Hakone-Uno with JR pass

Does anyone know the best way to get from Hakone to Uno/Naoshima in one day with a JR pass? I've done a couple of searches on HyperDia and they suggest it will be a complex, multi-stage trip. I was just wondering whether anyone has thoughts on the most efficient route. Thanks

I don't know exactly where in Hakone you want to start from, but in any case, you'd need to get out to Odawara, change to JR Shinkansen and go to Okayama, then take Marine Liner to Chaya-machi, then take Uno line to Uno. No matter what, it will take 5 - 6 hours one way.

Whoops, I missed that you specified you would have a JR Pass. That is why you need to change Shinkansen trains a few times to get to Okayama, because there are some Shinkansen trains that you cannot take with the Pass.

This is.

JR-Pass not covered Hakone area. (No JR rail/line)
Also not covered Nozomi/Mizuho(fastest shinkansen name) until Okayama.
