5) Voluntary withdrawal from the Japanese National Pension system

When you emigrate your home country which is an agreement country and immigrate to Japan, you may be granted voluntary withdrawal from the Japanese National Pension system. In order for you to withdraw from the system, you need to satisfy the following conditions:
You are subject to coverage under the Japanese National Pension system as a CategoryⅠinsured person.
The total of your coverage periods under the pension system of your home country and your potential coverage periods under the Japanese pension system (since the immigration month till you become 60 years old) is not long enough to qualify for Japanese old-age benefits.
On the other hand, if you have been already approved to voluntarily withdraw and you can become entitled to Japanese old-age benefits as a result of totalization of coverage periods of both countries, you can apply again to enroll in the Japanese National Pension system.

You may file a claim for the medical care expenses to your insurer.

7) Treatment when agreement enters into force

If your detachment or self-employed activity started prior to the effective date of each agreement, the effective date is considered to be the date when your detachment or self-employment begins. That is, you will be exempt from coverage of the Japanese social security system, if your detachment to Japan is expected to be not more than 5 years from the effective date of the agreement.
