According to the Ministry of Health, Labor, and Welfare's report on changes in real average salaries, 4.65 million yen in 1994 was less than 4.33 million yen in 2018; when the salary level of male regular workers in 2021 is set at 100, that of women is 75.2. The number of people receiving comprehensive medical examination (Ningen Dock) has remained stable at around 3 million since 2003 until 2014.

 As a voluntary medical checkup, the standard test items that should be performed as a physical checkup are defined; a survey conducted in 2013 reported an average cost of 44 thousand yen. In addition to this, women need a cervical cancer test and a mammography test.

 The Ningen Dock has the feature of being able to be completed in one day, including statutory cancer screening and specified health checkups, and provide explanation of results on the same day. Under the economic situation described above, it is expected that a minimum level of physical checkups will be formulated to make it easier for more people to receive examinations.

 There have been many scientific validations of the items to be tested in health and medical examinations, including Recommendation by the United States Preventive Services Taskforce, Choosing Wisely, and the Ministry of Health, and 18 requirements by the Ministry of Health, Labour and Welfare of Japan. Based on these, we reviewed the current standard examination items and devised a minimalist physical examination system that omits unnecessary items. Retaining the statutory examination items, the "Minimum Ningen Dock" can be offered at a lower price through six types based on gender and life-stage disease status. This is expected to make it easier for many citizens to receive medical examinations. In addition, the Ningen Dock Choosing Wisely has been formulated.
