The primary driver of growth in this market segment is the rising incidence of respiratory diseases, particularly asthma and chronic obstructive pulmonary disease (COPD). The smoking epidemic, as well as the rise in air pollution, and the overlap between asthma and COPD, which makes the diagnosis complex, are the significant drivers of this market. Together with the innovation of pulmonary disease drugs, the strategic partnerships that pharmaceutical companies are forming at the research and development level are driving their market growth.

According to the latest information from the Japanese Ministry of Health, Labour and Welfare, nearly 200,000 new cases of COPD are diagnosed each year. At the same time, this disease is also prevalent in 0.2-0.4% of the people in different age groups. The reimbursement support and measures the government takes to improve the respiratory health of the Japanese people are the drivers in the Japanese market.

Advances in inhaler technology are supported by the guidance of health professionals, who adapt treatment protocols through the use of digitally controlled inhaler devices. This, therefore, leads to the development of technically advanced medical technologies which are compact, easy to use, and comfortable, and these terms are repeated in the case of healthcare, which is innovation and convenience.

Key Trends

• Integration of Smart Inhalers: The incorporation of smart technologies into inhalers, such as adherence tracking and digital reminders, aids geriatric patients in adhering to their routines and is also associated with market growth in Japan.
• Target Market in Geriatric Healthcare: The high proportion of elderly population in Japan drives the development of inhalers specifically designed for older adults, which include custom reminders and adherence tracking, thereby prioritizing ease of use and precise drug delivery. Therefore, their use has increased and is used widely across the country.
• Innovations for Mother Nature: Manufacturers are reducing greenhouse gas emissions through the introduction of regulatory reforms that increase pressure to cut emissions. This has stimulated manufacturers to develop regulatory guidelines and adopt inhalers, shifting the market from pressurized Metered Dose Inhalers (pMDIs) to Dry Powder Inhalers (DPIs). They are looking for the new inhalers that reduce 99% of the greenhouse gases.
• Homecare Gains More Relevance: Portable nebulizers and other respiratory devices for at-home use are increasingly in demand in Japan since the country has moved towards home-based healthcare and long-term care.

Drivers of Growth

• Rising Prevalence of Respiratory Diseases: COPD and Asthma are key indications that affect a significant portion of the population over 40 years and above. With the high prevalence of smoking in Japan, there is an increasing incidence of asthma, COPD, and other respiratory conditions, driving demand for inhaler devices in Japan.
• Technological Advancements: The Development of digitally operated inhalers and AI-powered monitoring systems enhances patient outcomes and adherence.
• Government Initiatives for Healthcare Innovation: Japan’s government promotes the adoption of advanced healthcare technologies, including smart inhaler solutions.

Challenges

• High Costs of Advanced Devices: Smart inhalers and mesh nebulizers, though effective, may pose affordability challenges for some segments.
• Underutilization of Respiratory Inhalers: In many provinces of Japan, there is a strong inclination towards oral medication. In many prefectures in Japan, off-label drugs are prescribed for pediatric patients due to patient preference. This is due toa  lack of awareness, patient education and access to more technologically advanced respiratory inhaler devices.
