I. Introduction
This study aims to focus on Yorozu no humihougu 万の文反古 (“An Old letter scrapbook”; 1696), a collection of posthumous works in the early modern Japanese genre of Ukiyozoushi 浮世草子, written by Saikaku Ihara 井原西鶴 (1642?–1693) as a classical, foundational document of Japanese culture; then it will examine the “authorship problem” in Saikaku’s works using the tools of quantitative analysis.

In contrast to so-called scholarly books with named authors, graphic novels or storybooks called soushi 草子(realistic literature), were generally anonymous in this era. The earliest work generally acknowledged as Ukiyozoushi 浮世草子, and thus the first Japanese early modern novel, emerges with the publication of Saikaku's Kousyoku ichidai otoko 好色一代男 (“The life of an amorous man”; 1682) (Munemasa 1969), but there are almost no attributed (signed) works among the 23 Ukiyozoushi 浮世草子 considered to be Saikaku’s. While work on Saikaku has proceeded, these fundamental doubts about his authorship remain.

Meanwhile, the potential of quantitative analysis of textual data and the related field of the digital humanities have also dramatically advanced. However, quantitative analysis of Japanese classical works has lagged behind. Delayed digitalization of classical works has been a problem due to complications regarding development of morphological analysis software for classical works. At this moment, adequate morphological analysis software for early modern Japanese literature does not yet exist.

Five Saikaku's collections of posthumous works were edited and published from 1693 to 1699 by followers of the author including Dansui Houjou 北条団水, on the basis of unpublished drafts considered by them to have been Saikaku’s. As a result, some doubt arose subsequently about the authorship and publication history of these works.

Yorozu no humihougu 万の文反古 was published as the fourth such collection of posthumous works, in the third year after the death of Saikaku (1696). This work is a collection of epistolary novels, consisting of 17 chapters each telling a different short story. The next section considers the doubts about Saikaku’s authorship.

II. Previous Studies
A. Doubts raised by Yamaguchi
Yamaguchi (1929) mentions that Yorozu no humihougu 万の文反古 may be an apocryphal work actually written by Dansui, for the following reasons.

1. While the handwriting is similar to Saikaku’s, the lines are bolder and there is a slight lack of roundness due to the powerful strokes.
2. Unlike in the other posthumous publications, Dansui did not provide a preface to Yorozu no humihougu 万の文反古.
3. The publishers of Yorozu no humihougu 万の文反古 are the same as those for Saikaku oridome 西鶴織留, the unfinished second collection. There is doubt as to why they chose to publish Yorozu no humihougu 万の文反古, later than Saikaku oridome 西鶴織留 although it was in more complete form.
4. While it seems clear that some of the work was written by Saikaku, some chapters seem to have been rewritten by Dansui to impose an epistolary form and remove some descriptive passages. It is considered that these intrusions are less elegantly composed.
B. Arguments for Saikaku's scholarship
Teruoka (1953) thinks that the handwriting is similar to Saikaku’s, but notes that even if this is not the case, it does not prove that Saikaku did not write the actual text, which he feels exhibits clear ideological commonalities with Saikaku’s other work. In addition, Taniwaki (1981) raises various doubts but ultimately assumes that all 17 chapters were written by Saikaku since the inventive ideas would have been beyond the range of his imitators.

C. New doubts raised by Nakamura
Nakamura (1982) mentions Yamaguchi’s concerns regarding the handwriting, concluding that the handwriting likely belongs to the author of Tanba Taro monogatari 丹波太郎物語 (“The story of Tanba Taro”), not Saikaku.

On the basis of similar arguments, Nakamura actually makes an argument for the identities of the authors of each chapter.

The existence/non-existence of the later insertions to the book has not yet been settled. For that reason, this study re-examines the text of Yorozu no humihougu 万の文反古 using a quantitative approach.

III. Database of Saikaku's Works
Table I shows part of the 578,617-word database used for this analysis (beginning with Yorozu no humihougu 万の文反古). We morphologically analyzed all of Saikaku's 23 works. This database is the only one on Saikaku’s works at present and has a high degree of reliability.

IV. Analysis
In general, Saikaku’s works are made up of many short stories(chapters). We used information of each chapter in our analysis. Then, we compared Yorozu no humihougu 万の文 反古 to Kousyoku ichidai otoko 好色一代男, as an authenticated work of Saikaku.

Figure I.
Boxplot (the top six most common classes)

The basic analysis considers appearance ratio of words by grammatical class, using the top six most common classes: nouns, particles, (main) verbs, auxiliary verbs, adjectives, and adverbs for appearance ratio were used in the analysis.

Figure 1 is a boxplot depicting the appearance ratio of these items in both works. We found differences among verbs and particles only.

Furthermore, we examined by welch’s t-test at the 0.05 significance level. It concluded that in Yorozu no humihougu 万の文反古 and Kousyoku ichidai otoko 好色一代男 of verbs and particles using way is different.

Figure II represents the results of the analysis on appearance rate, using principal component analysis (PCA) with a correlation matrix. The horizontal axis shows the importance of first principal component and the vertical axis, the second. Proportion of variance the first principal component is 0.34, while the second is 0.29; the cumulative prpportion up to the second principal component is 0.64.

PCA results for Yorozu no humihougu 万の文反古 and Kousyoku ichidai otoko 好色一代男 (the top six most common classes)

In Figure II, indicating differences revealed by PCA, Yorozu no humihougu 万の文反古 is on the left and Kousyoku ichidai otoko 好色一代男 on the right.

Upon examining the principal component vector, we find that verbs, adverbs, auxiliary verbs, attributes, and adjectives affect in a positive direction, while particles and nouns affect in a negative direction. (Table II).

Yorozu no humihougu 万の文反古 showed a high appearance ratio for verbs and nouns, while Kousyoku ichidai otoko 好色一代男showed a high appearance ratio for auxiliary verbs, particles, and adjectives (Table II). Therefore, it can be said that the appearance ratio of attached words is high in Kousyoku ichidai otoko 好色一代男 compared to that in Yorozu no humihougu 万の文反古.

V. Conclusion
In this study, two works attributed to Saikaku, Yorozu no humihougu 万の文反古 and Kousyoku ichidai otoko 好色一代男, were compared and analyzed for word class appearance ratios. Significant differences were found.

However, it can be argued that the content and date of each work written will influence word class appearance ratios. Thus, we need to consider this issue from other perspectives and using other data.
