JR Pass for Tokyo, Osaka and Kyoto?

I'll be travelling to Japan in September with my family of 4 adults, including first 2 days in Osaka, then 3 days in Kyoto, then 2 days in Tokyo. What's the best transportation to travel between these cities? Does it worth buying a JR Pass to cover these cities?

Many thanks for any good advice.

I like this calculator for getting a rough guide to the value in a JR Pass. https://www.japan-guide.com/railpass/

Also, there are some Shinkansen deals with Japanican, which might be good depending on your needs: https://www.japanican.com/en/ticket/

Have a great time in Japan.

A 7-day JR Pass comes close to paying off with a round trip between Kansai and Tokyo. If you're not going back to Kyoto/Osaka, the pass won't be cost-effective.

Many thanks for your advice, folks. You all have a good day.

Cheers,

You are not doing a round trip, so single tickets is much cheaper.

My advice is to check your itinerary on Hyperdia to be completely sure that the Japan Rail Pass pays off. I recommend this because the pass is only worthy if you travel on long-distance trips. For example, on day trips. This guide may help you, as it's explained step by step how to use this transportation planning tool: https://www.jrailpass.com/hyperdia

Hope you enjoy the trip with your family!

You must buy Japan bus pass 7 Day=15000 yen cover Tokyo, Osaka
Kyoto etc prefecture unlimited time for 7 Days.

Many thanks again to everyone who responded. Have a good day.
