Take the following as truth: In 1854 Perry duly negotiated the Treaty of Kanagawa (now part of Yokohama), opening up two ports, Shimoda on the Izu Peninsula and Hakodate in Hokkaido.
Then the following statement: "A treaty opening up ports in Shimoda and Hakodate was negotiated in 1854." is true, false, or inconclusive?
Answer: True
