Hakone Free Pass Coverage

Dose the Hakone Free Pass cover the Hakone Open Air Museum? Or does it just give a discount. I checked the web site but couldn't understand if it was full coverage or not.

The only sightseeing spot whose admission fee is fully covered by the Hakone Free Pass is Gora Park. For the Open Air Museum, the pass provides a 200 yen discount from 1600 yen to 1400 yen.

All discounts in Japanese:

Make sure to ask for the discount as there is no posting at the ticket counter. Make sure to check the listed discount attractions or ask.
You can go in free (show the pass) to the Sekisho(old check point) Museum in Hokone-machi.

I believe that the pass provides only a 100 yen discount (from 500 yen to 400 yen) on admission to the check point museum.
