Vacation Planning - Multiple Countries in Asia

Im asian and I'm going to asia!

Here's my high level plan and flight itinerary, although I haven't planned out the day-to-day details of the trip yet:

• LAX to Osaka (with 8 hour layover in Tokyo): leave work Friday afternoon at 2osh, take off at 440pm, land in Tokyo at 1030pm of Saturday night for 8 hour layover, go clubbing/roaming/shopping till dawn, take flight to Osaka. Don't sleep and visit Osaka on Sunday. Visit Kyoto for 2 days, take train to Tokyo and hang out there for 3 days. Leave Tokyo a little before midnight on Friday, after having spent 6 days in Japan.
• Tokyo to Kuala Lumpur (7 hr flight, sleep on plane): arrive in KL around 6am. Check out KL for the day, leave KL at 5pm for Singapore.
• KL to Singapore (1 hr flight): arrive in Singapore, probably go clubbing. Spend 2 days in Singapore till Tuesday late night, fly to Hong Kong
• Singapore to Hong Kong (4 hr flight, sleep on plane): get to HK on Wed morning. Check out the city/go clubbing, etc, till Friday night. Fly to shanghai.
• Hong Kong to Shanghai (2hr flight, 7pm to 9pm): See my relatives. Stay inside, stay at home, spend time with my grandpa.
• Shanghai to LAX (1hr layover in Seattle. I could've selected a longer layover and check out Seattle a bit, but the flight lands monday morning at LAX at 10am. I'm going straight back to work)

I'm kinda jk about doing all that clubbing by myself. (Maybe)

Here's the rest of my detailed planning (worthless, dont read this):

Here's a boring discussion on how i bought plane tickets(also worthless, dont read this):

My way of doing trip planning is to plan out the big stuff (buy the big tickets for the big cities i know i'm going to hit) and then plan out the details when I have time or when I get there. (Kind of like that that analogy about how in order to fully fill a jar, you fill it with big rocks, then little rocks, then sand, then water). I guess that's how everyone does trip planning. Or is it? (how do you do trip planning?)

I kind of first list out the requirements of must-sees from using http://www.tripadvisor.com/. Then I find tours/plan routes to hit up those must-sees. http://www.tripadvisor.com/ is a great resource because it ranks attractions.

It turns out that I'll end up spending about 3 days per destination with a population of 5-7 million people. I guess that's fair.
