I have a second home in Japan. Foreigners can buy apartments, houses, and land in Japan. As a non-resident I can't open a bank account in Japan. So to pay the property tax, I have a local agent and I wire over the money to him, and he pays the tax (and other stuff like water, electricity, broadband, gardening, landscaping, whatever). I am NOT the first person doing this! Believe me, real estate companies in Japan provide this service to foreigners. There are hundreds of foreigners who own property, mostly apartments in Tokyo, and they come to visit on a tourist visa and stay in their Tokyo apartments which are stocked with their clothes, art work, silverware, personal effects. Of course, they never overstay their tourist visas and they have other homes outside Japan where they spend most of the time. Right now, a lot of Chinese are buying up Tokyo apartments and they take suitcases of cash to pay for them. Japan taxes people based on residency, unlike America which taxes people based on residency or citizenship. The criteria for being deemed a resident in Japan are the usual: spending more than 180 days in the country or having the primary locus of one's life in the country (this usually means your business, family, job, are in Japan). None of these apply to me. I don't work in Japan, have no desire to work there, have no family in Japan, can't even speak Japanese (although I'll probably take language lessons).
I will contact the various moving companies that the people on this forum have recommended and pose these questions. I could also just send my boxes to the agent (probably the simplest way to get this done).
