Space exploration has always been associated with advanced materials, precision engineering and extraordinary technological complexity.  Satellites are typically constructed using aluminium alloys, specialised composites and other materials designed to survive the extreme conditions beyond Earth's atmosphere. Yet one Japanese research team has pursued an unexpectedly different approach: building a satellite using wood. In November 2024, Japan launched LignoSat, an experimental satellite incorporating magnolia wood into its structure. Developed by researchers at Kyoto University in collaboration with Sumitomo Forestry, the project set out to investigate whether a material used in construction for thousands of years could have a role in modern space technology. The satellite was not a wooden spacecraft in the traditional sense of the word. Its electronics, power systems and other essential components remained technological products of the modern space industry.  However, its woo...

When discussing the world's earliest civilisations, attention often focuses on Mesopotamia, Egypt, China or the Indus Valley.  Yet long before many famous kingdoms emerged, a remarkable culture flourished across the Japanese archipelago. Known as the Jōmon civilisation, this ancient society existed for thousands of years, leaving behind intricate pottery, sophisticated settlements and mysterious ritual objects that continue to intrigue archaeologists today.  Beginning around 14,000 BC and lasting until approximately 300 BC, the Jōmon period represents one of the longest continuous cultural traditions in human history. What makes the Jōmon especially fascinating is that they challenge traditional assumptions about civilisation itself. Despite lacking large cities, monumental architecture or agriculture on the scale seen elsewhere, they developed complex societies, rich spiritual traditions and artistic achievements that were far ahead of their time. Who Were the Jōmon People? T...

The 108 Earthly Desires (Bonnō): The Meaning Behind Buddhism's Most Famous Number Each New Year's Eve, the deep sound of temple bells echoes across Japan. At midnight, many Buddhist temples strike their bells 108 times in a ceremony known as Joya no Kane. Each strike is said to dispel one of the 108 earthly desires, or bonnō, allowing people to enter the New Year with a purified mind. Although the number 108 is widely recognised throughout East Asia, its meaning is often misunderstood.  Contrary to popular belief, Buddhism does not provide a universally accepted list of exactly 108 individual desires. Instead, the number represents a traditional classification of the many mental states that cloud human judgment and give rise to suffering. What Are Bonnō? The Japanese word bonnō (煩悩) translates various Buddhist terms, especially the Sanskrit kleśa, meaning "mental afflictions," "defilements," or "disturbing emotions." These are not simply desires in...

The Great Bell of Chion-in: Engineering, Faith, and the Sound of Seventeenth-Century Japan The Great Bell (Ōgane) of Chion-in Temple in Kyoto ranks among the largest functioning bronze temple bells in the world.  Cast in 1636 during the early Edo period, it weighs approximately 70 metric tons and continues to serve its original religious purpose nearly four centuries later.  Beyond its importance within Pure Land Buddhism, the bell represents a remarkable achievement in seventeenth-century metallurgy, civil engineering, and timber construction.  This article examines the historical circumstances surrounding its creation, the techniques employed in its casting and installation, and its enduring role in Japanese religious and cultural life. The Rise of Chion-in Chion-in Temple occupies a central place in Japanese Buddhism as the head temple of the Jōdo (Pure Land) sect, established by the teachings of the monk Hōnen (1133–1212).  Located at the foot of Kyoto's Higashiy...

Unit 731: the secret military unit of the Imperial Japanese Army that conducted some of the most horrific human experiments in modern history during the 1930s and World War II. ⚠️ This article is a grim reminder of human depravity: VIEWER DISCRETION ADVISED ⚠️ What it was Unit 731 was based primarily in Harbin, in Japanese-occupied China.  Officially, it was presented as a public health and water purification department, but in reality it was a covert biological and chemical warfare research program. It was led by Shirō Ishii, a military doctor who played a central role in developing Japan’s biological weapons program. What they did Unit 731 carried out brutal experiments on thousands of people—mostly Chinese civilians, but also Koreans, Russians, and some Allied prisoners of war. Victims were often referred to as “logs” to dehumanize them. Some of the atrocities included: • Vivisection (surgery on living people without anesthesia) • Deliberate infection with diseases like plague,...
