osaka has usj...kaiyukan...cup noodles museum...osaka castle...one day to visit all isn't possible...
same goes to kyoto

suggest to just stay within osaka and maybe a day trip to nara

not recommended as it will be a rush... shin osaka is not like our KL sentral, it is huge and crowded on mornings + you are expected to be blur for a while to get familiarized - by then you wasted some time.

If you truly want kyoto only, please sleep at Kyoto - it will save you alot of time.

P/S : once you reach Kyoto remember that you still need to take bus/subway to your destinations !
Edit : I have a question too, anyone experienced visiting Tokyo Disneyland a day before or after publc holiday at Japan? Or is that place 365 days same crowded like USJ?

Tokyo Disneyland got low season. You can refer to my Tips of the months Excel Helicopter ride. Around July are less people. So less people until like ghost town.  Really depends luck.
Day 1 can visit Umeda Area for Dinner + Umeda Sky Building after dinner leisure time. Not far away from Shin-Osaka Station.  [[Take Midosuji Line Metro]]

Day 2 Go very early morning. Must reach Fushimi Inari before 8am.  Then Visit Kiyomizu -Dera. Last Kinkakuji.  Dinner at Nishiki Market.
After Dinner, have a peaceful walk near Sanjo Station.  Walk along river.  Supper at Famous Pontocho Alley.

Day 3 From Osaka Namba Station take Kintetsu Nara Line to Nara.  Make it Full Day.  Dinner at Namba area.

Day 4 No problem. Follow your plan as you wish.

Day 5.....Please Reach Kansai Airport 3 Hours before your flight.  2 - 5pm are Kansai Airport most busiest time.  Custom Q are extremely long.

This is a good question. This JR Yamatoji Line start from Kamo Station all the way down to Tennoji Station. Then It will share using the JR Loop Line to Shin Imamiya Station.
Most of JR Yamatoji Line Train stop at Shin Imamiya Station.
Only ''Yamatoji Rapid Service'' JR Yamatoji Line Train continue from Shin Imamiya to Imamiya Station. This mean ''Yamatoji Rapid Service'' train will be start from Kamo Station to Imamiya Station.
Only ''Rapid Service'' will reach Namba Station from Kamo Station.
It can be done.  I done this way more than 200 times.
Last train leaving Kyoto Station to Shin Osaka Station are 00:15 [[JR Kyoto Line]]
Please Used Google Map. All Places start from Dinner to supper are very closed each other. All walking distant

Thank you very much. Your advice is of tremendous help to us. We faced a lot of hassle trying to draw up the itinerary.

Actually we just need the bare minimum data to surf for locatons n direction.
Sifu your suggestion will be most appreciated.

hi guys, 2 main questions need help please:
1. do most of you buy travel insurance when visiting japan? if so, which one?

2. travel method from airport to hotel and around kyoto/osaka. please let me know if this make sense.
- buy icoca + haruka combo from (http://www.westjr.co.jp/global/en/ticket/icoca-haruka/)
- reaching japan : use haruka to travel from KIX - kyoto hotel (kyoto station)
- during stay at japan : icoca card to travel around kyoto/osaka by subway, buses
- leaving japan : use haruka to travel from osaka - KIX

are you into temples?
your time should be about right to see autumn colours
many great place to do that but mainly in Kyoto - Kiyomizudera and the area around it, Kinkakuji all the way to Arashiyama Bamboo Forest and the Sagano railway from there, the Ginkakuji to the Philosopher's Path, the Fushimi Inari, Uji, etc

There will be a festival going on in Kyoto on the 22nd of October, the Jidai Matsuri.
It could be a interesting experience for you.
