Importance of Installations

Every building needs equipment.

To some extent, anything other than structure such as electricity, lighting, communication, air conditioning, plumbing, disaster prevention, hygiene, clean rooms, and kitchens are all equipment.

Such equipment is closely related to various uses from our daily life to the industrial society.

As evident in the development of household equipment, advanced medical devices in hospitals, and enlargement of public facilities, equipment has developed significantly since decades. Equipment technology has also contributed greatly to this evolution.

The TAKARA group specializes in plumbing, ventilation, and air conditioning systems.

We play the role of maintaining the indoor air quality for a comfortable living environment and the improvement of productivity at factories and other installations, while fulfilling our mission of the hygienic use of water indispensable for our lives.

Plumbing system

Water-related equipment, such as toilets, baths, washbasins, and kitchens etc., is indispensable to and has a close connection with the economic functional aspects of everyday life including houses and condominiums, as well as offices and commercial facilities. Systems such as drinking water, hot water supply and drainage are designed, arranged, and piped in buildings based on complicated calculations in buildings. This is an important system for us to maintain a comfortable, hygienic and safe environment.

Ventilation and air conditioning system

Airtightness and verticalization of buildings has been progressing in recent years. Therefore, the air ventilation system plays a very important role in parallel with the plumbing system in creating efficient and comfortable building space focusing on the level of comfort of the space as well as economic running costs without loss of energy for heating and cooling. Although the temperature, humidity, and cleanliness of the air are invisible, the air conditioning system is also designed and constructed with careful calculation and design.

History of facility installation

You may have heard people complaining about dirty bathrooms or stomach problems caused by drinking water in foreign countries.

Having clean tap water, and bathrooms so clean that people choose them as places to take a break, it is something we take for granted in today’s Japan, but it was not achieved overnight.

It was not until in the Edo period when the Tokugawa Shogunate was established that a waterworks system was constructed for the first time. The present-day Hibiya Park and the vicinity of the Imperial Garden used to be a shallow sea area, and the well water, which was the main water source at that time, contained salt. Edo was not a place blessed with water supply. Therefore, the Tokugawa Shogunate developed six systems for clean water for many generations, and as the systems in the Kanda River and the Tama River remained, they supported people’s lives until the Meiji era.

While the modernization of other fields rapidly advanced, these two waterworks systems continued to supply unpurified river water to the city through underground stone and wooden gutters to wells. In addition, there was also a time when water supply was poorly managed, due to factors such as the establishment of ship passages in the water purification channel and the failure to collect water rates caused by the transition of institutions controlling the water supply as a result of the unrest after the Meiji Restoration. In the meanwhile, cholera was brought by crew members of trading ships and the major outbreak of the disease resulted in the deaths of over 110,000 people throughout the country. A cholera epidemic broke out also on the coast of the Tama River, a water source, and there were numerous cases of patients with waterborne diseases caused by unclean drinking water such as dysentery and typhoid fever. This prompted the construction of Western-style modern water supply systems.

While facing budget difficulties and land acquisition problems as well as material and labor shortages due to the war, modern water supply systems were constructed in large cities such as Yokohama, Hakodate, Nagasaki, and Osaka as well as in places with trade bases. These modern water supply systems did not even reach 10% of the population until the end of the Meiji era, but the figure grew to about 30% by around 1940 and reached 97.5% in 2010. Today, Japan’s water supply system ranks first or second among major developed countries not only for its diffusion rate but also its good water quality and low water leakage rate.
