Nakajima Ki-84, known as the Army Type 4 Fighter  to the IJAAS and the Frank to the Americans.

One of the best designs the Japanese Imperial Army Air Service put into active combat, the Ki-84 matched excellence maneuverability with a climb/dive capability unusual for Japanese fighters. More than a match for any American fighter, the Ki-84 also had the capability to intercept high flying B-29′s.

It’s only weaknesses were the wrecked infrastructure of the Japanese nation, leading to inconsistent production quality, poor fuel quality, and pilots rushed through training to get them into combat faster. 

Maj. Teruhiko Kobayashi started his career in the JAAF as a light bomber pilot over China. He rose to fame as a CO of the 244 Sentai defending the skies over Tokyo in 1944/45. Major Kobayashi is credited with five victories, three B-29’s and two F6F Hellcats. After the war, Kobayashi joined the Self-Defense air force and was killed in June 1957 in a training accident involving a T-33, crashing on approach in bad weather.
