Inheritance Tax and Land Sale Tax

Hello,

Last year my grandfather died and he left me land. I plan on handing this land over to my cousin for a sale of $1 soon.

As an American living and working in Japan for about 6 years, I assume the inheritance tax doesn’t apply to me due to both being a temporary resident (less than 10 years living here) and the amount the inheritance I received in the form of land is less than the basic exemption of 30 million yen. Am I right about this?

And since I’ll be selling my land for a dollar sometime soonish, I want to know how land sale tax will affect me here in Japan.

Thanks for any help!
