Sanyo Area Pass

This may be a silly question but I just want to be sure. I'll be travelling from Osaka to Hakata, Fukuoka on end March. Here is my planned itinerary :

Day Destination
1 Osaka
2 Mt Koya
3 Mt Koya
4 Osaka
5 Osaka
6 Himeji
7 Fukuoka, Kawabata
8 Fukuoka
9 Fukuoka, Kansai Airport

I presume that the 4 days Sanyo Area pass will be worth it from Day 6 - 9?
