Cool Japan
Japan has been famous for a hard-working society with little time for entertainment, however Japanese entertainment culture has become very popular around the world. Cool Japan is a term used among foreigner who are attracted by Japanese entertainment culture such as anime, comic (manga), fashion, music and so forth.
Cool Japan does not reflect the modern Japanese pop culture, but also traditional Japanese culture such as samurai, ninja and so forth. In fact, many popular Japanese comics (manga) illustrates traditional Japanese life and many foreigners are attracted by these mysterious Japanese tradition.
Of course, Japanese pop culture is a main driver for recent feat of Cool Japan. For instance, cosplay (wearing a costume and pretending to be a dream character of favorite anime or comic) has increasing become popular in Japan and many foreigner think cosplay is lots of fun and cool. There are some big cosplay event mostly held in central Tokyo and a lot of foreigners come all the way to Japan to participate in the event wearing their favorite character costume. I used to try on Gundam Char's costume which is known to be one of the coolest anime character in Japan, but unfortunately friend of mine just kept laughing at me
