Hi, I will be traveling to Japan in March next year. Thus, here is the big picture of my itinerary.
This trip, I am more focus balance of city and scenery environment. Mix of both worlds. Any recommendations?

Also when comes to JR Line Pass - I saw it cost RM1k plus and must be purchased in Malaysia right?

-Roam freely around Shibuya surroundings for supper.

Day 2

Day 8 - Flight is night flight (11pm)
