less traffic in Tokyo

Self drive, Fujisawa - Narita. What is the best time of day and less traffic in Tokyo (between 10am and 8pm, Sunday). If it late evening, where could you recommend spend a day between those cities

I haven't driven this route enough to know time of day traffic but whenever getting from one side of Tokyo to the other, I've followed the Bayshore Route. Most of the time the traffic kept moving although once near Haneda, it was down to a crawl.

I wouldn't stop in between in Tokyo as it's tough to even find a place to park and if you got a late start, I would just stay around Fujisawa or Kamakura for an early start the next day.

If your question for the stop in between is for the day, i would drive from Fujisawa to Chiba Prefecture and then spend the day in the region close to Narita. Eg Sawara and Katori jinja, or down at the coast of Boso peninsula or even in Narita itself (there is a open air Museum closeby)

This way you can control when you�fll arrive in Narita for your flight departure.

Enjoy your trip to Japan!
