Core Viewpoint - Japan's regenerative medicine and related products are lagging behind the US and Europe in practical applications, with significant investments planned to enhance production capabilities by 2027 [1][2]. Group 1: Investment Plans - Nikon and four other Japanese companies plan to invest over 100 billion yen by 2027 to significantly increase production of iPS cell products and other advanced pharmaceuticals [1][2]. - Nikon will invest approximately 10 billion yen to expand its production base in Koto, Tokyo, increasing the cleanroom area by 50% and tripling its workforce by 2030 [2]. - AGC plans to invest 50 billion yen in its Yokohama facility to set up production equipment for regenerative medicine cells, with potential for mRNA vaccine production if necessary [2]. Group 2: Market Position and Challenges - The US has approved 25 drugs in the gene and CAR-T fields, Europe 22, while Japan has only 10, indicating a significant gap in production capabilities [1][2]. - Japan's domestic companies have a weak production foundation, which could hinder access to advanced medical treatments and reduce the competitiveness of the Japanese pharmaceutical industry [1][2]. Group 3: Government Support - The Japanese government will provide 38.3 billion yen in subsidies over four years to support equipment investment and talent development for CDMO in regenerative medicine [3]. - Emerging companies, such as SanBio and Cuorips, are seeking conditional production and sales licenses for their regenerative medicine products, indicating a growing interest in this sector [3]. Group 4: Market Growth Potential - The market for regenerative medicine products in Japan is projected to reach 53.8 billion yen by 2030, doubling from approximately 2024 levels [3].
