My "main reason" would entirely depend on my audience. If I were talking to a Japanese friend I'd point out that you can earn much higher interest rates by buying HBD than you can earn from a typical yen savings account (0.2-0.4%). Actually, I have had this conversation with one particular Japanese friend for several years now and he is fascinated by MY progress, but not so keen on taking action himself. 😂
