Tokyo-Koyoto Return & Bus travel

Hi,

The JR Pass is made for long distance travel, and can only be used on JR trains (with a tiny number of exceptions). But JR does not serve the area close to Mt. Fuji. There are other rail passes you can buy from Odakyu for both the Hakone and Fuji 5 Lakes Area.
JR Buses on local lines can be used in some cities, but are of limited use and rail or other bus services generally more practical. You can use the JR Pass for example on the Yamanote Line, which stops at numerous popular tourist sights, such as the Shibuya Hachiko intersection, and Akihabara. In Kyoto you can use the JR Pass to take the Nara Line to see the Fushimi Inari Shrine and to go to Arashiyama. Going to Nara is also a great idea - there are numerous excellent sights, inlcuding the Todaiji Temple. There are many other side trips you could take to enhance the value of a pass, including going to Nikko from Tokyo and going to Himeji near Kyoto, which has the country's finest castle.

Best of luck.

Hi

Is there a Bullet Train ticket traveling from Tokyo-Osaka one way trip only? How much ?

Thank you

Yes, certainly. An unreserved seat is ¥13,620. But if you are not going to get the pass, you could also fly for much less on a low cost air carrier like Jet Star or Peach.

You can see regular rail fares and schedules on Hyperdia.

But since you are already seeing Tokyo, you can largely skip Osaka during the day. After the temples of Kyoto close down around 5PM, you can zip over to Osaka for the evening. At night the city comes alive and has some great places to see, such as Dotonbori, plus the night views from the Umeda Sky Bldg, and Abeno Harukas Bldg are excellent.
Nara is often neglected by some tourists, which is a shame. Missing the Todaiji Great Buddha would be a tragedy. Nara Park has a lot of other great places, such as Kasuga Shrine, Kofukuji Temple, and feeding the many deer in the area. A few other great places missed out even by those who go to Nara though are the Isuien
and Yoshikien Gardens. They are gorgeous and not crowded at all.
In addition, there are other numerous great places you can visit in the area. Okayama is not far and it is famous for its castle, plus Korakuen, one of Japan's Top 3, and also the Handayama Garden. If you'd like to get off the beaten trail for a while, the half day hike up to Konpirasan in Kotohira is stunning. Going to Takamatsu is also nice - it has one of Japan's finest gardens also, called Ritsurin.
Hiroshima also has a number of good places. Miyajima is the most famous, and aside from Hiroshima itself, Onomichi with its temple tour and Kosanji Temple is spectacular. Just beyond Miyajima also lies Iwakuni with its historical bridge and castle on top of the mountain.

All in all, a lot more to explore and enjoy.

Let's say I am staying in Granvia Hotel at Osaka, which rail line should I purchase? Which station do I choose to get down?

Thanks

Granvia Hotel is right by Osaka Station, so it is very conveniently located.
