one good thing is to apply into a japanese firm in your country. trust me studying the japanese culture and actually living in it is very different. Some Japanese firm sends there employee in Japan for training which are called Kenshusei.
Take me for example, I worked in a Japanese firm for 4.5years in my country. During my stay there, I studied Nihongo and learned the working ethics of the Japanese. Also in that span of time I was sent on a Business trip to Japan twice and for AOTS training. Then I got a chance, when I applied in a Japanese firm base in Japan 2 years ago, got accepted and been working here for 2 years.
