Question about Mercari verification?

So I am currently an ALT who’s looking to sell (and buy) some stuff on Mercari (mostly arcade cards and such) and I noticed that the balance I’ve accumulated has a time limit on it (180 days?). So to prevent that I’ve been trying to verify my account so I don’t lose my balance and I can use it to buy the next set when it drops. I’m struggling with the process though, particularly the question about “tax obligations overseas”. I still have to fill out my taxes in Canada while I’m here but when I say “yes” it tells me to list my overseas address which I don’t have (cause I live in Japan). So what should I be filling out here?
