Damaged JR passes

Unfortunately our JR passes have been through the washing machine. we are in japan. i have dried them and taped them but don’t think they will go through a ticket machine. can i get them replaced? i still have the original paperwork. we have 2 weeks left of out holiday- Takayama- Kanazawa then 8 days in kyoto with day trips and then back to narita airport. Can i buy a regional pass in japan? Any other suggestions.
