Japan Honeymoon in Winter

Hey Everyone!

We've never been to Japan before and would love to spend our honeymoon there. Our wedding is late December, and we prefer to honeymood immediately after even though Springs in Japan seem to be the better time of year to visit.

Can anyone share their winter experiences?

Is an 8-day trip enough? How can we make it as Romantic as possible? How do we hit the major cities/spots in an order that makes sense, and best way to travel between each?

Thanks!
