March 16, 1973

March 16, 1973, is the date associated with the graduation photograph of Yomiyama North Middle School Third-Year Class 3. Written on the back of a faded five-by-seven color photograph, the date identifies the occasion as the class’s graduation ceremony and fixes the image at the beginning of the historical chain that later becomes central to understanding the Yomiyama phenomenon.

The Date on the Photograph

March 16, 1973, appears in handwriting on the back of the photograph, above the note “All my friends in third-year Class 3.” The picture was one of four photographs preserved in the small box left behind by Ritsuko Sakakibara. Because the class appears to be gathered for a formal graduation photograph, the date is understood as the day of the ceremony.

The Class Photograph

The photograph shows the students assembled inside their classroom in front of the blackboard. The people in the first row are hunched slightly forward with their hands on their knees, those in the second row stand upright, and those in the third row stand on the teacher’s platform. The entire class is present in the frame, implying that a timer was used to take the picture rather than having one student remain behind the camera.

At the center of the second row stands the young Tatsuji Chibiki, then the class’s head teacher. His arms are folded across his chest, and his tightly pressed lips contrast with the smile visible in his eyes and cheeks. Ritsuko Sakakibara, fifteen years old at the time, stands diagonally behind him in the same uniform seen in the yearbook photograph later consulted in the Secondary Library. Her smile contains an almost imperceptible tension, giving the apparently ordinary graduation image an unease that becomes more significant as the hidden history of the class is reconstructed.

Misaki Yomiyama and the Erased Past

The photograph becomes important when Mei Misaki asks Koichi Sakakibara whether he can identify Misaki Yomiyama among the students. Her question directs attention away from the image as a simple keepsake and toward its status as evidence. The date places Misaki Yomiyama within the 1973 class photograph and connects the students’ remembered celebration with the later account of her death and the events that followed.

The photograph also stands against the later operation of the Yomiyama phenomenon. When the phenomenon is active, records, official documents, diaries, notes, photographs, videotapes, and computer data may be tampered with or corrupted so that contradictions caused by the presence of the “casualty” disappear. Memories are altered as well: even Tatsuji Chibiki, acting as an observer, had no suspicion that Mami Asakura was present in a class despite having died in October 1993. In that context, a surviving photograph dated March 16, 1973, is not merely an image of a past ceremony; it is a fragile material trace capable of challenging the false consistency imposed on the class’s history.

Historical Significance

The date gives the photograph a precise place in the chronology of Third-Year Class 3 and turns a private family relic into a key instrument of historical recovery. It preserves the arrangement of the students, the presence of the young Tatsuji Chibiki, and the appearance of Ritsuko Sakakibara while also prompting the search for Misaki Yomiyama. Its importance comes from the tension between what the image seems to show—a complete class gathered on a recognizable ceremonial day—and what the wider narrative reveals about concealed death, manipulated records, and collective forgetting.

March 16, 1973, therefore marks more than a graduation ceremony. It identifies the moment represented by an image through which the past becomes visible again, even though the Yomiyama phenomenon repeatedly works to make that past internally consistent, socially accepted, and difficult to question.
