Production and quality control system

Connecting products based on established safe design with customer satisfaction

Makishinko actively pursues outside expertise and maintains a resilient production infrastructure responsive to the needs of this era.

Makishinko products are born from the knowledge, skill, experience and passion of each of the staff in our resilient production infrastructure in order to respond to the increasingly diverse and complex needs of this era. During this process, intensive communication occurs between our production site and business side staff through "standardization meetings" in order to achieve intensive progress in the business. Makishinko also proactively pursues knowledge from external partners through joint development, etc., in order to respond to the diverse and complex needs of this era.
