Japan Diabetes Market Trends:
Rising Diabetes Prevalence
The growth of the diabetes market in Japan is driven by the rising incidence of diabetes. According to the International Diabetes Federation (IDF) reports, with 93,187,400 individuals in the country as of 2021, the prevalence rate of diabetes is 11.8% or 11,004,999 cases among adults. As a result, the market is expanding due to the increasing need for complete diabetes care solutions, which include cutting-edge drugs and monitoring equipment. Moreover, pharmaceutical businesses and healthcare professionals are compelled by the increasing number of patients to create and offer a wide array of treatment alternatives that address the diverse demands of their patients. In addition, the rise in diabetes cases has increased diabetes-specific healthcare services that attempt to enhance patient outcomes and quality of life. Hence, this trend has propelled the sales of anti-diabetic medications and boosted the market for innovative glucose monitoring technologies that promise more accurate and user-friendly options, thus creating a positive Japan diabetes market outlook.
Growing Geriatric Population
As reported by the Ministry of Internal Affairs and Communications, Japan's elderly population, those aged 65 and above, reached 36,227 thousand as of September 15, 2023. Moreover, the proportion of seniors in the overall population increased by 0.1% points to 29.1%, the highest percentage ever recorded. Additionally, the elderly are more susceptible to type 2 diabetes, which escalates the need for specialized diabetes management programs and products. This change in the population motivates healthcare organizations and clinicians to concentrate on the treatment of geriatric diabetes, resulting in advancements in medication therapy, nutritional guidance, and patient education customized to the needs of the geriatric population. Besides, the aging population influences several services and products that are in demand, offer simple use and low invasiveness, which are ideal for senior patients, and increase the volume of diabetic treatments that are necessary.
Supportive Government Initiatives and Healthcare Spending
The diabetes market is driven by the government of Japan's aggressive approach to healthcare spending, which includes a sizeable budget for treating chronic illnesses like diabetes. According to Frontiers, in 2020, Japan's national medical spending skyrocketed to 43 Trillion yen (304 Billion USD), nearly doubling from past figures since 1990. This indicates an increase in the nation's gross domestic output from 4.6% to 8.0%. In addition, the government ensures that enough money is spent on diabetes care, which makes treatments more accessible and reasonably priced. The foundation of diabetes care is being improved due to these programs, which cover everything from sophisticated treatment choices to primary prevention. In addition, numerous government initiatives concentrated on screenings and public health campaigns to lower the prevalence of diabetes while improving its management at the community level are influencing the market growth. Hence, these comprehensive health policies support Japan diabetes market growth by increasing awareness and early detection while integrating advanced diabetes care into the public health system.
Japan Diabetes Market Segmentation:
IMARC Group provides an analysis of the key trends in each segment of the market, along with forecasts for the period 2025-2033. Our report has categorized the market based on segment.
Breakup by Segment:
• Oral Antidiabetics
• Insulin

Insulin accounts for the majority of the market share
The report has provided a detailed breakup and analysis of the market based on the segment. This includes oral antidiabetics, and insulin. According to the report, insulin represented the largest segment.
Insulin reflects a substantial portion of the market share due to the increasing prevalence of diabetes among the aging population and the rising adoption of insulin therapies for effective glucose management. Additionally, Japan's healthcare system, renowned for its efficiency, extensively supports diabetes care, enabling widespread access to insulin treatments. Moreover, the market benefits from advancements in insulin formulations and delivery systems, which enhance patient adherence and outcomes. Besides, the Japanese government's proactive health initiatives aim to improve diabetes awareness and screening, further driving the demand for insulin. Furthermore, this segment's growth is also fueled by collaborations between domestic pharmaceutical companies and global diabetes care leaders, aiming to innovate and expand the availability of cutting-edge insulin solutions tailored to the unique needs of Japanese patients. Hence key players are introducing advanced product variants to meet these needs. For instance, in March 2023, in Tokyo Japan, and Taipei, Taiwan, Health2Sync, announced the recent update of its Health2Sync App now including insulin data from the Mallya Cap, a connected device for insulin pens created by Biocorp and marketed in Japan by Novo Nordisk. This collaboration introduces the world's first integration of this type of data and is designed to aid patients undergoing insulin treatment by tracking various health metrics, such as insulin injection records. Due to these innovations, the Japan diabetes market forecast states that insulin segment will continue to dominate the market.
