The Japanese submarine I-1 was a J1 type submarine built by Kawasaki, Kobe, for the Imperial Japanese Navy. She was a large cruiser submarine displacing 2,135 tons and was the lead of four boats built in the class.
She was commissioned on 10 March 1926 and served in the Second World War. On 29 January 1943, during Operation Ke, the New Zealand naval trawlers Kiwi and Moa intercepted and wrecked her after a surface battle at Kamimbo Bay, Guadalcanal.
On 29 January 1943 she encountered the much smaller 607-ton New Zealand minesweepers, Kiwi and Moa. Unable to penetrate the I1's armour with their deck guns, the minesweepers rammed and chased her to shallow water, eventually forcing her to run aground on the reef at Kamimbo Bay, Guadalcanal. The wreck partially protrudes from the water. Coincidentally the Kiwi and Moa's only sister ship, HMNZS Tui sank the I-17 seven months later.
Critical codes remained on board and the Japanese command tried unsuccessfully to destroy the boat with air and submarine attacks. The US Navy reportedly salvaged code books, charts, manuals, the ship's log and other secret documents.
I-1's pennant is on display at the National Museum of the Pacific War in Fredericksburg, Texas.
