The Third-Year Off-Campus Activity Policy

The Third-Year Off-Campus Activity Policy, also known as the No-Bus Policy or No-Field-Trip Policy, is a standing restriction at Yomiyama North Middle School created in response to the 1987 tragedy. Its decisive effect is to prevent third-year classes from undertaking group activities that require boarding buses and leaving the school, making an earlier disaster part of the school’s continuing organization of student life.

Origin in the 1987 tragedy

The policy arose after a bus carrying students from a third-year Class 3 left Yomiyama for the airport. On the highway at the edge of town, a truck whose driver had fallen asleep at the wheel crossed into the bus and struck it. The head teacher traveling with the class and six Class 3 students died, making seven victims from the class bus. A second bus behind it was also involved, causing additional deaths among people outside Class 3.

The scale and circumstances of the crash turned travel from a routine school activity into a recognized danger for third-years. When the history is explained, the change is presented as a direct institutional consequence rather than as a temporary response to grief: from the following year onward, the class trip was moved to the second year. The policy therefore preserves the memory of the accident through the school calendar itself, preventing the same age group from repeating the conditions associated with the loss.

Scope and operation

The restriction extends beyond the class trip. Since the tragedy, third-years as a unit have not been permitted to take field trips either. More broadly, they have no activities in which the students board buses and leave the school. The rule governs collective movement, not every form of individual travel, and its defining concern is the organized off-campus journey of the entire third-year group.

This arrangement gives the policy a practical and ritual dimension. A class reaches its final year with ordinary expectations of shared excursions removed, while the second year assumes the trip that would otherwise have belonged to the graduating students. The result is an annual reminder that Class 3 is treated as a special institutional case, even before the supernatural dangers associated with the Yomiyama phenomenon become explicit.

Relation to the wider Class 3 system

The policy belongs to a school culture that responds to danger through collective rules, restricted information, and controlled participation. The Secondary Library is described as safe for Mei Misaki and Koichi Sakakibara because Mr. Chibiki has no direct link to third-year Class 3; people without such a link can interact with them normally without affecting the class’s situation. By contrast, those inside the class are bound by rules whose effects depend on status and connection.

The same logic appears in the treatment of the so-called extra person or casualty. Records and memories may be tampered with while that person is hidden within the class, so details that should be impossible become acceptable and the class fails to recognize the casualty’s identity. The school’s off-campus restriction does not itself cause that phenomenon, but it demonstrates the broader institutional habit of converting past disasters into behavioral controls.

In 1998, the class’s attempt to increase the number of people treated as not there to two proved ineffective. After Mr. Kubodera’s death, the class gradually stopped ignoring Mei Misaki and Koichi Sakakibara, because there was no longer anything to gain from continuing that particular arrangement. The contrast is revealing: the off-campus policy is a durable response to a documented accident, whereas the class’s other countermeasures remain uncertain, improvised, and vulnerable to failure.

Enforcement, memory, and significance

The policy’s authority is reinforced by the school’s archival practices. Mr. Chibiki keeps copies of third-year Class 3 class lists covering twenty-seven years, from 1972 through 1998, with the newest lists filed on top. Such records place individual classes within a visible historical sequence, allowing past disasters and their institutional consequences to be compared across school years.

The rule also exists beside strict limits on how Class 3 members may be treated and addressed. Mr. Kubodera knew from the beginning that Koichi Sakakibara was related to Reiko Mikami, yet the class treated the relationship as a matter requiring formal separation at school. Reiko was addressed as Ms. Mikami in school and as Reiko at home, while Koichi was treated at school as Sakakibara, the transfer student. These practices show how Yomiyama North Middle School converts exceptional circumstances into everyday discipline: movement is restricted, identities are compartmentalized, and collective behavior is made to carry the weight of past deaths.

The Third-Year Off-Campus Activity Policy thus stands as one of the clearest examples of institutional memory in the story. It is concrete, comprehensible, and publicly defensible: seven people died in a bus accident, so later third-years do not travel by bus as a class. Yet its persistence also gives the school a haunted quality. A single catastrophe remains active decades later, not as a visible ghost or declared curse, but as a prohibition embedded in schedules, transport arrangements, and the boundaries of student activity.
