This was incredibly well-written and an enjoyable story. Congratulations on pushing through and getting traction. Something that resonated: > We had to put 5 million JPY (~$45k at the time) in our business bank account and leave it there. For... some reason. Living in Asia I've come across this bizarre government obsession with "money in the bank" when dealing with them: "You need $15k in a bank account to apply" "Ok…
"Documents such as a bankbook to prove that the applicant’s savings is more than 30 million Japanese yen along with the records indicating the current balance as well as deposits and withdrawals for the past 6 months."

30 million yen is currently 225k USD, but rates can change rapidly so you need significantly more just to be safe as the visa application process is long. In my experience, the "such as a bankbook" is strictly interpreted as a bank account, a stock portfolio isn't acceptable.
Now the Visa is a 1 year visa, but it issued for six months and then renewed for six months. When renewing you must meet all the original requirements. So, you can withdraw the money after getting the visa, but you need to have it back in the account when renewing! The records for six months appear to indicate that you need the money in the account for six months, but I'm not certain if this is the case.
