Pros
Get to live in Japan Respectful Colleges Job offer likely with successful internship No drug test Paid(Most internships in Japan are unpaid or extremely low-paid compared) They will find you housing if you work/live in Toyohashi.
Cons
Will not be given any meaningful work or work at all. Most of the day in spent day dreaming. HR and payroll is not transparent at all and attempts to conceal information from you. Extremely boring and worthless internship unless, you want to experience living in Japan. Almost all other interns will be people that major in Asian Studies with no knowledge on Business or Economics/the automotive industry. No "native" English speakers, most employees 98% of employees are either German or Japanese. So, if your Japanese is not very good, it will be a difficult experience. Toyohashi is an extremely boring part of Japan and if given the option, goto Tokyo. Although, your salary will not go very far in Tokyo. It will be 100% better than frequenting the same 3 bars that close at 11pm every weekend.
