Teikoku Seiyaku is the world's number one producer of poultices.

By focusing on a specific business area, Teikoku Seiyaku aims to be the leader in that given area. To us, being an “essential provider” means being the leader in our field, no matter how narrow that field may be. To that end, Teikoku Seiyaku produces more than 18,000 tons of medicated plasters each year. This is equivalent to approximately 1.2 billion sheets measuring 10 by 14 centimeters each, or travelling 4.2 times around the Earth if the patches were laid together in a side-by-side landscape position.
