Across the world, オカダ (オカダ 
, Okada 
, Kazuchika

The first name オカダ is characteristic of Japan, where it is a rare masculine name, China, where it is a very rare primarily masculine, but very seldom girly name, and Indonesia, where it is a very rare male name. Much less frequently, オカダ is the last name as well as the forename.
