The main cause of the rise in this market segment is the increase in respiratory diseases, particularly asthma and COPD. The smoking epidemic as well as the rise in air pollution, and the overlap between asthma and COPD that makes the diagnosis complex are the significant drivers of this market. Together with the innovation of pulmonary disease drugs, the strategic partnership that the pharmaceutical companies are taking to the research and development level is driving its 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 while 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 in respect of improving the respiratory health of the Japanese people are the drivers in the Japanese market.

Advances in inhaler technology are backed up with the help of health professionals through changing treatment protocols by 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 participation of smart technologies in inhalers, for instance, adherence tracking and digital reminders it helps geriatric patients sticking to their routines and also it is associated to market growth in Japan.
• Target Market on Geriatric Healthcare: The high proportion of elderly population in Japan acts as a catalyst for inhalers specifically made for older adults, which include custom reminders, adherence tracking which, in turn, helps with prioritizing the ease of usage and precise drug delivery. Therefore, their use has increased and are used widely across the country.
• Innovations for Mother Nature: The manufacturers are reducing greenhouse emissions through the introduction of regulatory reforms that increase the pressure on cutting emissions. This has stimulated the manufacturers to develop regulatory guidelines and the adoption of inhalers that are shifting the market from pMDIs to Dry Powder Inhalers (DPIs) due to manufacturers. They are looking for the new inhalers which are reducing the 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 move towards home-based healthcare and long-term care.
