Transportation from Sakurashimmachi

I will be staying for 3 days near the Sakurashimmachi station. I know that i must use the Tokyu-Den-Entoshi Line to go from this station to the Shibuya station. i wanted to know which pass (if any) i should buy in order to go around Tokyo, i.e like the 2 day Tokyo metro open ticket? does this or any pass cover the trip from Sakurashimmachi station to the Shibuya station?
Thank you.

A Suica prepaid card is likely your best option.

does this or any pass cover the trip from Sakurashimmachi station to the Shibuya station?

No.

As i read before the 2 day pass costs 490 yen per day=980 yen.
won't this pass save me monyey? cause after only normally 4 rides i will have to pay 480 yen.

But it covers only the Tokyo Metro lines. Not all the other lines. And are you really going to use the Tokyo Metro four times per day? If yes, then go for the pass. But many tourists will want to use other train lines and don't use subways more than four times per day.
