Daniel-San,
Based on your guidance to several other travelers- I believe the best option is the 7 day Rail Pass as ultimately we round trip back to Tokyo. But given this is my wife's Birthday trip I want to make sure...
Here is our proposed itinerary:
March 31: afternoon arrival at NRT- Hotel is near Ginza Station
March 31- April 3: Tokyo Proper day trips to Sensoji Temple, Imperial Palace, Tokyo Dome, Tsukiji Market, cherry blossom viewing, etc
- possible train to Mt. Fuji or we will see it on April 3 as we go by
April 3- Train from Tokyo to Osaka
April 3-5 Staying in Osaka - Hotel is near Shin Osaka Station
April 3 & 5 Day trips around Osaka: Himeji Castle, Osaka Castle, Nara, Miyajima/Hiroshima, Shinsekai
April 4 day trip to Kyoto - return to Osaka
April 5 - Train from Osaka to Tokyo - Hotel is near Ginza Station
April 6 - Evening flight from NRT- so probably will fit in a couple more sites or return to a local favorite
Appreciate your guidance and if the rail pass would assist on transit from NRT to Ginza district
thanks!
