Large scale wooden buildings such as main halls of Buddhist temples or Shinto shrines are excellent object for estimation of the actual measure lengths, because their pillar distances reflect the modules or unit lengths. Fortunately, almost all important historical buildings were gathered in the book series of "Japanese important cultural asset (重要文化財)" published by Mainichi-newspaper in 1974-75, which appendix showed each floor plan and its main sizes. From these data, measure length were estimated statistically. The scale lengths in Japan were well known from the Nara period (Tenpyoshaku 天平尺 : 29.7 cm) to the Edo period (Kanejyaku 曲尺 : 30.3 cm with the most distributions), but it was not so clear whether the transition took place gradually or at the specific times. Therefore, first of all, the distributions of the estimated scale lengths are separately drawn from the Nara period to the Edo period. As judging from the results, the transition had happened clearly between the Nara period and the Heian period. In addition, the Kokanshaku (古韓尺 : 26.8 cm) was thought to be used in the Korean peninsula and the Japanese islands before the Nara period. The wooden buildings planed by the Kokanshaku were not remained so many but we were able to use similarly the floor plans restored from the archeological surveys. The results showed the Kokanshaku had been used subsequently to the Nara period.

In the era of Shogun Government the Japanese measures had the sizes strictly established and they were controlled by two shops which had the rights of monopolization of their manufacturing and sales, and inspection of those instruments in service, approved by the authorities. The two shops constituted a craft-union called \"Za\" those days. They put their head offices respectively in Edo, namely Tokyo nowadays and Kyoto, and controlled separately eastern half and western half of Japan, dividing it to two parts. At present we have some essays about dimension of these measures among which complete concensus of opinions is not found yet. This is the reason why I investigated old literatures and remains, and referred to the history of origination of the craft-union \"Za\". Editor's Note : The essay could not be completed due to the author's death in March, 1945. Moreover the magazine \"Keiryo Kai\, which inserted the essay, went out of print because of shortage of paper during the war time, so the latter half of what he wrote could not be brought into the world.

Introduction of the metric system in modern Japan was performed by Koan OGATA. His converted values from the traditional weights and measures into the metric system were taken over to the gunneries, Syuhan TAKASHIMA and one of his pupils, Motoyoshi NAMURA of the Takashima school. This school determined equivalents of numerical standards: the length "1m=3.28889 shaku (尺)," the measures "1l=5.48789 go (合)," and the weights "1kg=266.8144 sen (銭 or, monme (匁)) " respectively. However, Ryukei SUGITA's group had published "Kaijyohoujyutuzensho" from the astronomical charge of Edo Shogunate (called Tenmonkata) in 14th of Tenpou era (1843), which had translated Calten J.N. "Leiddraad bij het onderrigt in de Zee-artillerij" Delft, 1832, and was circulated setting a weights and measures standards to "1m=3.289248 shaku (尺)" and "1kg=266.8144 sen (銭)" . The former "1m=3.289248 shaku (尺)" was calculated from "1 latitude = 28.2 li (里)" adopted by Tadataka INOU. Takashima school would like to adopt the weights and measures standard of "Kaijyuohoujyutuzensho", after Syuhan TKASHIMA were restrained by Edo Shogunate in 13th of Tenpou era (1842). Shigetake TAKASHIMA who became Syuhan TAKASHIMA 2nd determined standard of the long length which was made "1m=3.289248 shaku (尺)" by INOU and its short length(called Kanejaku) which was made "1 m=3.3024 shaku (尺)", the later was shorter than the long length 0.4%. Short length was used for manufacture of actual commerce and industry products. Furthermore, he determined that weights performed "1kg=266.67 sen (銭)" therefore "1 sen(銭) = 3.75 g", as would be the result of "1l = 5.55 go (合)". Those weights and measures standard by him was taken over to Kinzaburo SHIMOZONE who was the last army magistrate in Edo Shogunate, and became foundation for the standard of modernistic weights and measures, especially length "1m=3.3 shaku (尺)" was so in Japan after Meiji Restoration (1868).

The analysis of pillar spans of Japanese national treasure buildings identifies several scale units other than well-known one of around 30cm, including longer range of 19-20cm, longer range of 24-25cm and longer range of 26-27cm. All of those are found in Nara era (eighth century) buildings. The values of 1.2 and √<2> are discovered to have been used in designing of ancient buildings as a multiplier and/or divisor.

A historical review of the achievements of the CIPM (Comite International des Poids et Mesures) during the period of 1989 to 2001, when the author was in the Committee, is presented. After introducing the framework and the structure of the Metre Convention, recent changes of the activity and the role of the CIPM and its Consultative Committees are explained together with their backgroud. The movement towards the establishment of the global traceability of measurement standards, especially the agreement for Mutual Recognition Arrangement of Metrological Standards and of Calibration and Measurement Certificates, is looked back in detail, referring to the cooperation of the CIPM with other International Organizations including the regional metrology organizations. The past and present management (the structure, budget, personel etc.) of the BIPM (Bureau International des poids et Mesures) is presented. In the end, the role of Japan in the activity of the Metre Convention for the development of the metrological standards and its global traceability in future is suggested.

Among cloth rules in Japan, a carpenter's rule was the regular one and later cloth rules called a "Gofukujaku" and a "Kujirajaku" of 1shaku 2sun 5bu long, both being adopted in a private use, were brought into the world around the Muromachi era. the Kujirajaku spread from the Kansai Province to the vicinities of the Kantoh Province and was used as a cloth rule until it was abolished at the end of 1958 by the Measurement Law. This article is the report of my investigation on the cloth rule which Family Takakura used in the Edo era by means of its historical materials for the ultimate purpose to clarify the period and provinces in which the Kujimajaku was in use. Family Takakura was one of the former aristcratic families, in charge of making clothes which Family of Emperor or Family of Shohgun had on the ceremonies or of dressing them in the court. Family Takakura has kept a gereat many of records till now in order to hand down the family work to the posterity without failure. The memorandum for dimmensions called "Sunpoh Todomegaki", gives us the record about the kinds of rules in use, which enables us to know the transition of rules. A good look at the above Memorandum according to the period allows us to understand the process how colth rules had been gradually unified to the Kujirajaku through the period when three kinds of rules, early carpenter's rules, Gofukujaku and Kujirajaku, were used together. Judging from addresses of dressers of the clothes and rules to be used, Family Takakura seems to have adopted Kujirajaku at earlier time. Even if the Family unified rules for clothes to Kujirajaku, accessories of the clothes had to be made by craftsmen except the Family, who used to normally adopt carpenter's rules. Exceptionally the string attached to the clothes were sometimes measured with Kujirajaku. still I tried to compare dimmensions of the memorandum "Sunpoh Todomegaki" with those of an older material, but failed in knowing when Kujirajaku was used at first.

In this report, a history of limit gauge system in Japan is chiefly investigated from 1930 to 1945. In Japan, the limit gauge system has been applied in machine shop since 1914. Nevertheless, this method had not fixed completely in many machine shops till 1945. When workers assembled the parts into a complete machine, parts were fitted by using jointly hand finishing. After the second World War, the limit gauge system has fixed in machine shops. In this background, it may be that special procurements of the United States armed forces compelled to use of limit gauge. In addition to, experience with mass production of machines in the second World War may also exist.

Amano Kiyosi (1907-1945), who was an able physicist and a distinguished historian of science but killed by the air raid 4 months before the termination of the W.W.II, performed extensive researches, both bibliographical and experimental, on the Japanese weights and measures of historical importance. Summarized in this paper are the achievements as well as the legacy of his researches, particularly on l) the relation between the old Japanese and the modern Metric units of length, 2) the variety of the local standards of volume in the feudalistic era of Japan and 3) the actual mass of the traditional weights preserved by several museums in Japan.
