TL;DR: If I put "September 10" as my arrival date on my visa application form, will I have problems if I enter Japan on another day instead?
I have been hired by an employer in Tokyo, but they have not told me my exact placement yet, and I have not booked a flight.
I just handed in my COE and other visa application stuff to the consulate. The guy who took my application noticed that I had put "TBD" for some fields on the form, and I explained that I was waiting to hear the exact placement details. He said that was fine, except for the "Date of arrival in Japan" which needed a specific date. After I wrote down an estimated arrival date, he clarified that it couldn't be changed, which presumably meant I could only arrive on that exact day.
My employer seems to think the date can be estimated and isn't set in stone. I also do not remember any entry date on my last entry visa for Japan. But will I have problems if I try to enter on different date than the one I put on the form?
