1909| Ginza Kurosawa Building     FRANCAIS
Everything best in office appliance
My motto is to sell the very best in office equipment. If not the best, I will not sell. I will only make money by selling the very best. (Motto by TK)
1909 Started to construct Ginza Kurosawa Building on October 18.
The first reinforced concrete office building in Japan.
Teijiro studied books on architecture and reinforced concrete buildings purchased from the U.S., and designed the office building himself. He was also involved in supervising the construction of the building.
Though designed by a layman who had never studied architecture professionally, the building was such that even professionals marveled at the quality.
(Asahi Newspaper dated April 5, 1980)
@Authorities on architecture like late Mr. Yoshio Taniguchi praised the Kurosawa Building as a polished and gracious building which blended with the cityscape beautifully. The building was pulled down last summer, but people who were involved in the demolition were amazed at the fine workmanship shown in every corner of the building. The technique used to connect steels, for example, is the technique used even today. Professor Omi who was studying the Kurosawa Building will prepare a report and give a presentation at one of the academic conferences.
The robustness of the Kurosawa Building is evidenced by the fact that it did not sustain damages when the Great Kanto Earthquake struck in 1923 or even with air-raids which struck Tokyo during the World War II. The reason for the robustness was countless railway rails found in the foundation and beams. From the marks on the rails, it was known that they were imported from The Providence Co. in Belgium and The Phenix Co. in Germany.
Steel frames used in the Kurosawa Building were supposedly steel rails originally used by the Tokyo Electric Railway System opened in April, 1905, connecting 0.8 km between Tsuchihashi and Toranomon in Tokyo.

The first period work was completed in December 28 1910, and the second in progress.

July 16 1912, the third period work is in process.
@ Though designed and constructed by a layman, the building was constructed painstakingly with care. gUtmost care was taken when blending the concrete. Even the gravel was panned and washed twice. I was reprimanded if I tried to cut corners. It was ridiculously laborious work. However, the completed concrete was beautiful. It was like polished stone and I was sorry to see it covered up with brick tiles.h

1912 The Ginza Kurosawa Building was completed in December. 7
Kurosawa Building
@ When working on a new technology, it does not matter if you are an expert in the field or a layman. The key for success is passion and ingenuity. Of course, it helps if you have a bit of technical sense as well.
The building was designed by Mr. Teijiro Kurosawa, a pioneer in the typewriter manufacturing technology in Japan. He was a born engineer but a complete layman in architecture. He set out to build the first reinforced concrete office building in Japan using a new technology, and he succeeded.
The building was completed in 1912, and for 70 years, it was part of a cityscape in Ginza. This distinguished looking brick-walled building with well-proportioned oblong windows has enjoyed high praise by all. It survived the great earthquake of Kanto and air-raids during the war. It proved that a building constructed with such attention and dedication would survive through hardships.
Using new technology without any examples to follow, Teijiro Kurosawa worked extra hard day and night. The building was a result of tireless and unrelenting hard work. He himself designed the building and he himself worked among laborers doing heavy lifting. While watching the building being taken down piece by piece, I saw evidence of ingenuity, dedication and efforts of the builder everywhere. The building showed us how a building should be built. Teijiro Kurosawa presented us a model to follow. I wonder how many of the fancy looking modern buildings are built with such care and attention. The building gave us a lesson. I wished that all those people who work on architecture and construction had a chance to see the Kurosawa Building. The building showed us how important it is to go back to basics. I now take a great comfort in knowing that a detailed record was made on the building during the demolition work and a new building has now been completed with remnant of the beautiful old building. I would like to say gCongratulationsh to the new building, and wish the best.
(Modern Japanese architecture and Kurosawa Building)
There was no doubt that the emergence of Japanese text typewriters has helped the advancement of telecommunications in Japan. In 1914, the Osaka Central Telegraph Office started to use an English typewriter to print incoming telegraphs.
The Osaka Central Telegraph Office then decided that typewriters should be used for Japanese telegraphs as well, and asked Mr. Teijiro Kurosawa, then the only importer and maintenance provider of typewriters in Japan and developer of the Japanese typewriter, to make a prototype Japanese typewriter suited for Japanese telegraphs usth typewriter as a platform.
( Remembering Teijiro Kurosawa by Seizo Ouchi)
1917 Using an L.C. Smith typewriter as a platform, the katakana typewriter for Japanese telegraphs was developed. It was named gWabun Smith (or Japanese text Smith)". 11

@ Characters were carefully assigned to each key on the keyboard after analyzing 1,838 telegraphs. Since then, Chinese characters on the keyboard were removed and we e widely used today. (History by TK) 14
@gTeijiro Kurosawa studied mechanical engineering in the U.S. and developed a Japanese typewriter after years of incessant hard work. His contribution and dedication in advancing business is to be highly commended. He is truly a role model for all Japanese people.h
To acknowledge Teijirofs distinguished services in the business world, the Japanese Government awarded tn Medalijiro on November 17, 1928.( Remembering Teijiro Kurosawa by Seizo Ouchi)
International Time Recording Co.
The relationship between Kurosawa and IBM first started at its time recording division. There is a description of a time recorder in the product catalog dated 1915. The wind-up type time recorder with a pendulum was priced at 445 yen.
Right after the Kurosawa Factory was completed in 1918, Kurosawa made the wooden case and fit it with imported clock movement and card recording parts. The time recorder was sold with a card holder to customers. Since then, the wind-up type was replaced by electric type, but the demand for the pendulum time recorder continued for some time. One of the very first time recorders is kept at Kurosawa Co. (Kuroswa Story)
1927 January 1, : Kurosawa became the exclusive sales agent in Asia for IBM. 17
@ International Tabulating Machine Co.
IBMfs history dates back before the development of computers. In early times, it was manufacturing Hollerith electric tabulating machine, punched card data processing equipment invented by Dr. Herman Hollerith. The equipment was used by the National Census Bureau and life insurance companies to process a large volume of data and by other companies for inventory management and cost accounting.
In Japan, the first tabulating machine was installed at Nihon Toki (Nihon Ceramics) by Morimura-Gumi in late 1925. At the time, Morimura-Gumi was a sales agent for IBM. However, Morimura-Gumi decided to give the exclusive sales agency license to Teijiro Kuroswa, who was a close friend of Baron Ichizaemon Morimura and who already had been doing business with the Time Recording Division of IBM. The exclusive sales agency license was put into effect on January 1, 1927.
Mr. Mizushina, who moved from Morimura-Gumi to Kurosawa led the sales force and sold aggressively. Mitsubishi Kobe Shipyard, Mitsubishi Nagasaki Shipyard, Kure Navy Factory and others purchased the equipment for cost accounting. Teikoku Life Insurance, Nihon Life Insurance and Takeda Chobei Pharmaceuticals also purchased to process statistical data
At around this time, military conflicts occurred in Manchuria and Shanghai, and the period of wars started in Japan. The business environment has become such that it has become difficult for Kurosawa to send business reports to the Corporate Headquarters of IBM. (Kuroswa Story)

1930 Started to make prototype Japanese telecommunications equipment. 20
1933 Succeededmanufacturing a katakana typewriter used for telecommunications. It was named gAZMATYPEh, (a machine to type A to Z manufactured in Azuma, nickname for Tokyo). 21

The same machine as the special-made "AZUMA TYPE" ordered by imperial house
@ There is one thing that I would like to tell you about Kurosawa-sanfs typewriters. The Emperor of Japan is noted for his study in biology. In 1931, Kurosawa-san developed a special typewriter to type small alphabets and katakana on small cards for the Emperor. The Emperor used this typewriter to keep the record ofrds. The same typewrithat was delivered to the Emperor is displayed at the Kurosawa Factory. ( Remembering Teijiro Kurosawa by Seizo Ouchi) 23
Teijiro Kurosawa invited Shuntaro Matsuo, Senior Engineer of the Ministry of Communications to the Kurosawa Factory and embarked on developing prototype telecommunications machine which could type Japanese texts. The Ministry of Communications established the Telecommunications Technical Study Committee in 1932. The Ministry asked communications manufacturers to complete and submit design sheets for the communications equipment in six months. Only two companies including Kurosawa submitted the design sheet within the due date. The Ministry of Communications then asked the two companies to complete the prototype in one year. It was only Kurosawa which made the due date.
In 1934, based on the experience of developing the prototype, Kurosawa started to work on developing the commercial machine. The Ministry of Communications sent two engineers to help with the woprototypes, the final specifications for the commercial model were completed in December of 1936.
(Kurosawa Story)
The Ministry of Communications had been taking the lead on the research of teleprinters made in the U.S. and Europe. In 1927, Teletype Company in the U.S. delivered a Japanese teleprinter, which was used for service between Tokyo and Osaka. The Ministry of Communications then decided on the policy of developing and manufacturing a Japanese teleprinter in Japan. In 1932, the Ministry of Communications issued a "request for design" to six manufacturers, including Oki Electric, NEC, Anritsu Electric and Kurosawa. At that point in time, Oki Electric lacked technology and skills to produce a prototype and it was only Kurosawa which complied with the request and delivered a prototype to the Ministry f Communications. It was only in 1937 that a Kurosawa Jaseleprinter became commercially available.
(Excerpt from the History of Oki Electric)

Teleprinter (using tape) manufactured in Japan by KUROSAWA (Communications Museum)
1937: On November 3, the very first gmade in Japanh teleprinter started operations between Tokyo and Osaka. It had been 10 years since the launch of the project.
The teleprinter was used by the Ministry of Communications and by newspaper companies as well. Because of this achievement, Teijiro Kurosawa received the Daimai Tounichi Communications Prize in 1940. (Kurosawa Story)
Debut of long-awaited Japanese Teleprinter. Communications Award was given to Mr. Teijiro Kurosawa. 28
Tokyo Daily Newspaper and Osaka Daily Newspaper Printing and Communications Awards are given for significant achievement in Printing and Communications, respectively. The Second Award Ceremony will be held at 11:00AM on May 1, 1940 at the Tokyo Daily Newpaper Head Office and the Communications Award will be given to Mr. Teijiro Kurosawa, who succed the Japanee teleprinterafter maips, and contributed in advancement of telecommunications technology in Japan.

@The first telegram by Kurosawa teleprinter receiver
We tested and inspected J-1 model Japanese in Japan, which had been delivered as test communications machine for the first time in 1936. We hereby certify is just as good as any other models made in the U.S. or Europe. ( Electrotechnical Lab) 31
This machine is often referred to as Teletype and used widely. If you type on this transmitting machine, each character is punched on the tape. On the receiving side, another machine will print on the paper. We completed this after more than a decade of hard work. (ROTARY WHEEL/T.K.) 32
