Prepare answers both in Japanese and English. Before the interview make a summary of your work experience, and make sure you relate your experience to the position you are applying for. You can also mention your future career plans to show positive attitudes towards the work.
You should also be able to answer questions like "What do you know about our company"? and "Why do you want to work here?". Gathering basic background information on employers is crucial to successful interview. The company's website is a good source for learning about an employer. Be prepared to explain how corporate philosophy and culture resonate your value as well as how you can utilize your skills and experience in the position.
Avoid negative comments about why you are left your last job. Instead, you should mention something positive; for example, you are looking for a new challenge so you can grow your career.
When answering questions about your strengths, always keep the job description in mind and focus on strengths you have that are required for the job. The interviewer may lose interest in you if you mention strengths that are irrelevant to the positon.
When addressing questions about your weakness, no matter what weakness you select, try to put a positive spin on your answer.
Also, be prepared to answer to a question such as “how you have managed a work-related trouble in the past”. At the end of the interview, the interviewer often asks, "Do you have any questions?". Sometimes not having any questions is considered you have low interest in the position or company. It is better to prepare some questions in advance to show your enthusiasm and interest.
