Prior to the 301st being formed as a full-fledged unit, it originally came into being as the Provisional F-4EJ squadron with only two aircraft in service on August 1, 1972.[4] It was the first unit of the JASDF to fly the F-4. On February 25, the first operational conversation course for F-4EJ pilots was started.
In April 1991, the squadron updated from F-4EJ to F-4EJ Kai aircraft.[5]
On October 31, 2016, as part of a JASDF reorganization it switched bases with the F-15J equipped 305th Tactical Fighter Squadron and returned to Hyakuri Air Base.[5] By 2016, the 301st TFS was tasked primarily with an air-to-ground mission, with its secondary role being air-to-air.[6]
One of the aircraft operated by the squadron (17-8440) was the last of the 5,195 F-4 Phantoms to be produced. It was manufactured by Mitsubishi Heavy Industries on May 21, 1981.[7] "The Final Phantom" originally served with the 306th Tactical Fighter Squadron.[4] In early December 2020, 17-8440 was withdrawn from use and flown to the Air Park Museum at Hamamatsu Air Base for preservation.[6]
On November 20, 2020, it was announced the 301st TFS had retired its Phantoms.[8] However, they continued to operate the Phantom up until December 10, finally being decommissioned on December 14.[9] On December 15, 2020, the 301st TFS completed relocation to Misawa Air Base and became operational with the Mitsubishi Heavy Industries F-35A Lightning II replacing their F-4EJs.[6] By March 2021, four F-35As (09-8719, 09-8721, 69-8701 and 89-8711) had been delivered to the 301st TFS.[10]

The squadron emblem of the 301st squadron is a frog wearing a scarf. The word for "frog" in Japanese is kaeru, the same sound (but different characters) as the word for "come home" (safely). The frog is based on the Japanese common toad, which is found by Mount Tsukuba nearby Hyakuri airbase where the squadron was formed. The frog wears a scarf adorned with stars. The number of stars represent the air wing it belongs to, and as it currently belongs to the 3rd Air Wing it has three stars. When it belonged to the 5th Air Wing at Nyutabaru in Miyazaki Prefecture from 1985 to 2016 it had five.[5]
The squadron appeared operating navalized aircraft in the Nuclear Aircraft Carrier Shinano 1990s novels by Shou Narumi (Mitsui Shinpei).
The squadron was also depicted in the 2012 Eureka Seven: AO manga. As the story took place in 2025, the squadron was depicted as having upgraded from F-4 to F-15J aircraft.
