Prior to the establishment of the day school, Japanese children in Guam attended a special supplementary Japanese school.[5] The Guam Japanese Association began considering making one in March 1972 and it opened by May 1973. It occupied the conference room of the Japan Airlines office at Guam Airport, then St. John's School beginning in September 1975, then to the Fujita Hotel beginning in September 1979, then six classrooms in Tamuning Elementary School beginning in July 1987.[6]
Around the years 1987-1989 there was a committee held to establish a Japanese day school in Guam, with the decision to formally create a Japanese school being made in April 1988.[7][8] The day school opened in April 1989 as the Agana Japanese School (アガナ日本人学校 Agana Nihonjin Gakkō). Originally its campus was the Pacific Islands Club (PIC) Hotel in Tamuning, near Hagåtña (Agana), which now housed both day and weekend schools. In April 1990 the permanent campus in Mangilao opened.[6] The dedication occurred the previous March.[9] The building, with 10 classrooms, had a total cost of $2,000,000.[10]
The school received its current name on March 17, 1999 (Heisei 11).[6][11]
A kindergarten division was created in 2002, with 2 students enrolling that year.[8]

Turkey is not included in the classification of Europe by the Japanese Ministry of Education (MEXT). Nihonjin gakkō are day schools operated by Japanese associations and usually only include, within the Japanese system, primary and junior high school levels. Shiritsu zaigai kyōiku shisetsu are overseas branches of Japanese schools; these are boarding and day schools. MEXT categorizes Japanese sections of European international schools as hoshū jugyō kō part-time schools and not as full-time schools. See the template for part-time schools.
