fuji shibazakura go runs On may

Hi Expert Team,

Im Agung from indonesia,my Family (wife & 1 year old daughter) and I, are planning to shibazakura on 8 May 2017.

I check at http://www.shibazakura.jp/eng/access/ , is there an information about "Fuji shibazakura go" JR Chuo line, direct Rapid train runs On May 1,4,5,7,8, 14,15 but unfortunately there is no detail about that in the website.

Could you give some detail about that ?
is it cover by JR Pass ?

Many thanks in advance

Agung
