I just got back from a business trip to Osaka, Japan. Unfortunately, I was in meetings the entire visit so I couldn't tour the sites. It was a great experience though since it was my first time in Japan. I learned a great deal about their business etiquette and culture. Flying to and back from Japan in the same week does a number on your body. I'm hoping to go back to Japan in the fall for more than a week and hopefully Bryan will be able to join me.
By the way, being allergic to seafood is a bad idea if you're visiting Japan.
I'm already anticipating potential food issues when we travel to China to pick up our daughter. Thankfully, I know a few Chinese people that can make me allergy cards in advance of our trip.
