Yeah, Guadalcanal was a serious mistake that basically gave the americans the chance to fight a ground and naval battle in terms that weren't the best for either side but still better than having those same battles in other locations. I can only imagine the nightmare scenario of a counterattack of the scale of the Battle of Savo Island during the first night of the 2nd Marine division assault on Tarawa when the Marines were barely holding their positions and were a strong banzai charge away from being thrown to the sea. Without naval artillery and reinforcements during the next day who knows how many of the leathernecks would have survived?
actually the IJN wouldn't be able to do much. Remember that the USN pre war plan was for something like 15 fleet carriers, the full battleline, and all the pre-war cruisers and destroyers plus all the Cleveland/Baltimore/ fletcher swarm we'd built to that point.None other than Raizo Tanaka regarded Guadalcanal as a waste to defend, and argued strongly to pull the Japanese defense line back to anchor at Rabual. He was also openly critical of gradually feeding in reinforcements, fighting the decisive naval battles around the island, and how the logistics were handled, His outspoken criticism was why he was blamed for the failure of the campaign and put on the beach in Burma at the start of 1943, never to hold major command at sea again during the war.
Yes, Tarawa would have been far more difficult without naval gunfire and air support. What would have happened if IJN submarines were given a no limit hunting license on the invasion fleet? I mean, I-175 got in and nailed an escort carrier, then slipped away unharmed. What would have happened if a group of them went after the warships and transports? As it was, the Marines were in a world of hurt, when the low tide left them more than a half mile from the beach, because the Higgens boats couldn't get them over the exposed reefs. The Japanese forces were well dug in, and even the naval air and gunfire support available didn't do enough to suppress the opposition they faced on the beach.
The issue Guadalcanal created fir the IJN was that they gutted the entire South Pacific front trying to retake the island. After February 43 the allies had complete control of the airspace over New Guinea, and because of surface loses (for example half the IJN Heavy cruisers were sunk or heavily damaged by mid November) the 8th fleet was little more than an oversized desron. Its largely the reason (along with the lessons the allies learned from watchtower) that Cartwheel was as much of a cake walk as it was.
