Yes,you can.If you can prove it by presenting a certificate issued by an embassy/consulate general of Japan.
Please note that the certificate is not qualified if you have not lived in the same province for more than 10 years.
For exmple:
Qualify: If you have lived in Vancouver, BC for 7 years and Kamloops, BC for 3 years (Total 10 years).
NOT Qualify: If you have lived in Vancouver, BC for 7 years and Toronto, ON for 3 years (Total 10 years).
