Football at the Inter High School Sports Festival[a] is an annual event at the tournament, popularly referred to as Inter-High (インターハイ).

However, in order to deal with the extreme heat, the men's competition will be held every year from 2024 onwards on Fukushima Prefecture.

In case of a draw on full-time, penalty shoot-outs will be required, with no extra-time being played.

The only exception is in the final, where a 20-minute extra time with 10-minute halves will take place, proceeded by penalty shoot-outs should the match remains tied.

16 schools qualifies for the tournament, with three from Kanto, two from Tohoku, Tokai, Kinki and Kyushu and one from Hokkaido, Hokushin'etsu, Chugoku, Shikoku and the year's host prefecture (its region wins an extra slot).
