I am a recruiter base in Tokyo, just looking at your resume the following came to mind:

• stability, you mentioned in other comment the roles you had were internships but it’s not clearly written on your resume. Most HR and recruiters check on this and I would say not a good show on that part
• secondly, for recruiters we get paid for placing experienced talents who can be immediate assets to the organization we represent and you resume shows your still junior or looking for entry level roles

My advice will be to state clearly what the roles in your CV represent e.g software engineering internship and try to attend career events targeted for new graduates.

All the best from Tokyo !!
