Getting married at the Japanese City Hall

Today we went to the city hall, submitted our documents and filled up the konin todoke. However, I thought it's gunna be completed on the same day but the guy told me it will take a week to get it finalized and so then we can get our marriage certificate.

Has anyone had the same experience while trying to get married in a Japanese city hall?

The guy told me if there's any problem he will contact us, but if there's not then we can collect the marriage certificate at the city hall after a week.

Just a bit worried, coz according to what I've read online it often can be completed on the same day.
