Non-Japanese speaker: Seeking hospital in Yokohama for epidural (refused at current hospital)

I am currently 13 weeks pregnant and living in Yokohama with my husband. We are both non-Japanese speakers (we only know very limited/simple phrases).

I recently registered to give birth at Yokohama Municipal Citizen's Hospital (横浜市立市民病院). My plan has always been to have an epidural, but when I requested one, the doctor refused, citing that they do not provide epidurals to non-Japanese speakers.
I’m feeling very anxious and overwhelmed right now.

I have a few questions for the community:
1. Has anyone else had this experience at Yokohama Municipal Citizen's Hospital?
2. Has any non-Japanese speaker had an epidural at Keiyu Hospital? I am considering transferring there, but I want to make sure I won't run into the same issue before I make the switch.
3. Are there other hospitals in the Yokohama/Minato Mirai area that are known for being supportive of epidurals for expats/non-native speakers?

I’m still early in my second trimester, so I want to make a decision soon if I need to transfer. Any advice or shared experiences would be greatly appreciated!
