I see. I was specifically told by UFJ staff that a printout of a seal will not work for some of my bank papers. Hence was curious.
Aside, if you are coming to Osaka sometime and have a free evening, do let me know. Would love to hang out. Besides, I have to thank you in person for some excellent advice that worked out very well.
The key part of Patrick's comment is "routine business correspondence." Banking (or anything involving city/prefecture laws) are definitely not routine business, and would require the use of an actual seal (銀行印） that is registered with the city office.
When I was applying for my house loan, the exactitude of the forms I had to fill out was staggering, and each needed to be hand-written, in a specific format, with my personal seal that is registered with the city office. Any mistakes means I had to rewrite the form.
My invoices to clients, on the other hand, are generally printed and sent with the seal on them already. However, all of my clients do require printed invoices to be mailed to them.
