Nagoya is facing stiff competition when it comes to wooing cruise liners.

Although the city boasts of being Japan's most profitable trading port, cruise ships made only 30 stops there in 2014, barely keeping it among the top 10 ports in the nation.

Nagoya is doing relatively well with Japanese cruise ships, coming in third after Yokohama and Kobe with 27 stops last year, but is having difficulty attracting foreign cruise ships as competition for tourism income climbs among other ports in western Japan.
