I'm very excited that there is a Japanese version of lastminute.com - http://www.lastminute.co.jp/.
Americans may be unfamiliar with this UK-based service, but it lists lots of great deals on travel and entertainment for those of us who find ourselves planning things a day or two before we want to do them.
Planning things the day before - sounds perfect for me!! Thanks for the link.
Lastminute.com can be a bit addicting. When it first came out in the U.K. we would constantly scan it and often take up on some of the irresistable deals. Good luck bargain hunting!!
