up substantially the second year. They cover 70% of most treatments at a hospital or clinic, and dental.

I'm not sure what happens with full-time students though, and as a foreign student you will be paying all your own fees and for your rent, food etc- the Japanese government will not support you financially in any way to study here unless you get the Mombusho scholarship (offered to only a small number every year, based on academic achievement in previous studies I believe).
