Navy gymnastics.
He was known for the development of his own gymnastics based on the Denmark gymnastics. As a teacher of gymnastics at the Naval school, he had long felt a need that those in the navy should attain more alertness and flexibility of actions in the limited spaces of warships and he studied various methods; traditionally the Japanese Imperial Army had employed the Swedish gymnastics. Once, he had a chance of learning the Denmark gymnastics by visiting Danish gymnasts at Okayama, and developed his own system, based on the flexible movements of extremities; because
of his peculiar movements, he was nicknamed octopus man. He revealed the superiority of this gymnastics by showing the team he taught won high marks in various games and finally the Ministry of the Navy employed his method of gymnastics. In 1944, he was awarded for his development of gymnastics by the Navy Minister.

As an Administrator.
According to Japanese reports, Horiuchi treated the inhabitants of the island well, and was appreciated them. During his short tenure, he gave reportedly provided necessary goods such as salt, and reduced the tax to 1/4 of the previous amount. Horiuchi reportedly used the local language and according to one Japanese source, treated the prisoners of war (POWs) of the Netherlands fairly. On 11 January 1992, a goodwill meeting was held in commemoration of the 50th year of the parachute drop. Issai Horiuchi, the son of Horiuchi, carried the photograph of Horiuchi and several hundreds of the inhabitants attended the meeting. Hiroyuki Agawa, who later became a writer, was under Horiuchi when Horiuchi was transferred to Toukou of Taiwan in 1943 as a teacher of Naval students. Horiuchi said to Agawa that he was one of those who were loved by those in the occupied lands. He lost any desire or position when my assistant lieutenant died. To become a good commander, eliminate five desires, especially the sexual desire. Those who lost something will not kill others, but those whose lovers are taken by someone, may kill them. In the occupied lands, the Japanese army and navy made mistakes because of this.
As a B-class war criminal.
On 29 January 1948, a written indictment was read at the Manado Temporary Military Court which presented charges against Japanese Navy Colonel Toyoaki Horiuchi by the order of the Prosecutor General (dated 19 January 1948). The charges were that Horiuchi ordered or allowed Dutch army officers to be subjected to systemic terrorism. He was in a position of knowing the terrorism and did not punish Japanese officers. In 1942, at least 30 Dutch officers were killed with swords. He was in a position of knowing this but did not take necessary preventive measures. These are against the rules dealing with wartime criminals. Lawyer Ide stated that Horiuchi did not know these facts. There were 9 witnesses, most from the Dutch side. Horiuchi sent a letter of testimony that he did not know these facts. However, he felt responsible as an officer of superior rank. For a long time, he believed that we should love enemies. In January 1942, when he set up the parachute troop center, he strongly banned violence to those on the Dutch side. We treated these officers with respect and courtesy. He was impressed by Van den Berg officer who asked for permission while he was responsible. He punished his officers who gave him some violence. Based on his conviction, he freed 650 men of Indonesia. He admitted some of the violence had not been reported to him.
