I hope the itinerary is helpful for those in need as we planned our trip by referring others' itinerary too.
Below are the itinerary:
Day 1(5/12/13)
We boarded a flight on the we hour, so we reached KIX around 9 a. m.
From KIX, we took train to Kyoto (Kawaramachi station) with Kyoto Access Kippu Ticket.
On the journey, we had to change line for 3 times.
We checked in at Kyoto Khaosan Guesthouse. It's a very nice guesthouse. It's cozy and affordable.
Six of us stay in a dorm with 6 bed. The guesthouse has kitchen for us to cook.
Dorm:
The guesthouse has wi-fi access and pc to use. And the guesthouse provide a lot of information around tourist spot in Kyoto!
This is the living room in the guesthouse. We can watch tv, rest and online in this place.
We had lunch at a Japanese cuisine restaurant around the guesthouse. 
We spent our day around Kyoto and Teramachi shopping arcade.
Day 2 (6/12/2013)
On the second day, we decided to have sight seeing around Kyoto. So we bought Kyoto City Bus One-day Pass cost 500 yen.
To Kiyomizu Temple
Kyoto Imperial Palace
Ginkakuji Temple
Nishiki Market
ps: If you think you are missing, ask working foreigners. They speak English and know the direction of the places well.
Day 3 (7/12/2013)
On the third day, we decided to stay in Osaka.
We took subway, from Kawaramachi station (nearest station of the guesthouse) to Umeda Station cost 390 yen.
From Umeda st , to Namba st cost 230 yen.
Lastly, from Namba st to Tennoji st (Our hotel locates) cost 230 yen.
There are different lines of subway, such as Midosuji Line.. etc. Is quite confusing at first, but we managed to overcome by the use of subway line map. It's very useful, because it shows you all the subway line and stations. Make sure have a map in your hand.
And you will notice there is different type of train. They have the same origin and destination, but some of the train just stop at certain station, some of the train stop at all station.
Namba and shisaibashi are famous for shopping and food as well.
