My last day itienary in japan (osaka)

I will go to japan in april 20th to 29th.
and my last day will be in osaka.
my flight in 29th is 11PM. and i have whole day in osaka.
im planning to go to Namba area in the last day. but here's my question :
1. My hotel is in kita-umeda area and i have 1 big suitcase and 1 backpack. its impossible to carry those with me during the day.
im planning to take them into KIX in the morning so i can store that in the airport and go back to osaka again to enjoy my last day. is this possible?

2. My first plan is to visit namba area until afternoon 12PM-1PM. after that, im planning to spend the rest of the day either in Osaka aquarium or USJ. which one is the best choice? since i have time from 2PM-9PM?
and i know its in golden week but its monday. is it still crowded too?

thank you.

Hi
You can use a takuhaibin service to transport your luggage from your hotel to the airport.

hi fuchan29
i wonder where i can go to the takuhaibin service in osaka? and is it safe?

Is it an option to ask the hotel to hold your bags when you check out and collect them in the evening on your way to the airport? We normally do it that way and find it works for us as the home flight for us is also late evening.

Hi
One day before you leave, just ask at your hotel.
They organize the arrival of takuhaibin.
Maybe your luggage will be taken in the evening before your departure.
No problem for your luggage, they will be in safety.

If you do not know what to do with your last day in Osaka, here are some ideas ...

I suggest you go to Tennoji visit the area around the tower Tsutenkaku
This is the "deep Osaka."
