Few days in Tokyo and few days in Kyoto, really awesome place to visit. Since i'm too tired to write about it in length, ill just drop it down in point form.

For Tokyo:

• Sashimi, Ramen and street food are great! Since my favorite food is ramen, seems like every random ramen house beats the stuff i'm eating in Singapore.
• Harajuku and Shibuya is where the hot chicks are at. For Shibuya, go at night time, thats when the place is really busy. You don't need to go far for the spectacle, just outside of the Shibuya station near the busy crossing. Harajuku, go on sunday mornings. Thats when they are all dolled up and out to play. Some of them might not like having pictures taken unless you pay for that privilege....
• Go with minimal planning. Me and my boss just randomly walked around Shibuya to find a bar to have a few drinks. We ended up above a porn shop, through a stairwells no wider than my shoulder. It was fun meeting new local people.
• In Tokyo, check out the Park Hyatt Hotel. On the 52nd floor, there is restaurant called New York Grill. There is a cover charge if you don't live in the hotel, but it worth having a drink the bar area and enjoy the view. You might be lucky enough to catch some really cool live jazz music too. Photo of the bar and view at night.
• Avoid getting the cab if you can. Its pretty pricy to say the least. But also keep in mind that the last trains stops around 12:30am (i guess it depends on where you are hopping on the train). Cab surcharge of roughly 20% applies after midnight from what i have been told.
• You can also head towards Hamamatsucho station to get a better view of Tokyo. WTC building is right up there. Pictures here, here and here.
• Visit Asasuksa by either taking the train or take a cruise along Sumida river. That is where the Asahi HQ is and where the Senso-ji temple resides. Don't forget to try check out yourluck for the year.
• Check out an electronic dart bar if you have not been to one. My friend took me to this onein Ginza.
• If you have half a day to spare, take a short train ride to Ueno station, just 2 stops from Akihabara. Ueno has got a more traditional feel to it. Walk towards Shino-bazu pond and enjoy the many shrines along the way. Head back to Ueno township to check out the busy shops along and below the train line.

For Kyoto:

• Most of the attractions are around the city. Rent a bike. There are plenty of places to rent a bike, i got mine at the good people at J-cycle, for 800 yen a day. Starts at 10am to 7pm. Biking is pretty safe in Kyoto, just stay alert and do what the locals do, park where the locals park.
• I find that just cycling around the city without worrying too much of whether i am going the right direction, is actually really fun. You get to see alot more of Kyoto then just hitting the hot spots. Locals are very friendly and willing to help. If you dont speak much japanese like me, point on the map where you want to go, wait for 30 seconds of japanese, when the locals point, thats where you go.
• If you want to go for the Imperial palace, make sure you know when the tour starts. The last i checked, there is one at 2pm. 
• Gion district is nice to check out. And of course the temples along the east side of the city, mainly Kiyomizu-dera temple. Check out the philosopher's path for a nice ride through the center of town.
• Also not to be missed, with your JR pass, take a local train down to Inari station. Right on the exit, is the entrance to Fushimi Inari Taisha Shrine, with thousands of Torii gates up the hill. Climb to at least half way to get a awesome view of Kyoto city.
• There are plenty of buses starting and ending at Kyoto station, which will get you to alot of tourist destinations. 220yen each way if not mistaken.

There you have it. Tokyo and Kyoto in a nutshell. Just a reminder, it is really hot in Japan during summer, so bring plenty of shorts to walk around.
