Accidents at Fireworks Displays: Don't Leave Safety Management to On-Site Workers
On Aug. 4, a fire broke out on two launch barges floating on the ocean during a fireworks display in Yokohama. The fireworks to be launched exploded one after another, causing five workers on the barges to jump into the water.
In Awaji, Hyogo Prefecture, on Aug. 3, a large firework exploded inside its launch tube. Fragments from the tube scattered, and it could have triggered other fireworks to explode.
No spectators were injured in either incident, but the accidents caused the events to be canceled. It is necessary to quickly investigate the causes of these accidents and take measures to prevent such incidents from reoccurring.
Fireworks displays that had been canceled due to the COVID-19 pandemic have resumed in various locations. Following the resumption, there were 50 fireworks accidents last year and 62 the year before. The most common type of accident at fireworks displays is fire burning undergrowth and other plants.
At a fireworks display held in Itabashi Ward, Tokyo, two years ago, sparks from 'shikake hanabi' fireworks that were fixed to a structure spread to the undergrowth along a riverbank, burning an area of about 2,000 square meters.
Fireworks companies are often commissioned by organizers, such as local governments, to put on a display. Due to the pandemic, there was a hiatus in the holding of such events, and it seems that some of the technical and safety management know-how was not passed on.
In recent years, there has been a trend toward elaborate but risky performances, such as launching large fireworks in rapid succession over a short period of time. Organizers are urged to strengthen their safety measures through such steps as not relying solely on contractors and instead confirming on-site safety equipment and fire prevention measures.
On-site safety management is not only an issue for fireworks displays.
On Aug. 2, four workers carrying out sewer pipe inspections in Gyoda, Saitama Prefecture, fell into a manhole and died. The four may have inhaled hydrogen sulfide, but they reportedly were not wearing safety harnesses to prevent falls or masks to prevent oxygen depletion.
This indicates that basic work procedures were not followed. Police are investigating whether there were any safety management issues at the company, which was contracted by the city to conduct the inspections.
The Land, Infrastructure, Transport and Tourism Ministry has urged local governments nationwide to ensure that contractors strictly adhere to safety measures during sewer pipe inspections. Local governments should also share information on safety measures and work together to establish such measures.
Work sites are facing severe labor shortages. With the retirement of experienced veteran workers, training younger workers has become a challenge. It is important to thoroughly investigate whether these factors have contributed to the occurrence of accidents.

80 Years On: Overseas Memorial Services for Japanese Families to End
News from Japan Society Aug 13, 2025 16:52 (JST) Tokyo, Aug. 13 (Jiji Press)--A program that allows families of Japanese nationals who died in overseas battlefields during World War II to visit memorial sites and hold commemorative ceremonies abroad will end this fiscal year due to the aging of participants. With this year marking the 80th anniversary of the end of the war, Nippon Izokukai, a bereaved families organization for the war dead and the program's organizer, decided that it would be difficult to maintain the initiative with the average age of participants exceeding 80. The program was launched in fiscal 1991 with the help of state subsidies. Many people have participated in memorial services to remember the war dead and in interactions with local residents in the Pacific islands, China, the Philippines and other locations that were once fierce battlegrounds. As of April 1, 2025, some 16,000 people had taken part in about 450 trips through the program. The number of participants has been declining recently, however, with many bereaved families growing older. After the number of participants peaked at 911 in fiscal 2005, the figure dwindled to 248 in fiscal 2023 following a brief program suspension due to the COVID-19 pandemic.

Accidents at Fireworks Displays: Don't Leave Safety Management to On-Site Workers
Accidents involving fireworks, which light up the night sky, have been occurring one after another and are a reminder that even these spectacular displays can be dangerous. Organizers and fireworks operators must take every possible measure to ensure safety. On Aug. 4, a fire broke out on two launch barges floating on the ocean during a fireworks display in Yokohama.

Resonating sound chambers built on Kii rice terrace
"Onkai," a cluster of resonating concrete chambers by German sound sculptor Lukas Kuhne, sits on a former rice terrace in Totsukawamura village, Nara Prefecture. (Toshiyuki Hayashi) TOTSUKAWAMURA, Nara Prefecture—This sounds unusual: 10 cylindrical chambers have been built on a former rice terrace in the depths of the Kii Peninsula. Arranged in a circle, the interconnected concrete tubes are a sound sculpture that found a home in the Taketo community of Totsukawamura village after a long search. The work is named "Onkai," the Japanese expression for a musical scale. 'Our community has been enlivened by hosting 'Onkai,'' said community leader Takuo Tamaki. 'We are going to do what we can to get the monument to be experienced by as many people as possible.' "Onkai" is the work of German sound sculptor Lukas Kuhne. Its cylinders are of different diameters and heights. The smallest is larger than the size of a public phone booth. The largest is a soaring 5.4 meters high. This makes them resonate at different frequencies. Wind blowing past the entrance causes the chamber to hum. But added to that are the resonances of other sounds--the whisper of trees, the patter of rain and the chirping of birds--all of which are heard differently by a person listening inside. Kuhne is a serial sound artist. He has built works in Estonia, Finland and Iceland. His Japan project got rolling after he spoke to Japanese enthusiasts at an arts festival overseas. The person who put him in touch with a prospective host community was Shin Nakagawa, a professor of ethnomusicology at Osaka Metropolitan University. Nakagawa knows Totsukawamura well. He has researched the village's Bon festival dance for the past 45 years. Kuhne asked to be put in touch, whereupon Nakagawa identified a community within the village that might be suitable. The project appeared to get a green light when local leaders wrote a letter of agreement. But it ran into opposition from some residents and from environmental activists from outside the community. They were concerned about the impacts of both building a concrete structure near a renowned scenic spot and having streams of visitors coming to see it. 'Not in my backyard' was their answer. But three years later, a solution was found. Takuo Tamaki, the leader of the tiny Taketo neighborhood, saw an opportunity for his neighbors. 'I thought that hosting the artwork might bring visitors to our declining community,' he said. Taketo is home to only 12 households with 18 residents in total. Tamaki said their average age is over 70. In 2020, the next hurdle was passed: the purchase of the land from a private owner with donations made to an association based in Taketo. Then it suffered another setback when the COVID-19 pandemic struck. Construction finally began in 2024 and was completed within the year. It involved collaboration between a local construction company and a crew of 10 engineers from an Estonian company that specializes in concrete architecture. The Estonian company picked up a large part of the 20 million yen ($135,000) cost of construction, including the costs for materials and transportation. What do visitors think? Mizuki Endo, a curator of contemporary art who has been involved in Kuhne's project from the start, said "Onkai" can be interpreted in many ways. 'It can be taken as architecture, sculpture, musical instrument or public art,' he said. '(It is) something you cannot categorize in one way or another, and opposition to it, in a sense, was understandable.' Nakagawa said the future of "Onkai" will depend on how it is used and received. He thinks it is valuable for three reasons: the engineering perspective of architectural technique; its esthetic value based on its appearance; and its social value in terms of generating a positive impact on locals and their neighborhood. 'Right now, its social value is zero,' he said. 'But it will go up if it is used as a venue for gatherings and events so that people can interact with each other.' The inauguration in June involved several events, including local drummers, ancient traditional dance, professional dancers and sound artists. And that was what Tamaki hoped for. 'This is the first time for us to see a crowd as large as this in the past 40 to 50 years,' he said.
