JR Pass & Suica

Hi

I'm planning an 9 day trip from Fukuoka to Osaka, including day trips from Osaka to Kyoto and Nara, then Osaka to Tokyo
I have already bought the 7 day JR pass but just wondering if buying a Suica card beforehand is worth it, and which areas it covers for my plan below (specifically if its ok for the areas in Osaka and Kyoto)

Day 1 Fukuoka kuko to Osaka
Day 2 Osaka Castle and Namba
Day 3 Osaka to Kyoto day trip - including Arashiyama, Fushimi Inari Taisha, Kinkakuji
Day 4 Osaka to Nara day trip
Day 5 transfer Osaka to Tokyo (Shinjuku)
Day 6 Tokyo - Harajuku, Shibuya.
Day 7 Tokyo - Tsukiji, Ginza, Tokyo Station area
Day 8 Tokyo - Asakusa, Tokyo skytree
Day 9 Narita airport transfer bus

Thank you in advance!
