Incorporation of the Society was first discussed in 1999, several years ago. In October 1999, the Steering Committee and the board of trustees at the 58th general meeting of the Japan Neurosurgical Society (Tokyo; the president, Takaaki Kirino) approved the establishment of a committee to discuss the advantages, disadvantages, and the need for incorporation as part of a strategy to reinforce the Society; consequently, the Japan Neurosurgical Society Discussion Committee on Incorporation (the chairperson, Akira Ogawa) started work. After discussions for a year, the 59th general meeting of the Japan Neurosurgical Society (Fukuoka; president, Masashi Fukui) decided to work toward incorporation to reinforce the Society regardless of some of the disadvantages. Simultaneously, the Discussion Committee was reorganized as the Japan Neurosurgical Society Preparation Committee of Incorporation of the Incorporated Association. The committee then started work in earnest.
The committee frequently consulted the Ministry of Education, Culture, Sports, Science and Technology, the main competent authority for the Society, submitting vast amounts of materials on the history and activities of the Society, including official journals of the Japan Neurosurgical Society (Neurologia medico-chirurgica [NMC]). As a result, the Society received approval from the Ministry as a fully qualified corporate body. At the same time, the 60th general meeting of the Japan Neurosurgical Society (Okayama; chairperson, Takashi Ohmoto) in October 2001 approved the basic organizational framework (draft) of the incorporated association. This basic policy served as the foundation for the current articles of incorporation based on the representative system. Subsequently, the Society submitted its charter, articles of incorporation (regulations of the society), organization regulations (draft), materials on the academic field, and a research and education system to the Ministry of Education, Culture, Sports, Science and Technology for discussion. During this period, the government reviewed the certification of public benefit corporations and delayed the response for incorporation.
In order to finalize the draft of the articles of incorporation, an administrative director for the initial phase of incorporation had to be named. In addition, to determine the representatives, necessary for convening a general meeting for incorporation, rapid improvement in the regulations for selection of the administrative director and the representatives were prepared for the initial phase of incorporation. At the 61st general meeting of the Japan Neurosurgical Society (Matsumoto; chairperson, Shigeaki Kobayashi) in October 2002, the new regulations were approved and preparations moved steadily forward. In April 2003, an informal decision was made to appoint Masato Iizuka, corporate secretary of the Graduate School of Engineering, University of Tokyo, as the secretary general for functional reinforcement of the office. This appointment was a positive influence on negotiations with the Ministry of Education, Culture, Sports, Science and Technology.
In June 2003, an election was held to determine representatives to the Representative Committee, the highest decision-making body of a corporation. After such deliberate preparations, the Society finally received a notice from the Ministry of Education, Culture, Sports, Science and Technology of its approval of the organization on September 25. The dissolution of the Private Organization, the Japan Neurosurgical Society, was approved at the 62nd general meeting of the Japan Neurosurgical Society (Sendai; chairperson, Takashi Yoshimoto). Subsequently, the representatives convened the organizational meeting of the Incorporated Association, the Japan Neurosurgical Society, on October 1, 2003. After the meeting, the final adjustment was made with the Ministry of Education, Culture, Sports, Science and Technology. On November 21, an application for approval of the establishment of the Incorporated Association, the Japan Neurosurgical Society, was submitted to the Ministry of Education, Culture, Sports, Science and Technology. On November 25, a review committee for incorporation was held. After a strict review, the incorporation was approved, based on which the final decision by the Minister of Education, Culture, Sports, Science and Technology was completed for the permit for incorporation on November 28, and the date of issuance of the permit was December 4. After the review for incorporation, progress was exceptionally fast.
Immediately after the issuance of the permit on December 4, the registration for incorporation was submitted to the Legal Affairs Bureau. Thus, the Incorporated Association, the Japan Neurosurgical Society, was officially established on December 4, 2003. Subsequently, on December 15, 2003, a notice of the completion of incorporation was submitted to the Ministry of Education, Culture, Sports, Science and Technology along with a duplicate copy of the incorporation register from the Legal Affairs Bureau verifying that all of the procedures for incorporation were complete.
