I have been thinking of taking my spouse to Japan for our anniversary.
You mean the sovereign island nation in East Asia, Japan? I would highly recommend it! Do you know much about the area?
Im not sure we love arcades and bars and he has heard about the Namco Arcade that is world famous. So we will be going in that area.
Cool! That would be a lot of fun! Also, if you're interested in outdoor activities, Japan is what's called an "stratovolcanic archipelago". There are about 6,852 islands there! Do you like outdoor activities? 
I would be interested in some while we are there!
Great! I hope you're not shy though, Japan has the 10th largest population in the world. About 127 million people! Have you ever visited a place like that before?
