tenar,
Congratulations mummy!
My Dr ordered heaps of blood tests when I went to him. There was the usual to confirm pregnancy, progesterone levels, Hepititis, HIV, Cystic Fybrosis, Toxoplasmis, Rubella and may some others. Turns out the only thing I had to worry about what the toxoplasmis. Turns out I wasn't immune even though I had a cat for years. Just as well I re-homed my cat about a few months before we decided to TTC.

As for Japan, yeah I think you will be pretty safe there as long as you make sure everything you choose is cooked and served hot. Not cold chicken or deli meats. Nothing raw and no uncooked fish... If your like me I would be getting into the rice. Chances are you might end up starting to feel the effects of morning sickness and wont feel much like eating anything exciting. But cross fingers that side effect will not come knocking at your door, especially while your away. Cause it will be the smells that will most likely get you started.
