In the end, the Imperial Japanese Army decided to withdraw from Guadalcanal because they were unable to provide effective material support (food, ammunition, and supplies) to the remaining troops on the island.

This was due to two major factors: the inability of the IJA to dislodge the Americans from around Henderson Field, thus allowing the Americans complete air superiority over the surround seas, and the strategic defeat of IJN forces in the Naval Battle of Guadalcanal and Battle of Santa Cruz. (both naval battles were tactical victories for Japan, but strategic ones for the US)

Unable to establish sea superiority in the naval battles, and unable to neutralize the American planes at Henderson Field, the IJA could not bring in critically needed heavy supplies to keep their soldiers combat-effective. With no supplies and few reinforcement to continue the fight, the IJA eventually withdrew from Guadalcanal.

What was the invasion of guadalcanal a counterattack for?

The Marine invasion of Guadalcanal had several facets, and was mainly a response to Japanese attacks toward Port Moresby in New Guinea. Guadalcanal in the Solomons was a valuable location for control of the surrounding waters. Strategically, Guadalcanal was the first major American response to Pearl Harbor (the first being the Doolittle bombing raid in April 1942), but on a tactical basis, it was essential to open a second front in order to protect Australia. If the Japanese were able to open their planned airfield (re-named Henderson Field after being captured by the Marines), they'd have been able to interdict American shipping sending supplies to Australia. Capturing and retaining control of Guadalcanal was essential to the American war effort, by keeping the southern thrusts of the Japanese forces in check.
