When is the best calendar month to move

I’m in the process of getting my work visa and have a choice of picking my start date between nov 24 to Jan 25.

I will be provided 1 month of accommodation in a hotel before I have to find a place.

I wanted to get a view on what may be a good time to start considering it may be difficult to source for housing during the Christmas period; based on where I come from, but wanted to see whether this is the same in Japan.

Thanks
