Most washers (especially top loading) in Japan don't support warming water so people wash with cold water, use hot bath water, or hopefully the house has hot water faucet for washer. I've bought an expensive front loading washer-dryer with water heater (upto 60C) and heat pump dryer recently. Now I always wash with at least 15C water, even 15C, it's significant difference in cold winter situation.
