Central Tokyo to Chidoricho Station

Hi all,
There was a similar question by someone else on here but they already had a valid JR, I won't when I need to do this train trip. On our third night we will be wanting to stay further out of Tokyo at the Ryokan Kangetsu near the Chidoricho station. Our JR pass we will not be to validating until the day after that (10 day trip, buying a 7 day pass), but we will have a Tokyo Metro pass (as part of the 2 day Limo and Metro Ticket deal) and I'm wondering if that Metro ticket will get us from central Tokyo out to Chindoricho station or do I need a JR ticket for part of the trip?

Chidoricho Station is located along the Tokyu Ikegami Line which is not covered by the Metro Pass nor the Japan Rail Pass. But we are talking about a train fare of just a few hundred yen.

Exact access details depend on your departure station. You can look up possible routes yourself on the following website:

Great. Thanks very much. I have no idea of distances etc so this is all very confusing. And I thought Sydney was bad! It has nothing on Tokyo!
