John Cabot, an Italian explorer sailing under an English flag, is best known for his voyages across the Atlantic Ocean in the late 15th century. On his first voyage in 1497, he is credited with reaching the coast of what is now Canada, specifically believed to be near Newfoundland. His second voyage in 1498 was less successful, and the exact locations he reached during that trip are not well-documented, but it is widely thought that he continued his exploration of North America.
Therefore, the answer is Canada.
