It was quite mild even in December, and yes that's probably coz it's quite south. If you go up north to Hokkaido, which I want to go, I hear it can get very cold.
Which cities are you going in February? And have you got you wallet ready for Mrs Nathen's spending spree. You gotta treat the lady in Japan!!
Spending spree? Oh Lordy! We're flying in to Osaka as the only purpose of the trip is to visit Shirakawa-go to see the beautiful village in the snow. There'll be plenty of spending beforehand on winter clothes and multiple warm coats for the wife so she doesn't appear in the same clothes twice in her selfies!
Being a city boy at heart, I'd have preferred a five-star in Tokyo but you can't win 'em
allany ;-)Hope you had a lovely weekend and best wishes to you and hubby :-)
