“Naikan” 内観 is a self-reflective form of meditation founded by Yoshimoto Ishin 吉本伊信 (1916–1988), who developed it from a lay Shin Buddhist practice called mishirabe身調べ. After Yoshimoto used it to help prisoners in the 1950s, psychiatrists in the 1960s started to use it as a psychotherapy. Today in Japan it is the most popular psychotherapeutic method that originated in Buddhism. Naikan involves self-reflection on three questions: What have I received from a significant other? What have I given back to that person? What troubles and difficulties did I cause that person? People doing Naikan ask themselves these questions in relation to a family member or some other person during particular times in their lives. There are two types of the practice: intensive Naikan (shūchū naikan集中内観) and daily Naikan (nichijō naikan日常内観 or bunsan naikan分散内観). The former is done continually for a week at a Naikan training center, of which there are about twenty-five in Japan and several outside Japan in Austria, Germany, and the United States. During intensive Naikan, those doing Naikan report individually eight or so times a day their answers to the three questions to an “interviewer” (mensetsusha面接者). Daily Naikan is done as part of a person’s everyday normal routine for as short as a few minutes or as long as two hours a day. Intensive or daily Naikan is offered as a therapy at about twenty medical institutions in Japan and another fifteen in China. Intensive Naikan is commonly done for one of four reasons. First, it is done to solve a specific problem, such as alcoholism, gambling addiction, a psychosomatic disorder, or a bad relationship with a family member. Second, it is used to train employees so they can interact better with customers and colleagues. The Toyoko Inn, for example, which has over 230 hotels throughout Japan, requires all its full-time employees to do intensive Naikan. Third, it cultivates greater self-awareness with regard to, for example, how our minds work. Finally, it is done to discover the true nature of our lives through a spiritual awakening, which commonly entails the realization of how we live due to the care of others and how we suffer because of our own self-centeredness. This final purpose is in accordance with Yoshimoto’s view of Naikan as a method for learning how to live happily regardless of one’s life circumstances. Those who do Naikan for non-psychotherapeutic purposes sometimes use the term “Naikanhō” 内観法 (Naikan method) to distinguish their aims from Naikan therapy (Naikan ryōhō) 内観療法, which is used to solve a particular problem. But regardless of whether Naikan is done for self-developmental, spiritual, or for therapeutic reasons, the Naikan method of reflecting on the three Naikan questions is the same.
The Sōka Gakkai is a lay Buddhist movement, originating in Japan, that bases its religious practice and worldview on the Lotus Sutra-centric teachings of the Kamakura-era priest Nichiren (1222–1282). Following Nichiren, members of the Sōka Gakkai consider the practice of reciting Namu-myōhō-renge-kyō—the Daimoku, or title of the Lotus Sutra—to a copy of a character mandala (Gohonzon) originally inscribed by Nichiren to be the fundamental means for attainment of enlightenment. Also modeling themselves on Nichiren, the membership takes an active interest in the social and political realities of this world. In Japan, this engagement has taken various forms, including electoral support for a political party made up largely of Sōka Gakkai members, and globally, as activities in the fields of nuclear disarmament, sustainable development, human rights education, and humanitarian assistance. Founded in 1930, the organization was suppressed during World War II. In the postwar era, its rapid growth, driven by a campaign of aggressive proselytization, as well its ongoing involvement in politics, has generated considerable controversy within Japanese society. Even as the organization has matured institutionally, and in its relations with other faith traditions, an exclusive commitment by members to a single faith practice makes it an outlier within the Japanese religious landscape. The Sōka Gakkai in Japan currently claims some 8.27 million member families, making it the nation’s largest and most active religious movement. Outside Japan, under the rubric of Sōka Gakkai International (SGI), official statistics give membership totals of 1.75 million in 192 countries and territories, with 94 organizations incorporated under local national laws. More than half of the membership outside Japan—slightly more than 1 million—are said to be in Asia and Oceania, with South Korea, Taiwan, Hong Kong, and Singapore among the sites of large and active memberships. Other countries with significant national movements include Brazil, the United States, India, and Italy. While the Sōka Gakkai was originally associated with the Nichiren Shōshū sect, long-standing tensions over the respective roles of priesthood and laity came to a head in a decisive schism in 1991, since which the two groups have pursued independent paths. Following the schism, the Sōka Gakkai has given more central emphasis to the “mentor-disciple relationship,” in particular as this relates to the first three presidents of the organization: Makiguchi Tsunesaburō (1871–1944), Toda Jōsei (1900–1958) and Ikeda Daisaku (1928–).
