Got the message today.
Glad my boss didn't send me for training during the period.
I can start planning to stay over a week in Tokyo as a backpacker.
Only few problems need to be concerned:
1. Grab the ticket! (peak toursit season 
)
2. Japanese, Japanese....
3. Money, money, money
Luckily, I have nearly a month to prepare and friends from Real Hoon are willing to help me and give me a lot information. I'll try my best not to miss out this time.
(I aready missed out N times ....If I can choose, I would really love to go to the concert or dinner show, but it's impossible, unless I want to get fired! 
)
There will be lots of things need to be done for this trip(・ω・)/
Isn't that wonderful to have something looking forward to?
