In 1991, young Dentsu employee killed himself in a similar circumstance.[19] After this incident, there was order from the Supreme Court in 2000 toward Dentsu to improve working conditions.[20] Matsuri Takahashi's case proved that Dentsu's corporate environment haven't changed since the death of its employees in 1991. Dentsu blamed Matsuri Takahashi's case partly on a serious lack of manpower in the growing divisions, such as internet advisement. The CEO of Dentsu made an announcement to the public saying, "We should have come to grips with the situation by increasing the number of staff in those divisions".[21] In Japan, lifetime employment still remains in numbers of companies and therefore, it is difficult to hire and fire people depending on the company's needs.[22] This CEO's quote indicates Japanese social structure which is stable but have low mobility which may cause stress toward employees.
