Yokohama - Sushi museum near Shimizu - Tokyo

Pleas advise the cheapest transport option from Yokohama to Shimizu, then from Shimizu to Tokyo.

It is easiest to go in the Tokaido Line local train.
Time in less than most.
Is \ 2590 one way.
The other, Eiraku-cho to high-speed bus from YCAT
\ 2680 one way. \ 4,400 round-trip discount.
Perhaps not ride if there is no reservation.
Bus has come out Shimizu Station from Eiraku-cho, but it seems to go even about 30 minutes on foot.

I commented now, round-trip discount does not hear that it is Yokohama and Tokyo.
Was wrong.
If you go to Tokyo, those who transfer to Odakyu Odawara Station if Shinjuku if it may be cheap.

In order to go on to Shimizu Station from Yokohama Station, it is 2,590 yen aboard the JR Tokaido Line.

There is a bus to go to Shizuoka from Yokohama via Shimizu(Eirakucho), but not recommended because they are operated in the afternoon.
Fare to Tokyo Station from Shimizu Station is a 3,020 yen via JR Tokaido Line.
Fare of bus go to Shinjuku Station departed Shizuoka via Shimizu(Eirakucho) is 2,780 yen.
If you want to keep the seat, use of the bus would be good traffic to get back to Tokyo.
