Japanese Slang
This dictionary is a comprehensive and in-depth look at all the slang, vulgarisms, curses, and insults, plus idioms and expressions and a lot more, available in Japanese. Every effort has been made to keep it current and relevant, though of course older slang also remains in here for those who enjoy films, television, and books from years past. If you like anime or other modern Japanese entertainment or are planning to live, work, or travel in Japan, you'll find many of the words and phrases used in here. As always with slang, be careful using what you hear; it may not work quite the way you expect.
