Pass in Hokkaido and Tokyo

Hi there, appreciate if anyone can give me suggestion.

We will go to Hokkaido for 4 days and Tokyo for 6 days.

Hokkaido trip, stay in Sapporo. we will go to Otaru, Niseko, Furano, Ashikawa, Noboretsu.
= 4 days are enough to visit those city?
= What train ticket pass should we purchase? Does JR Pass cover all in Hokkaido?

While in Tokyo, we plan to be in town for 4 days, and another 2 days to go to Niko (on new year's eve). Is it worth to buy JR Pass?

Any activity on Nikko on New Year's eve? Onsen open or close?

Thanks.

It's well worth getting a 7 day pass provided that you include your Nikko trip in that 7 days.
This gives you the option of using shinkansen to get there.
If that's not how you want to set it up get a 4 day Hokkaido pass and use Tobu Rwy to get to Nikko.

Thanks.
For 4 days in Hokkaido, 4 days in Tokyo and 2 days in Nikko:
= better take 4days Hokkaido Pass (covered Otaru, Ashikawa and Furano) + 7days JR Pass ?
= or take 4days Hokkaido Pass + Suica card for using in Tokyo + Tobu Rwy to get to Nikko

Which one is cheaper?

Nikko is one of the most esciting place I recomend.
Takeng Tobu Rwy is much cheeper to get Nikko.
You can't miss also the waterfalls not only Tosho-Gu Temple in Nikko.

I'm a Japanese studying English in Tokyo, so sorry if this message dosen't meke sense.

Should I also get the JR pass if I intend to take the shinkansen from Nagoya to Tokyo and include a visit to Nikko as well? Thanks

Thanks RodW.

While in Hokkaido, we will get 4 days Hokkaido Pass. This will cover trip: Sapporo - Ashikawa - Nakafurano - Furano - Noboribetsu - Otaru.
Question: Does this Hokkaido Pass cover Chitose Airport to Sapporo St?

While in Tokyo (for 6 days), we'll get Suica Card. And buy Tobu Rwy, to go to Nikko. We'll skip JR Pass.
