Amakudari is the practice of senior government officials retiring to high-ranking positions in businesses or semi-public organizations. Upon retirement, they receive large severance payments and are immediately reemployed by entities with strong ties to, or under the jurisdiction of, their former employers. Since the environment thus created is generally perceived as a breeding ground for business-government collusion, the word “amakudari” has negative connotations. 意訳：高級官僚が退職後，勤めた官庁と関係の深い民間企業や半官半民の機関などに再就職し，重要なポストに就くこと．官民の癒着という点で，また，すでに多額の退職金を手にしたあと再就職するということもあり，「天下り」という言葉には批判的な意味合いが込められている
