I've been staying in Japan for 8 years under a visa called "Intra-company transferee (企業内転勤)"and have been thinking of naturalization. I heard that one of the requirements is declaration for world wide income. Given the nature of my visa, I receive salaries both in Japan and in the Philippines. (taxed in each country). However, it's the first time I heard about world wide income tax, etc. I was worried it would affect my application. Can anyone help explain how it works and say I transfer taxed money from the Philippines to Japan (not through remittance services) but instead through bank transfer from the company I work for, do I need to declare these and is it taxable in Japan?
