The subway is very easy to navigate and definitely the best way around. Taxi's work as well but will obviously be more expensive. You may also have a language barrier so you may need to have your hotel write where you are going on a business card for you so you can give that to the driver. We did that a few times. If i recall some cabs will take credit card and some will not. So you will want to have cash handy. I cant recall whether Amex was a problem.Timely bump, my wife and I never made it there. However, looks like I am going to Japan for work for about a week. What's the best way to get around Osaka and Tokyo? Can I just do taxis from my hotel to my meetings and back? Do taxis take AmEx or do I need to get Yen?
How about travelling from Tokyo to Osaka... bullet train or fly?
And when going from Tokyo to Osaka, definitely take the bullet train. Its very easy and will be much cheaper.
