itirenary for 4 days FEB 10-14, 2015

I'll be in Japan for 5 days 4 NIGHTS . I'll be flying to & from Nagoya. My rough plan is as follows:

Day 1 AM : Nagoya to Osaka =BACK TO NAGOYA
Day 2: NAGOYA -Osaka BACK TO NAGOYA
Day 3 NAGOYA =TOKYO
Day 4: NAGOYA- KYOTO

     Evening flight from Nagoya.= TO MANILA 

Will JR pass be worth buying for this trip? Please advice..

Thanks!
