The only successful Ohka attacks were against US ships. For some reason, they attacked destroyers..not exactly high value targets. You'd think they would have gone after carriers.

On 12 April 1945, nine "Bettys" attacked the U.S. Fleet off Okinawa. The destroyer Mannert L. Abele was hit, broke in two, and sank, witnessed by LSMR-189 CO James M. Stewart. Jeffers destroyed an Ohka with AA fire 45 m (50 yd) from the ship, but the resulting explosion was still powerful enough to cause extensive damage, forcing Jeffers to withdraw. The destroyer Stanly was attacked by two Ohkas. One struck just above the waterline, with the charge punching completely through to the other side of the hull before splashing into the sea and detonating, causing little damage to the ship, and the other Ohka narrowly missed and crashed into the sea, knocking off the Stanly's ensign in the process.
May 1945 saw another series of attacks. On 4 May 1945, seven "Bettys" attacked the U.S. Fleet off Okinawa. One Ohka hit the bridge of a minesweeper, Shea, causing extensive damage and casualties. Gayety was also damaged by a near-miss by an Ohka. One "Betty" returned. On 11 May 1945, four "Bettys" attacked the U.S. Fleet off Okinawa. The destroyer Hugh W. Hadley was hit and suffered extensive damage and flooding.
From what I've always read, the Ohka was designed expressly as an anti-shipping weapon. Any air-to-air use would likely have been a last-ditch desperation tactic. As 330thbg says, they had very limited fuel and were extremely difficult to control in anything but a straight-in run at a relatively slow target. Hitting an aircraft in flight would be next to impossible, especially for pilots with only rudimentary training. The Japanese did have specialized ramming squadrons for use against B-29s..sometimes the pilot was able to bail out, but it was usually seen as a suicide attack. It certainly wouldn't surprise me to find that Ohkas were used as well.
I have a grudging respect for the Japanese suicide pilots. Many westerners like to dismiss them as fanatical Emperor-worshippers, but most were intelligent young men who didn't want to die, but simply saw self-sacrifice as the only way left to defend their country and people from an overwhelmingly powerful enemy how was pounding their country into oblivion. If the situation were reversed, I bet many American's would voluntarily make the same choice.

A very good book to read about the Kamikaze pilots is "THUNDER GODS" by Hatsuho Naito. Per the book, I don't recall any mention of use of the "Maru Dai" ,the code name for the Ohka, against aircraft, but it does mention building "body crash" weapons for air-to-air use. The Ohka was built to pierce armor,the main objective being stopping the U.S. Navy fleet and the invasion troops they carried. In one successful hit, an Ohka went completely through a ship and exploded in the water. Considering how few were built, it's hard to believe any were used air-to-air, BUT, you can't argue with what people have seen and commented on.
