日本「えっ竹？もう使ってないけど…」 中国「竹の使い勝手良すぎワロタ」
While many in Japan now feel bamboo is largely a thing of the past, in China, it's undergoing a massive re-evaluation as an incredibly versatile material.
This fascinating gap in perception – Japan's "bamboo? we don't really use it" contrasted with China's "bamboo is ridiculously useful!" for everything from architecture to daily goods due to its eco-friendliness – is sparking online discussion.
The cultural and technological divergence in their approaches to bamboo is proving to be a surprising and engaging topic.

The Evolution of Bamboo Culture in Japan
From the Jomon period, bamboo has been integral to Japanese life, its flexibility and strength utilized in countless tools. From traditional arts like tea ceremony and flower arrangement to bamboo fences, crafts, martial arts equipment, building materials, fishing gear, and edible bamboo shoots, bamboo was deeply rooted in Japanese daily life. However, with significant societal and lifestyle changes after the period of high economic growth, inexpensive, mass-produced plastic and metal products became dominant. Bamboo products, requiring significant effort for maintenance and processing, gradually disappeared from everyday use. Especially after the 1970s, the decline of the entire domestic forestry industry, exacerbated by cheap timber imports and the spread of chemical fibers, led to abandoned bamboo groves. This neglect resulted in "bamboo blight" (bamboo inhibiting the growth of other trees and reducing biodiversity), landscape degradation, and an increase in wildlife damage. Today, while bamboo persists in some traditional crafts and tourist decorations, its former ubiquitous presence is lost, and the perception of "we don't use it anymore" is widespread. This also implicitly raises concerns about the potential loss of Japanese technology and culture.
Modern Bamboo Material Technology in China
China, as the world's largest bamboo resource country, has a long history of utilizing bamboo for bamboo slips (ancient books), flutes, and building materials. However, recent bamboo utilization in China has far exceeded traditional boundaries, achieving astonishing technological innovation. Particularly since the 2000s, rising environmental awareness and government policy support have accelerated efforts to redevelop bamboo as a modern, high-performance material. For example, "engineered bamboo" (bamboo laminate lumber), created by laminating and bonding thin bamboo strips, is used as a construction material with greater strength and durability than wood, widely employed in structural components for high-rise buildings, bridges, flooring, and furniture. "Bamboo fiber," with its antibacterial, moisture-absorbing, and breathable properties, is applied in textile products (clothing, towels), medical supplies, and hygiene products. "Bamboo pulp" is gaining attention as a raw material for paper and packaging, and as a plastic-free alternative, with bamboo straws becoming popular worldwide as a replacement for plastic straws. Furthermore, its applications are diverse, extending to automotive interiors, aircraft parts, musical instruments, bicycles, and smartphone cases. China's bamboo technology is not merely a substitute material; it maximizes bamboo's inherent properties and creates new value, embodying "green innovation" and holding astonishing potential, leading to the impression of "ridiculously versatile, LOL!"
Bamboo as a Sustainable Material
As achieving a sustainable society becomes a global challenge, bamboo is attracting significant attention due to its excellent properties. Bamboo's greatest advantage lies in its astonishing growth rate and regenerative capacity. While typical trees take decades to over a century to grow, bamboo matures in just 3-5 years, and new shoots continuously emerge from the culms even after harvesting. This makes it an exceptionally sustainable resource. Furthermore, bamboo absorbs large amounts of carbon dioxide during its growth, contributing to global warming countermeasures. It also has high soil conservation effects, aiding in the greening of degraded land. In recent years, with intensifying marine plastic pollution and climate change issues, bamboo has gained prominence as an alternative to plastic products, with bamboo tableware, cutlery, straws, toothbrushes, and packaging rapidly gaining popularity. These products are expected to reduce single-use plastic consumption and lower environmental impact. Moreover, bamboo often requires fewer chemicals in processing and is biodegradable, meaning it returns to the soil at the end of its life cycle, further reducing its overall environmental footprint. As efforts toward achieving international Sustainable Development Goals (SDGs) accelerate, bamboo's importance is growing as an eco-friendly option, driven by changing consumer and corporate awareness. The perception in Japan that bamboo is "no longer used" compared to China's assessment of it as "ridiculously versatile" can be understood against the backdrop of this international environmental consciousness and demand for sustainability.
