A Finance Ministry expert panel and the Japan Innovation Party have proposed a uniform 30% medical co-payment for all citizens aged 70 and over [1, 2].

The proposal aims to sustain Japan's national health-insurance system by reducing the financial burden on the working generation. Proponents argue that shifting more costs to seniors will ensure long-term fiscal balance, and lower insurance premiums for younger workers [1, 2].

Under the current system, co-payment rates vary by age: those up to 69 pay 30%, individuals aged 70 to 74 pay 20%, and those 75 and older pay 10% [1]. The new proposal would standardize this rate at 30% for everyone 70 and older [2]. For some seniors, this change could result in out-of-pocket costs increasing up to three times [1].

Expert panel discussions regarding the measure took place on April 28 [1]. Supporters suggest that improving the quality of medical services alongside these reforms could lead to fiscal savings of several trillion yen [4]. A spokesperson for the Japan Innovation Party said, "The pillar of this is to make the window burden for elderly medical expenses 30% in principle" [2].

However, the proposal faces significant opposition from government officials. Health Minister Kenichiro Ueno said that raising the medical co-payment for those 70 and older to a uniform 30% is not realistic [3].

Critics of the plan warn that higher costs may lead to a decrease in medical visits. This trend could increase the risk of patients developing severe conditions due to delayed treatment. Some advocates for the elderly have called for the inclusion of specific relief measures for low-income individuals to prevent them from avoiding necessary care [1].

The proposal aims to sustain Japan's national health-insurance system by reducing the financial burden on the working generation.

This proposal highlights the growing tension in Japan's social security system as the population ages. By attempting to shift the financial burden from the shrinking workforce to the elderly, the government is weighing fiscal sustainability against the risk of reduced healthcare access for vulnerable seniors.
