Junko Kume and Isaac Ait Moreno moved to Tokyo last September for work, but they say it does not matter where they live as long as they can be together.
The 34-year-old Japanese senior assistant professor and her 32-year-old husband from Spain, who married in 2006, lived mostly in Madrid but also spent several months in both New York and Paris.
The international couple, who have both studied art history, hope to spread Spanish culture and language to Japanese.
