国際結婚 ('international marriage') is a Sino-Japanese compound combining 国際 ('international') + 結婚 ('marriage'). The term refers specifically to marriage between a Japanese national and a foreign national — a category with its own legal procedures, paperwork (joint household registers under the koseki system are not granted to foreign spouses), and social status in Japan. 国際結婚 has gradually risen in frequency, though still represents only a small percentage of all marriages.
