We are travelling from Hakodate to Fukushima (changing at Sendai) on 28th March.
1) Can somebody confirm whether our JR Pass will be valid on this date? This website http://www.jreasthokkaido.com/e/index.html says it is launching only from 1st April, which is confusing.
2) Only Shinkansen 'Hayabusa' are operating on that day (at least at the times we want) http://www2.jrhokkaido.co.jp/global/english/shinkansen/ttable.pdf. Will we have to pay any additional fares to ride this train with our JR pass?
