Horyu-ji and Tokyo Skytree


In 1985 the Japanese Patent Office celebrated the 100th anniversary of the industrial property system in Japan.

On this occasion, they selected the 10 greatest inventions by Japanese.
The ten inventors are: 
Sakichi Toyoda 
  Patent Number 1195, Wooden Weaving Machine Driven by Human Power 
Kokichi Mikimoto 
  Patent Number 2670, Cultured pearl 
Jokichi Takamine 
  Patent Number 4785, Adrenaline 
Kikunae Ikeda 
  Patent Number 14805, Sodium Glutamate 
Umetaro Suzuki 
  Patent Number 20785, Vitamin B1 
Kyota Sugimoto 
  Patent Number 27877, Japanese typewriter 
Kotaro Honda 
  Patent Number 32234, KS Steel 
Hidetsugu Yagi 
  Patent Number 69115, Yagi Antenna 
Yasujiro Niwa 
  Patent Number 84722, Phototelegraphic Method 
Tokushichi Mishima 
  Patent Number 96371, MKM steel

But the greatest invention in Japan is undoubtedly Horyu-ji Temple, the world oldest existent wooden structure.  This Buddhist temple、31.5 meters tall, is thought to have been built in 607, though there were no reliable records about its foundation.  However, it is truly phenomenal that a wooden five-story pagoda survived 1400 years in Japan which has suffered an uncountable number of earthquakes and typhoons in these 1400 years.  So, many Japanese engineers and scientists have studied secrets of structure of Horyu-ji.

There are several unique features in the structure of Horyu-ji Temple.  But the most outstanding element is a huge vertical wooden pillar which is connected at the top layer of the pagoda to support the pinnacle but suspended without being fixed to other layers; it is placed only on a big stone in the ground.  This pillar runs through the center of the structure from the top roof to the underground about 6 meters below the ground surface.   However, today its underground part is rotten and lost, so that this pillar is actually dangling from the roof.

This pillar method is today applied to the Tokyo Skytree tower completed in 2012 as the world tallest self-standing tower (634 meters high).  This structure element fortifies the anti-earthquake property of Tokyo Skytree.  When the M9.0 earthquake occurred under the Pacific 400 km northeast of Tokyo in March 2011, the tower was almost completed and could well withstand the mighty earthquake.  No damage was found in Tokyo Skytree after big vibrations of the ground.

It is because the character frequency of the central pillar is different from natural frequencies of other structural elements around the pillar, movements of the pillar and other elements caused by an earthquake cancel each other out.   So, the tower can stand stable while receiving big energy of an earthquake.

The original structure of Horyu-ji had been first developed in China and Korea.  But both the countries have no such old wooden temples today.  The Horyu-ji type of wooden pagodas in other countries were all burnt or demolished through long history in those countries.  But only Japan could preserve it to date for 1400 years, partly because the capital of Japan was moved from Nara, where Horyu-ji was built, to Kyoto in 794.  Since then, Nara or Yamato Area, 500 km west of Tokyo, became less important politically.  Civil wars were not fought in Nara in later centuries.  It could at least avoid human-generated calamities.

Anyway, it will be difficult for any new inventions today to survive 1400 years.

So, the best thing in Japan is not necessarily in Tokyo.
