This article examined enlargement construction of the Yoshizawa's main house in 1913 from the building and the building document both sides. It's the following points to become clear.
 The entrance hall part built in the front of the main house at the time in the middle of the Meiji era is connected. It was revealed that the main house body portion was enlarged in 1913 from the building document and the inscription of the ridge-end tile. The main house was modified from wood-roofing to tile-roofing in 1913. This is a precious example indicating the tile-roofing having spread here from this time.
 Eikichi Kaneyasu estimated the central room enlargement construction of 1913 at first in July, 1912. And Eikichi showed the estimate with changing it again in November, 1912, but the estimate to change of December was shown by Hamakichi Nishiwaki. Eikichi Kaneyasu cannot carry out construction and can I judge that Nishiwaki succeeds a contract of Eikichi and carried it out.
 By the enlargement construction of 1913, there were at least three times of estimates by changing it. A roof was changed from thatching the roof with shingles to the tile-roofing by the first change of November, 1912. The expansion of the scale and the second-floor plan were added by the second change of December, 1912. The third change of March, 1913 changed the eaves. As a result, the building area of the central room increased 3.7 times as much as the estimate at first.
 This enlargement is a precious example indicating the tile-roofing having spread here from this time. Moreover, the maker who supplied the tile to the enlargement construction of the main house was Shiono Takezo of Zingamine.

 Up to the previous draft, by comparing the price of Japanese nail in the estimate in “Kaiti-gakko” building in 1875 and the price of the Western nail from 1892 to 1911, I considered the conversion from the Japanese nail to the Western nail in terms of price. Specifically, by comparing the Japanese s and the Western nail, which have the same length, it was revealed that the price of the Western nail in 1911 had fallen to about 1/50 of the nail of 1875. Also, from 1892 to 1911, it also showed that the Western nail moved prices from 1/29 to 1/50 against the Japanese nail in 1875. By the way, although this paper showed the change in the price of the Western nail during this period, I could not show the change in price of the Western nail from 1877 to 1891 due to restrictions on the materials. Therefore, in this article, considering the relationship between the trend of the Western nail and the price of the Japanese nail in 1882 to 1891, etc., based on the business situation published in “Tyugai-bukka-sinppo etc. The following points were obvious.

 By examining the business conditions during this period, we can learn the price fluctuation of the Western nail and compare it with the price of the Japanese nail. In 1882, the Western nail became 1/21 of the price of the Japanese nail in 1875, 1/25 in 1891. The price of the Western nail in this period can be confirmed raising and lowering. However, looking at the price of the Western nail throughout the Meiji era, prices rose to some extent gradually and gradually changed from 1/20 to 1/50 with respect to the Japanese nail. Looking at the price of Western nail in units of one year, the price dropped in the summer and the price went up from autumn to winter. The reason was due to the production of buildings and wooden products since early spring. In addition, the change in the Western nail price over the several years was greatly affected by global syndication and purchase by nail businesses in Tokyo and Osaka.

The authors conducted an interactive Tanka appreciation activity with upper intermediate level learners and conducted a survey which examined the process and changes in the interpretation of Tanka. The result of the survey indicated that it was difficult for the learners to develop a concrete understanding of Tanka due to their lack of understanding in grammar. However, once the learners understood the grammar correctly, their interpretation changed. Therefore, the authors considered that it is important for teachers to create scaffolding which tailors to each learner’s comprehension level.

In “Kugi”, it was noted that there was the nail with multiple actual dimensions for one nominal length of Japanese nail. According to Honto (estimation date) in 1803, the actual size of “hira-kugi” was about 90% of the nominal length. In addition, the actual length of “kashiramaki-kugi rui” was about 80% of the nominal length. Furthermore, the actual length of “kenchiku-you-kugi” was about 30 to 40% of the nominal length. In fact, it is not clear whether such a nominal length was used in “kenchiku-you-kugi”. And it is not clear in the past how nails that actual dimensions were about 90% or 80% were used together with “kenchiku-you-kugi”. The purpose of this article is to clarify how the actual size of Japanese nails, which is different from the nominal length, was distributed and established. The following points are clarified.

The example of adding letters such as “dai” in front of the nominal length of the nail is from ancient times in “Kenchiku-daijiten”, but the actual example is from the end of the 16th century. In the distribution of nails from ancient times, the “ren-kugi” that could be seen from the Heian period to the early Edo period were not seen after the middle Edo period. Until the early Edo period, the “ren-kugi” was used for nails of less than 3 sun, but since the middle of the Edo period, the description by the nominal length has come to be seen even for nails of less than 3 sun. In early modern times in Japan, there were nails with a nominal length of 90%, 80%, and 30 to 40% of the actual length for one nominal length. As you can see, the price of nails is widely distributed, and some price ranges were shown. The nails, which account for 30 to 40% of the actual length, have the same size system as “ren-kugi” used until the early Edo period, and it is considered that the nominal length was addressed to them. As a result, one nominal length has a plurality of actual size nails coexisting, and the actual price has shown a wide range. In addition, even after the middle of the Edo period, the numeral “wa” used in “ren-kugi” was used in part in the distribution of nails. Although “ren-kugi” was also used for nails of more than 3 sun, there were also cases in which one bundle was uniformly set to 100, not based on the idea of “ren-kugi”.

From the above consideration, it became clear that it’s difficult to immediately know the actual dimensions of the nominal length nails described in the literature since the middle of the Edo period. This is because there were at least three types of real-length nails for one nominal length in this era. Therefore, in order to know the actual length with respect to the nominal length, it is necessary to make a comprehensive judgment in consideration of where the nail is used and the price at the same time. By the way, after the Meiji Restoration, Western nails flowed into Japan. Since Western nails were distributed by using the numerical value in which the dimension based on the actual dimension was replaced with shaku-sun, the relationship between the nominal length and the actual dimension in Japanese nails was also corrected.

 This article examined conversion from Japanese nail to Western nail in the Meiji Era from the viewpoint of price. The following points were clarified.
 From the building documents of the Kaiti-Gakko, the price of Japanese nails in 1875 became clear, and in the case of nami-4-sun Japanese nail, it was 0.30 yen in 100 pieces. The actual length of this nami-4-sun size can be judged to be 1.2-sun from the description of "Kugi".
 By "Umemoto-Syoho" in January 1910, the price of western nail at that time becomes clear. According to this article, it was 1.5 -inch western nail that corresponds to the real length 1.2-sun Japanese nail. And the price of this western nail 1.5-inch was about 1/50 of the Japanese nail of 1875 when it corrected the influence of price based on the Wholesale price coefficient. By comparing with the market price of "Umemoto-Syoho" in January 1910, it can be judged that the price of western nails in “Meijiki-Osaka-Orosiuri-Buttka-Siryo” (4) was indicated by 1-kin of Japan. Moreover, from this result, it was possible to overview the change in Western nail price from 1892 to 1911. During this time, western nails fluctuated at the price of about 1/29 to 1/50 against Japanese nails in 1875.
 The Nail Market of the "Tyugai-Bukka-Sinpo" dated September 20, 1889 is valuable as a source of “Meijiki-Osaka-Orosiuri-Buttka-Siryo”(4). According to this article, at that time the price of western nails was about 1/28 of the price of Japanese nails in 1875.
 By "Koukoku" of Sumiya. S, Seki-Honmati, Mino, February 15, 1894, we can know the price of western nail. This price was in compliance with “Meijiki-Osaka-Orosiuri-Buttka-Siryo”(4), but it was increased by 10%. In other words, the price of Sumiya was considered to include expenses as a dealer.
