Inside the Bell, a Small Life Has Taken Residence

In Hiroshima’s Peace Memorial Park stands the “Children of the Atomic Bomb Statue”—atop it is a golden crane held aloft by a three-pronged base, and above that is a bell. Inside that bell, which is supposed to ring with the wind, a sparrow has built a nest.

At first glance, this might seem like a mere quirk of nature. However, the city of Hiroshima decided not to remove the nest and chose instead to watch over the nesting process. The bell will not ring for a while. In its silence, another sound—the chirping of the chicks—can be heard from that place.

At the same time, 13 new names were added to the list of atomic bomb victims. Among them are high school students. Additionally, a survey conducted by the Hiroshima City Board of Education revealed that the percentage of children and students who correctly identified the date of the atomic bombing, “August 6,” exceeded 90%, the highest rate ever recorded.

These three events were reported in different contexts. Yet when viewed together, a certain structure emerges. Systems protect places, places attract people, and people pass memories on to the next generation—a nested mechanism that keeps “August 6” from fading into obscurity.

What the Silence of the Bell Protects

The Children of the Atomic Bomb Statue was established in 1958. It was created from donations by children across the country, inspired by the story of Sadako Sasaki, who was exposed to the bomb at the age of two and died of leukemia ten years later. Every year, around 10 million origami cranes are said to be sent to the statue. The statue itself functions as a “repository of children’s prayers.”

When the sparrow built a nest in the bell, the city had two options: to remove the nest and restore the bell’s function, or to leave the nest and temporarily stop the bell from ringing. The city chose the latter. This decision was based not only on the provisions of the Wildlife Protection and Management Law—which generally prohibits the removal of wild bird nests without permission—but also on deeper considerations.

What the “Children of the Atomic Bomb Statue” sought to protect was the life of a child. The decision not to evict the small life that had taken residence in the bell resonates with the statue’s founding purpose. The essence of this event lies in the fact that the system did not destroy the meaning of the place.

Writing Names, One Character at a Time

The list of atomic bomb victims is presented annually at the Peace Memorial Ceremony on August 6, a tradition that has been ongoing since 1952. As of 2024, the number of recorded victims exceeds 330,000. The list is written on washi paper using a brush, a task carried out by city officials and citizen volunteers.

In 2025, 13 new recorders were selected. According to reports, some of them are high school students. The recording process is not merely transcription. Each name is written out, character by character, with a brush on washi paper. The time spent moving one’s hand while reflecting on the lives behind those names is a physical experience that is entirely different from reading materials.

One recorder reportedly said, “I write each character with careful thought.” This statement suggests that the transmission of memory is not just about “the transfer of knowledge” but also about “the inheritance of actions.” There is a distance between knowing something and physically writing it down. The system of the list bridges that distance.

Every year, the names of 330,000 individuals are checked, newly reported victims are added, and deteriorating washi is rewritten onto new paper. This process is called “airing out.” The physical act of spreading the list to allow air to circulate prevents the paper from deteriorating, while the metaphor of allowing memory to breathe prevents it from decaying. The system maintains the place, the place requires human hands, and human hands leave memories as material—this is another nested structure.

The Design Behind the 90% Figure

In a survey conducted by the Hiroshima City Board of Education targeting children and students in the city, the correct answer rate to the question, “When was the atomic bomb dropped?” exceeded 90%. This is the highest figure recorded.

This number can be interpreted as indicating that “children’s awareness is high.” However, it is worth examining the structure behind it a bit more closely.

In Hiroshima’s elementary and junior high schools, a “peace education program” is systematically organized. Listening to testimonies from atomic bomb survivors, visiting the Peace Memorial Museum, and writing essays or giving presentations about peace—these activities are designed into the curriculum for each grade. Thus, the 90% figure is not solely the result of individual teachers’ enthusiasm or family educational policies but is also a product of a well-designed system.

At the same time, the average age of atomic bomb survivors has surpassed 85. As the number of direct witnesses decreases, systems for archiving testimony videos and the “transmitter” system—training citizens to learn from survivors’ experiences and share them—have been established. It is reasonable to view the 90% correct answer rate as a reflection of the accumulation of these systems.

However, the correct answer rate does not equate to depth of understanding. There remains a distance between being able to answer “August 6” and being able to imagine what happened on that day. To bridge that distance, experiences that engage the body, such as recording names and visiting the museum, are provided. The figures represent not a goal but the width of an entrance.

When the Three Layers Interlock

Let us organize the three events we have examined into a structure.

First Layer: System—The city makes the decision to protect the sparrow’s nest. Recorders for the list are selected each year, and the airing out process continues. The Board of Education designs the peace education program and verifies its effectiveness through surveys. These operate not through individual goodwill but as a system.

Second Layer: Place—The Children of the Atomic Bomb Statue, the Atomic Bomb Memorial, the Peace Memorial Museum. Physical locations function as “places to hold memory.” The bundle of washi paper that constitutes the list is also, in a broad sense, a “place.” Without the material that holds memory, the act of airing out cannot take place.

Third Layer: People—New recorders, high school students, children delivering origami cranes, and citizens speaking as transmitters. Memory begins to move when people enter the frameworks provided by the system and the place.

These three layers cannot function if any one of them is missing. Even if there is a system, if the place is neglected, people will not come. Even if there is a place, if the system is interrupted, it cannot be maintained. Even if there are people, without the system and the place, individual memories will remain just that. By nesting together and supporting one another, memory transforms from “individual recollections” into “social records.”

The sparrow’s nest, a coincidence, has made this structure visible. For the weeks that the bell does not ring, those standing in front of the statue will likely ask, “Why isn’t it ringing?” That question becomes an entry point for considering the relationship between system, place, and life. Coincidence is woven into the system, taking on new meaning—this is yet another manifestation of the nested structure.

Who Does This Make Comfortable?

The transmission of memory is often discussed with a sense of obligation, as something we must not forget. However, obligation alone cannot last for 80 years.

The reason the Hiroshima system has endured is that it has distributed the burden of obligation away from individuals and spread it across the system and the place. There is a curriculum in place that does not require one teacher to work tirelessly. Even if one survivor can no longer speak, the transmitter system remains. Even if recorders for the list change, the washi paper, brushes, and practices remain.

This system makes it easier for individuals to carry the weight of memory. By making it easier, more people can become involved. The inclusion of high school students in the recording process is made possible by lowering the barriers to participation.

As we approach the 80th anniversary of the bombing in 2025, the number of people with direct memories will continue to decrease. Therefore, the robustness of the nested structure of systems, places, and people will be called into question. The decision to protect the sparrow’s nest, the selection of high school students to take up the brush, and the 90% correct answer rate—each of these is a small fact. Yet within that smallness lies the design of 80 years.

The bell will ring again. After the sparrows have fledged, when the wind shakes the bell, the sound will carry a hint of the time that small life spent there. Memory thickens in this layered manner.
