Hakone one day Pass

Could anyone please advise me if Hakone one day Pass is available,and how much. Also can I use JR East pass from Tokyo to ODAWARA station ,and purchase the 1 day pass there if available.

There is no one day pass! Only two and three day passes.

Also can I use JR East pass from Tokyo to ODAWARA station

Only on local and rapid trains along the JR Tokaido Main Line. The JR East Pass is not valid on the JR Tokaido Shinkansen.

Unfortunately, only a 2-day or 3-day pass is available. Here is the website:

It's still worth the price for one-day.

Thank you geogeek and Uji san for the replies.

One more question:

"Only on local and rapid trains along the JR Tokaido Main Line. The JR East Pass is not valid on the JR Tokaido Shinkansen."

Does Super View Odoriko stop at Oimachi station ? Or should I catch the train from Shinagawa station for Odawara?

Does Super View Odoriko stop at Oimachi station?

No.

Or should I catch the train from Shinagawa station for Odawara?

Yes.

As you pointed out, the pass is also valid on limited express trains along the JR Tokaido Main Line.
