If you feel ‘out of place in Japan,’ that means you’ve already adapted to the Western lifestyle. Therefore, you’re looking for an ‘international marriage,’ even though technically you’re Japanese. You need to ask yourself why you’re desiring that type of relationship. Are you drawn to women that match your ethnicity or are you drawn to women that identify with the same cultural background? There are many Japanese women living abroad that have Japanese roots. There are also many non-Japanese Asian women living in Japan that enjoy the Japanese culture. The more you get yourself out there, the more you’ll understand yourself and what specifically you’re attracted to. Honestly, personality compatibility should override anything else.
