Is reservation needed to enter Shirakawago?

In January, I'm planning to take a day trip (driving) to Shirakawago from Takayama.

Does one need to reserve a carpark to visit Shirakawago during the daytime?

It is because I read that one needs to reserve a carpark for the light-up event, so I wonder if is it the same for day-time visit?

Considering the event is quite famous and no doubt will attract many visitors, reservation at that time sounds necessary. I have been there when there were hardly any cars, so my observational response would be that on an ordinary day, there is no need to reserve a parking spot, especially during the day. Many visitors do come by bus, but they take up quite a bit of parking. I�fm sure they park further away from where personal vehicles park.

You do not need a reservation for a day time visit. Only for a visit on an evening when the light-up event is held, and I believe private cars cannot be driven into Shirakawago during those times anyway.
