I love business cards, because I’ll admit it, I am not good with names. First names, last names, if you tell me, I will probably forget it. (Kirakira names are usually easier to remember though!) The good thing about living in Japan, however, is that despite there being over 100,000 different surnames, a really high percentage of people use only a few really common names.
To make it even easier for me, different areas of Japan often have higher densities of certain names. For instance, there are about 4,700 people in Japan with surname Maru (丸), but more than 50 percent of them live in southern Chiba. So, if you forget someone’s name in southern Chiba, Maru might be a safe guess.
A website and smartphone application called Myoji-Yurai Net allows you to find out the prevalence, origin and other fun information about the top 3,000 surnames in Japan. It’s actually quite fun!
