Today I finally went out and bought a digital camera! I went to the big Yodobashi Camera near Kawasaki NOVA and bought a Canon IXY 4 megapixel camera with a 256mb memory card. I was looking for something in the 4 megapixel range with optical zoom that was point and shoot. This camera met all of my requirements, and the price was pretty good too.
I managed to make the entire purchase using Japanese. Very simple Japanese, but I still felt pretty proud of myself. The salesperson was very polite and patient. Yodobashi Camera rules!
