In February 1942 Minematsu served on the seaplane tender Kamikawa Maru flying the Mitsubishi F1M2 ‘Pete’ biplane scout.
In the middle of February Kamikawa Maru and Sagara Maru sent a detachment of F1M2s to the island of Banka to operate from Muntok.
On 16 February while flying from this detachment, Minematsu together with another pilot intercepted Dutch Glenn Martin of 3-VIG-III together with Ki27s of the 1st Sentai. The Dutch bombers were out to intercept Japanese shipping in the Moesi River on Sumatra. The F1M2s reported intercepting three or four twin-engined bomber over the shipping during the afternoon. Minematsu made six attacks, claiming one bomber probably shot down, but his own aircraft was hit many times and he was forced to alight on the sea, some 40 miles west of Muntok. The destroyer Hatsuyuki rescued him and his observer, the wrecked aircraft being set alight and sinking later. The other floatplane also made several attacks, but with no observed success. The Dutch bombers claimed three of the attackers shot down while one of the bombers didn’t return. This was Sergeant J. Bakker’s M-578 which failed to return.
Minematsu ended the war with 1 probable biplane victory.
