How can I tell which stations and trains accept JR pass

Hi, I am using google maps and each search shows about 2 connections between each city, often with different trains and companies. Only some are Shinkansen or have a JR symbol. How do I know if the others accept JRpass?

Example: I search for Tokyo to Hakone and one option gives this list of companies under ticket and information:
Hakone Tozan Railway
Keio Corporation
Odakyu Electric Railway Co., Ltd.
Jorudan - Transport Data Producer

Is there a more suitable site than google for JRpass holders to plan trips?

Thank you
