This paper introduces a mathematical puzzle book, Gobanjo, rediscovered on 2008. The radiocarbon dating on this book suggests that this puzzle book had been written on 15th century, which could be the oldest mathematical book in Japan. The Gobanjo shows us 6 types of puzzle utilizing go stones. The author summaries and translates these 6 types of puzzle into modern Japanese, i.e. Hyakugogenzan (Chinese Remainder Theorem), Shihoseki (counting the sides of square), Tonitarazu (addition and subtraction), Sassadate (simultaneous equations), Metsukeishi (guessing a hidden go stone), and Jugodate (3×3 magic square). Hitherto, as we had some knowledge about these puzzles except Metsukeishi, the author presumes the reconstruction of Metsukeishi utilizing the transposed matrix.

TAKEDA Shingen(武田信玄; 1521~73)was a renowned daimy(feudal lord) who governed Kai(甲斐) and Shinano(信濃)Provinces. As well as a military tactician, he was a man of letters. Shingen studied tanka poetry(和歌)because he aspired to hold both the pen and the sword(文武二道). His poem calligraphed on colored paper(色紙)is treasured in the Erin-ji Temple(恵林寺)even now. The poem reads as follows: sasowa-zu wa 誘引ずは kuyashikara-mashi くやしからまし sakura-bana さくら花 sane-kon koro wa 実こんころは yuki no furu tera 雪のふるてらIt is noteworthy that Shingen employed Chinese characters 誘引 and 実 in writingさそふ (to invite) and さね(really)respectively. By so doing, Shingen hinted at allusions to Wakan rei-sh (和漢朗詠集), Genji monogatari (源氏物語), and Ise monogatari (伊勢物語). This paper argues that Shingens tanka poem can be interpreted as a self-praise of his being a master of both the pen and the sword.

The aim of this article is to present the frame of reference of sociological history on the class culture and the education of the upper middle class in pre-war Japan. In modern societies, feudal statuses are substituted for meritocratic positions by new privileged class, that is, public servants, professions or the managerial class. These positions are acquired by licenses or education but not by one's social origin. Generally speaking, upper middle class city people know the importance of the educational background and give their children higher education which is acquired through their class culture. In this way, their meritocratic positions are inherited to their sons or daughters by hidden cultural capital.

Kitaro Nishida (1870-1945), a philosopher, served as a teacher at Yamaguchi-Kotogakko, a college under the old system, from 1897 to 1899. In this article, I will explore how Nishida lived and what he contemplated during his stay in Yamaguchi. In the first section, I explain about the school where he worked and discuss where he lived. Then, I will inquire into his diaries, letters and articles, in the second, third and fourth sections respectively. Reading his diaries during his stay in Yamaguchi, you gain a strong impression of his will, which he used to focus his consciousness as part of his Zen training to live an ascetic life. He also enjoyed climbing mountains, seeing waterfalls and playing a kind of football. His daily experience in nature and his practice of contemplation provided a context for his ideas about experience and the knowledge of reality. In the sixteenth century, Francis Xavier visited Yamaguchi. He spent more time propagating Christianity in Yamaguchi than anywhere else he visited in Japan. In the Meiji Era, Amatus Villion, a missionary, searched for the place where Xavier lived and found it in 1893. According to Nishida’s letter to his friend, while he was in Yamaguchi he was deeply impressed by the words, “Which of you by taking thought can add one cubit unto his stature?” which is written in the sixth chapter of The Gospel according to Matthew. This helped him get rid of his dissatisfaction and complaints and feel easy and peaceful. Yasunosuke Yamamoto published an article in 1898 called “Religion and Reason”. According to it, every religion has it’s own >creed<, which is identified with a dogma. Men who believe the creed have >beliefs<. The emotions that drive us to seek spiritual peace hinder the development of reason in a religion and so men accept a creed blindly and irrationally. Yamamoto expressed a view that we should not be restrained by our >emotions< and should develop our >reason< in our religion. Nishida objected to Yamamoto’s view of religion. In the same year, he published an article, “My comment on Mr. Yamamoto’s article titled ‘Religion and Reason.’ ” He says, “It is not true that a creed precedes a belief, but it is true that a belief precedes a creed.” We can escape from the limited world, go into the unlimited world, unify with the Absolute and experience “the reason why the reality of the active universe as a whole is what we see.” Nishida called this kind of >intuitive understanding< a >belief<, which is most important for him. The >belief< is originally beyond words but becomes expressed as a >creed< with concepts and words, which is not so important for him. His view of religion attaches greater importance to the intuitive and emotional understanding than to the only intellectual knowledge and understanding. Nishida found in the center of religion a desire to escape from the limited world and unify with the Unlimited. He regarded God not as transcendent out of the cosmos but as working immanently in the midst of the cosmos. Such a view of religion during Nishida’s stay in Yamaguchi was expressed also in Study on the Good (Zen no Kenkyu) which was published in 1911. 哲学者、西田幾多郎(1870~1945年)は、明治30(1897)年から明治32(1899)年まで、旧制の山口高等学校の教師を務めた。本稿は、山口時代の西田がいかに生き、いかに思索していたのかについて考察する。第一章では、西田の職場である「山口高等学校」とはどのような学校なのかを述べ、そして、西田が山口のどこに住んでいたのかについての情報を整理する。そのあと、彼の日記・書簡・著作に順次目を向ける(第二・三・四章)。 山口滞在中の彼の日記には、禅の修行、そして自分の生活を禁欲的に律することへと意識を集中しようという決意がみなぎっている。その一方で、山に登ることや滝を見ることやサッカーをすることを楽しんでいる。そのような日常の経験が彼の思索の背景にある。 山口は、16世紀にフランシスコ・ザビエルが日本で最も長い期間滞在し布教した土地であり、1893年、ヴィリオン神父の尽力によって、ザビエルの住居の場所が発見された。西田が友人に宛てた書簡によれば、彼は山口で「マタイによる福音書」第六章の「あなたたちのうちの誰が、思い煩ったからといって、自分の背丈を一尺ほどでも伸ばせるであろうか」という言葉に感動し、それによって、いろいろな不満が解消し、心が安らかになったという。 ところで、山本安之助は「宗教と理性」という論文を1898年に発表した。それによれば、いずれの宗教にも「信条」(教理)があり、信者はこれを信仰する「信念」をもっている。安心を求める感情が、宗教において理性が働くことを阻害し、人々は盲目的・非合理的に信条をうけいれる。山本は、宗教において、「感情」に束縛されずに「理性」を働かせなければならないという「啓蒙」的な主張を表明している。 この山本の宗教論について西田は反発し、同じ年、「山本安之助君の『宗教と理性』と云ふ論文を読みて所感を述ぶ」と題する論文を発表する。西田は「信条ありて而して後信念あるにあらず、信念ありて而して後信条あるなり」と言う。つまり、彼にとって何より大事なのは、有限界を脱して無限界に超越して絶対的なるものと一体化し、「宇宙実在が全体として活動する所以のもの」を「感得」することとしての「信念」であった。「信念」が概念化され言葉となった「信条」はそれほど重要ではない。宗教において、このような「感得」や「感情」を重視する一方で、「智識」や「理解力」は重視されない。 有限世界を脱して無限なる力に合一することを宗教の中心に置き、神はこの宇宙の外に超越しているのではなく、この宇宙のただなかで働いていると考える西田の山口時代の宗教観は、1911年に発表される『善の研究』でも継承されることになる。

This article aims to help tanka-making beginners learn rhetorical expressions from tanka poems by KASHIWAZAKI Gyoji (1941-2016) and HONGO Sumie (1934-). The two poets learned the art of tanka from one of the major contemporary tanka poets: MIYA Shuji (1912-1986). The fact implies that the two poets learned from Miya some skills of making tanka. The characteristics of rhetorical expressions by the two poets are summarized as follows. The tanka poems by Kashiwazaki generally use plain expressions: they are mostly composed of plain vocabulary both in kango words, words made of Chinese characters and read in Chinese way, and wago words, original Japanese words. For example "地面" (jimen or ground) and "ちかづく" (chikazuku or coming nearer). Kashiwazaki avoids expressions not used in daily lives such as a compressed or shortened expression; for example 落ち実 (ochimi) or fallen fruit. Instead, he uses a natural phrase of 落ちた実 (ochita mi). Contrastively, Hongo makes use of strongly sounding kango such as 精魂 (seikon), meaning a steadfast will to realize something. She might have learned the use of this type of kango from Miya. Hongo also uses utakotoba, a word dominantly used in tanka, not in everyday life, such as kirigishi or a sharply cut cliff, and compressed or shortened expressions such as 熟実 (uremi) or ripe fruit. ("Uremi", when heard, is difficult to understand, and should be "ureta mi" in daily communication.) The article suggests that shortened expressions by Hongo come from those by Miya. Learning the rhetorical expressions by the two poets, tanka beginners are expected to pursue useful rhetorical expressions for the tanka they would like to create.

Mishima Yukio’s Silk and Enlightenment (Kinu to Meisatsu, 1964) is a long and a ratherunfortunate novel in that it received uncertain reviews of both approvals and disapprovals by thecritics. Where did Mishima’s true intention lie in writing this full-length novel?Fuefukigawa Art Library, where Mr. Hatano Takeo acts as the President, holds many of thebooks owned by Mishima himself. I was so fortunate to be given the opportunity to examine thefour books that provided sources for Silk and Enlightenment. Indeed, I was the first scholar to begiven access to these items, which are all concerned with the industrial actions that took place inthe rapidly growing silk factory, Omi Kenshi.In these four books, many underlines are drawn and marginalias scribbled in by Mishimahimself. Also, whenever he found useful accounts for his novel, he folded the top corner of pages.In fact, there are applications of such relevant parts in Silk and Enlightenment. The pages,stained with Mishima’s greasy hands, have now turned into almost black over forty years and hisfinger prints are clearly retained in some of them. By tracing the pages he referred to, we caninvestigate minutely into the process through which the novelist constructed the plot, created thecharacters, and rendered the novel as close as possible to the real historical incident.Silk and Enlightenment compares the two contrasting spheres: the enlightened world ofthe West, which is represented by Heidegger and Hlderlin, and the chaotic reality of Japan asexposed through the industrial actions over the silk factory. Mishima’s own thought on Japanduring the industrialising period is made clearer by the above four books discovered in his library.It also elucidates his researches on the subject of the hitherto uncertain relationships between theworld of West and that of Japan. Mishima had an eye for the uniqueness of Japanese society as wellas an eye to observe the cultural universality.Besides, this research becomes the key to understanding the root of Mishima’s ‘motivationsas a novelist’ which drove him in the first place to select out these four reference items on theindustrial actions at Omi Kenshi. It sheds a new light upon his fundamental views on humanity andthe world.I am confident that this paper will present a model case for future studies on Mishima Yukioby making a close and detailed analysis of Silk and Enlightenment (Kinu to Meisatsu), for thefirst time, by actually basing research on Mishima’s marginalias on his own books.

This article aims to demonstrate three significances of tanka poems by HONGO Sumie (1934~), who has lived for sixty years in Nishijin, Kyoto: the significance of her poems in depicting the glory and decline of Nishijin fabric industry and the ever-inspiring historic places of and figures in Kyoto; the beauty and artistry of her poems in exploiting a variety of rhetorical expressions; the possibility of making ordinary Japanese people realize the beauty and richness of the Japanese language. Among her conspicuous rhetorical expressions is the use of onomatopoeia like saya-saya, light and rhythmic sounds of a bamboo or a small waterfall, describing a Nishijin fabric machine and a small waterfall in a well-known garden in Kyoto. Another is the frequent use of hikari or light, referring to encouraging aspects of the world around her. In a tanka poem her late husband is associated with light (hikari) and a shield (tate). Not well-known to the tanka-related people, the poet deserves, the author believes, to be accepted as a distinguished Nishijin- and Kyoto- related poet. (Kyoto and Nishijin need a poet who gives literary description of its glorious culture and history.) Her use of uta-kotoba or words frequently used in tanka poems like modasu or ‘to remain silent’ might enable ordinary Japanese people to be impressed with not-daily-used beautiful Japanese expressions, thereby being more interested in their native language.

In this article, we examine whether bad news on a company impacts on the correlations betweenthe equity return of the company and those of other companies based on the Japanese equity datain 1997, when some of major financial institutions bankrupted. We define "contagion" or "exclusion" as a significant increase or decrease, respectively, in the correlation after the announcement of thebad news. Our major findings are (1) whether the effect of the bad news is "contagion" or "exclusion" basically depends upon the nature of the bad news, (2) heteroskedasticity in thecorrelation has some influence on the identification of the bad news effect and it is important toadjust the heteroskedasticity in the correlation to correctly identify the effect.

Apocryphas are, in biblical literature, works outside accepted canon of the scripture. They arrived in medieval Russia through Slavonic translation of Byzantine literature. The author in this bulletin provides the translations and the commentary of following five medieval slavonic apocryphas. Their outlines are as follows:(1) A Story of Akir the wise: Akir, an able minister and counsellor of Assyrian Empire, had been plotted by his nephew and sentenced to death by his king. However, a friend of Akir gave him shelter in his own house. In absence of Akir an Egyptian pharaoh gave hard problems to the Assyrian king and threatened to send troops if Assyrians could not solve them. The Akir's friend confessed to their king that Akir was alive and Akir, who was then forgiven, solved the pharaoh's problems. Akir took revenge on his nephew. The minister Akir was mentioned in "the Book of Tobit" of the Old Testament.(2) An Eriphery's Story of twelve Fridays: Friday is a special day for Christians because Jesus Christ was crucified on Friday. This story explains why and how in a calendar twelve special Fridays should be venerated.(3) A Story of Melchizedek: Melchizedek, "a king of justice" in Hebrew, is an enigmatic character in Holy Scripture. This story describes how Melchizedek was born and hidden in the background of Holy Scripture.(4) An Aphroditian's Story: The episode of the arrival of three magi is popular theme of the New Testament. This story is based on that episode of the Holy Scripture, and describes how in the East, that is, in Persia three wise men came to be sent to Bethlehem to celebrate the birth of Jesus Christ. (5) A Story on the King Abgal: Abgal, a king of Edessa in Osroena kingdom, was suffering from leprosy, and wished Jesus Christ to come to Edessa to realize a miracle. Jesus, instead of himself coming, sent him a towel, with which Jesus wiped his face and in which the shape of his face was left. This was believed in the Christian world to be the first icon of the Savior. This story is the incarnation of the idea on icons "acheiropoietos = made not by human hands".
