Suggestion needed of the JR Pass :)

Hello!

We (2 people) are traveling to Japan in april - may 2024 for 20 days. We have the following itinerary:

Day 1 - 6: Tokyo
Day 7: Traveling from Tokyo to Takoyama (thinking about traveling through Nagoya)
Day 8: Traveling from Takoyama to Shirakawago
Day 9: Traveling from Shirakawago to Kanazawa
Day 10: Kanazawa
Day 11: Traveling from Kanazawa to Naoshima
Day 12-13: Naoshima
Day 14: Traveling from Naoshima to Kyoto
Day 15-17: Kyoto
Day 18: Traveling from Kyoto to Osaka
Day 19-20: Osaka

We like the idea of the JR-pass, it seems very easy to use! But we're not sure if it's fits are itinerary. We look forward to advice and suggestions from JR-pass users!

Thank you!
