I applied through a recruiter. I interviewed at Nissin Travel Service
Interview
If you are not in the area to start with, first a skype interview, then an in-person interview. There is a short quiz in Japanese if you aren't a native speaker. (Good idea to brush up on travel-related vocabulary.) You may have to type in Japanese on the skype interview.
Interview questions [1]
Question 1
They may propose a potential problem scenario (such as the transportation provider booked didn't show up for the client) and how you would take care of it. They said there isn't necessarily one right answer.
