Using the 7 Days JR pass for other uses

I intend to purchase the 7 Days JR pass and seem fairly clear on its use for Rail Journeys in Japan.
However, I would like to know if this pass can be used for any other journeys like the Bus travels in Tokyo, Kanazawa - Shirakwago-Takayama trip or in Kyoto, Hiroshima or Osaka areas.
Inputs appreciated with Thanks

if this pass can be used for any other journeys like the Bus travels
I have used the pass for some JR buses, you need to check this information for the areas you are visiting.

There are some non-rail services that accept the JR Pass, yes. Read the conditions of the pass (available on this website and through a Google search) for specific details.

It works on JR buses, but not Express JR buses. Meaning it can't really be used to get between cities and most cities have their own bus network that isn't JR. So it's very limited and probably won't be useful to most people for bus travel.

It also works on the ferry to Miyajima, which can save you 500y.

It also works for the BRT (Bus Rapid Transit) from Yanaizu to Kesennuma on the old Kesennuma Line. The rail line between the stations was destroyed by the tsunami on March 11, 2011 and vast portions of the rail line were paved over and now a bus service operates between these two stations. Since it was a one track line, the bus is the only vehicle allowed to operate on the portions of the bus route that actually use the old rail line. There are stations along the way where one bus will stop to let the bus from the opposite direction travel by. It joins Route 45 in some places and it uses conventional roads when needed. The JR Pass works for this bus route if you wish to visit Minamisanriku from Ishinomaki or Kesennuma.
