Originally, the Shimano Curado K was built in Japan. The Shimano K is made in Malaysia,  along with a number of Shimano reels. These days, and with the bigger brands, the question is less relevant, as quality control is usually pretty strict when reputations such as Shimano’s are at stake. The Curado comes with a 10-year warranty, which is a strong testament to Shimano’s faith in their manufacturing.
