Need advice on Japanese driver’s license conversion

Hey Japanlife.

I have an appointment to convert my Canadian drivers license to japanese on the 7th. This appointment advises that i would need a japanese speaker to accompany me as my Japanese is still not super great. My wife just realized she has a conflict at work that requires her to be in Shiga on the 7th.

We are looking into finding someone who might be able to help at the Nakahara ward office but im afraid the timeline is too short. Does anyone have any suggestions on how I might hire an interpreter on short notice like this. I have been searching around but felt it wouldn't hurt to try posting here.

Thanks in advance first time posting here and still very new to Japan.
