After you finsied climb Fushima Inari....I don't think you got stamina to go Arashiyama already unless you are very very fit.
Most common will be visit Arashiyama first. Can be done both places as long it was not at Winter Season. Winter season day light are very limited. 4.30pm already getting dark.

As long you do homework, know the public transport well......No problem.

actually, all depends on what you plan to do at any particular space. So when you ask whether can fit or not, do state what you plan to do there. From there only we can advice.

still vague. for example, at fushimi inari, are you going to hike up the hill? or at arashiyama, are you going to take the sagano train, or visit the monkey, or explore all the temples? Else, if touch and go, i can say you can even cover fushimi inari, arashiyama and golden pavi in 1 day.

brekkie?
most of the shops there don't really open till 9am, if i remember correctly (i went quite early too, can see them opening)

correction, shops start business at 9am typically
just checked back my photos, i went there at 8.30 to "help" open shop

what date u flying? im also flying in Osaka on Jan 2016 

I went Universal Studio Osaka on early December (when Winter started) and enjoy so much as is cooling but not sure February is freezing or same. But during the day we went, there was slight rain here and there, and it was indeed an experience where it rain icy water suddenly while myself and my son still on the ride in the air. 

If you really planned to go during winter, do be the earliest customer and make full use of the park operating hours, as they closed early. We were so reluctant to leave the place, hence after the park closed, we had our dinner at the Hard Rock (across the entrance) and after that return to the park gate and snap few more pics (in the dark).
