14 Days JR Pass vs individual Tickets

Hello,
We plan to visit Japan from 14th of February 2025 to 28TH February 2025. We are 5 people.

We have a plan as below:
• Osaka (14 - 16 February). • Hiroshima (16 - 17 February). • Miyajima (17 - 18 February). • Kyoto (18 – 23 February). One-day trip Kyoto–Nara –Kyoto (12 February). • Takayama (23 - 24 February). • Takayama - Shirarkawago – Kanazawa (24 February). • Kanazawa (24 - 26 February). • Tokyo (26 - 28 February).

We need your advice to know which is better, using JRPASS or buying individual Shinkansen tickets.

Thanks in advance.
