About Our Logo
The mass of flags, suggesting a troop stronghold, represents the solidarity and the support in times of adversity that TSK draws on to take on the world from its base in Japan. As each employee hoists the same flag, employees feel pride in their work and are inspired to continue the challenge. The logo also connotes our employees’ determination to protect this stronghold (the Company).
The flag’s pattern represents the experience and trust earned from years of tube production, as well as TSK’s technical capability and high precision in production of various sizes and surface processing.
