Cherry blossom sighting in Mount Yoshino

Hi, I'm in Osaka on 18/4 and would like to make a day trip to Yoshino. Had bought JR-Sanyo pass and please advise how do I get to Mt Yoshino for cherry blossom sightings. Thank you.

From which place in Osaka City will you head to Mt. Yoshino?
Accesses by public transportation for and inside Mt. Yoshino are operated by non-JR companies.

Had bought JR-Sanyo pass

How is the rest of your itinerary? Have you checked the JR West pass can pay off?
Anyway, you cannot directly buy a JR West pass itself outside Japan; if you have bought something concerning a JR West pass through one of the authorized travel agencies, it must be an Exchange Order.
