20 Day trip to Japan

Hi there!
I am planning on visiting Japan in June of 2023,
My current plan is:
Arriving at Narita Airport 06/07/2023
Narita-Tokyo 06/07/2023
Tokyo-Toyama 06/12/2023
Toyama-Kyoto 06/14/2023
Kyoto-Osaka 06/17/2023
Osaka-Tokyo 06/21/2023
Tokyo-Narita airport 06/27/2023

I am so excited to experience the culture I just feel so lost when it comes to scheduling travel especially through trains.

I was thinking about getting the 14-day rail pass on the 7th and then have that last me until I get back to TYO. I would then bite the bullet on the airport train back to NIA.

Thank you so much,
Jake
