A unique aspect of Japanese housing is that dwellings are assumed to have a limited lifespan and are normally demolished and rebuilt after a few decades, usually twenty years for timber buildings and thirty years for concrete buildings—see rules for specifics. This is especially true in urban areas where construction standards often aren't high enough to support aging systems for longer than this. However, if you look around older cities like Tokyo, you'll see many timber homes from the early twentieth century still standing today.
In general, yes, Japanese houses are designed to last. They're typically constructed with quality materials and proven techniques, and as long as they aren't exposed to extreme weather conditions or damaged by vermin, they will serve their purpose over time.
Many factors go into the design of a house, including the type of wood used for construction and how it's put together. For example, wooden houses are often divided into several sections (called "rooms") that can be taken down and moved as needed. The strength of wood allows for this kind of flexibility while still providing protection from the elements.
Also important is the type of glue used to bind the wood together. In Japan, people often use tanegami, which is a paper product similar to newspaper but made solely from bamboo.
The first is that Japanese dwellings are only supposed to endure 30 years. The belief that Japanese houses self-destruct after three decades is a result of the government's goal to keep the economy humming with a steady need for residential building, since the 30-year time restriction was devised by the Land Ministry. If demand stagnates, then so will construction, which could have negative effects on the economy as a whole.
The second reason is that the country's housing market is very fragmented. There are lots of small independent house builders who may not have the financial resources to invest in new technology or materials. So they tend to use what's popular at the time and go for fast designs with cheap, easy to find ingredients such as wood, plaster, and concrete. These houses come with terms like "lifetime" or "forever" because there's no way to know if they'll last longer than 30 years.
The third reason is cost. In today's market, it can be difficult to find a house that isn't priced out of reach of most people. Even if you can find something affordable, how can you be sure that it won't disintegrate next year?
The fourth reason is location, location, location. In order to make an affordable house that doesn't fall down you need to put up with locations that aren't quite ideal.
While the West has numerous stone structures, Japanese houses are usually built of wood, therefore rebuilding and upgrading must be done once per generation as a general rule. While some Japanese houses are over 100 years old, the majority are estimated to have a lifetime of 30 to 50 years. There are several factors that contribute to the short lifespan of Japanese houses. Most commonly, wood is used because it's easy to find and affordable, but it will decay over time.
There are many types of wood used in Japanese buildings, including pine, bamboo, cypress, maple, and oak. All of these materials are subject to rot and insect damage, especially when they are used outside under the sun. The best protection against decay is actually heat - if you burn wood at a high temperature for a long time, it will disappear completely of its own weight after about 350 degrees Celsius. So avoid burning furniture! In fact, even when not burned, older woods tend to get lighter in color because they've already lost much of their original mass by then. Any wood that is still solid and hasn't decayed is suitable for building projects.
Outside housing, Japanese trees are often preserved because they provide useful products. Pine trees produce resin that can be used for waterproofing buildings, and bamboo grows very quickly and is widely used for construction. Inside the house, wood is usually kept out of sight because it is considered bad luck to have objects blocking your view.
Why are there so many empty houses? There are a variety of complex reasons why Japanese residences become unoccupied. The most apparent reasons are a dropping birthrate and an aging population, but geography is also a factor. Most Japanese cities are far from work, school, and other amenities, so people move away from their cramped urban apartments to more spacious suburbs or rural areas.
However, not everyone who leaves their house intends to never return. Some abandonments are temporary while others are permanent. Sometimes the owner moves out but can't be found, leaving the property behind as ransom against injury or crime. Other times, residents flee violence in the neighborhood by finding another place to live. Still others may leave because they were involved in some type of accident where they need time to recover before they can return home.
Often, when people abandon their homes, they take their belongings with them. This is called "kakure kosai"—a mysterious deserted house. Occasionally, these vacant dwellings are sold at auction or through real estate agents. If the house was part of a residential block, then someone else might move into it which would eliminate its appearance of solitude.
There are several terms used to describe people who go missing. They include hikikomori, omoshiroi, shirakami, and uchikomi.
Traditional Japanese homes are constructed by stacking wooden columns on top of a level base of packed dirt or stones. Wooden homes may be found all over the world. House walls used to be built of woven bamboo coated with dirt on both sides. Today, they are more commonly made of wood. The roof is usually thatched with grass or reed bundles.
Traditional Japanese houses have two main advantages over their modern counterparts: first, they are very energy efficient because they do not have aluminum or copper sheets for windows; second, they are very safe because there are no electric wires inside the house.
In Japan, there are three types of traditional houses: the yagura, which is a small tower attached to a house as defense against intruders; the donjon, which is a large fortress-like building where warriors would live and train; and the jihei, which is a simple one-story house with tiled roofs that can be found in villages everywhere in Japan.
There are some differences between how men build houses and how women build houses. Usually, the husband of the household will be the one to construct the house. But if he is not able to work due to illness or some other reason, then his wife will be responsible for building the house. Women use different kinds of materials than men do. They usually use wood, but sometimes they use bricks or tiles instead.
Why are Japanese buildings constructed of wood? – According to Quora. Brittle materials include bricks, stone, cement, and RCC. Because of its flexibility and elasticity, wood provides both strength and a cushioning effect. As a result, dwellings built of wood are more vulnerable to earthquakes. However, wood is much cheaper than other materials so it is still used for building houses.
What is so special about Japan? It's a pretty dry place full of volcanoes, but they mostly stay quiet. The reason is that Japan is made up of islands surrounded by water: ocean to the east, north, and west; Sea to the south. This means that there is very little land area, which makes it difficult to build large structures. In addition, most buildings in Japan are small, because large buildings use up too much space relative to their size. Smaller spaces mean less traffic, which is good for business.
Japanese architecture has evolved over time into different styles. The oldest part of Tokyo is made up of wooden buildings dating back around 700 years. But most cities today are made of concrete, because it's easier to work with than wood and can better withstand earthquake damage.
Despite having little land area, Japan has some huge buildings. Most famous is the Tokyo Tower, which was built in 1973. It's 442 feet tall and has become a popular tourist attraction. There are also several other skyscrapers in Tokyo too.
