Useful Information for Life in Heisei Japan is a collection of knowledge on Japan that has been passed down within everyday living. It includes Japanese culture and traditions passed down since ancient times, and manners, covering a wide scope of areas, including traditional events, life customs, words and phrases of the four seasons, and the wisdom of everyday life. This knowledge is useful not only for Japanese people themselves, living in Japan, but is also a great collection of cultural information unique to Japan, which will be fascinating for people studying Japanese language or culture abroad. It is a virtual treasure trove of information on Japan.
The contents are based on the Manner and Common Sense Encyclopedia that is included as a supplement to the 2007 Encyclopedia of Contemporary Words published by JIYUKOKUMINSHA, and the Calendar of Conventions for Each Month: Enjoying the Seasons with All Five Senses, which was included as a supplement to the 2008 edition.
