This site carries the information you need for daily life in Japan, written for professionals assigned to Tokyo from overseas and for the families who come with them.
It is made up of Japan Basic, which covers society, the economy and city data; the Living Guide, for the practical knowledge and customs of everyday life; and the Tokyo Area Guide for what is specific to Tokyo. Together they cover what is worth knowing before you arrive and what keeps proving useful once you are here.
Access to this site is limited to closed environments such as a company intranet or a members-only site. It covers local healthcare, schooling, safety and other information needed for an overseas assignment.
