Renewing Japanese passport after acquiring a Canadian passport

Hello,

I understand this is not recognized/allowed in Japan and it's in the grey zone, but does anyone know or know of someone who has successfully renewed their Japanese passport after acquiring a foreign passport/nationality as an adult? My Japanese passport is expiring next year and ideally would like to keep my Japanese passport along with my Canadian passport. I'm willing to fly to Japan to renew it, but I wanted to know if people have been able to renew it recently without an issue.

TIA!
