Kairakuen/JR Kanto Pass Question

Hello - I am going back to Tokyo for a couple of weeks at the end of Feb/beginning of March, and while I'm there I'd like to see some plum blossoms. As well as in Tokyo itself, I've been been debating going to a festival in Shimisoga (near Odawara) or at Kairakuen for a day trip.

I've checked the page about Kairakoen on here and also at the garden's own website but I can't find a definitive answer so I thought I would check here. Can Kairakoen be reached on the express trains from Ueno using the JR Kanto pass? (I do have other day trips in mind, and I am trying to work out a three day schedule to see if the pass is worth it for me).

Yes, Mito and Kairakuen can be reached by JR limited express trains from Ueno that are fully covered by the Kanto Rail Pass. See the map on the following page:

Thanks Uji! I had looked at the map, but it seemed such a potentially great deal using the Kanto Pass that I feared it was too good to be true!
