With this type of books, giving a random evaluation without any criteria seems unfair to me. So I will evaluate all the stories, giving each one a single score, and then calculate the average.
Milk - Daido Tamaki
This opening story has two flaws. The first is that it is poorly written: the perspective of the adolescent protagonist is well-handled, but it still results in being annoying for the reader, not very personal and boring. In short, everything that a perspective should not be. Moreover, and more importantly: where did the author want to go with this? Because I didn't understand.
Score: 3/5.
Inside - Shimamoto Rio
Again, an adolescent protagonist who adds and subtracts nothing from the narration, and above all the same criticism as before. A short story without art or substance that leaves nothing to the reader, asking too much from the few pages available.
Score: 2/5.
Piss - Moroi Yuzuki
Sex, sex, sex... and the content? The psychological characterization? It has disappeared along with the two characters Shin and Misa? The pain of the protagonist does not reach the reader. And yes, she is a prostitute, with an even more horrible life, not a banal office worker! The potential was there, but it went down the drain.
Score: 1/5.
Le labbra del figlio - Uchida Shungiku
One of the best stories, and the amazing thing is... that it doesn't narrate anything at all. Nevertheless, it is very well-written, especially because of the author's ability to handle the language of the characters (the taxi driver and the wife are very realistic).
Score: 4/5.
La stanza - Fujino Chiya
Definitely the best of the stories (as if the competition was high...). Excellent characterization of the protagonist and especially of Kitahara. The only weak point is the end, a bit rushed and thrown there.
Score: 5/5.
Fiesta - Yamada Eimi
I didn't even finish it, it was so bad and boring.
Score: 1/5.
L'uovo infecondo - Hasegawa Junko
Not bad, really. A greater care in writing and in the psychological introspection of the characters would have made it compete with "La stanza" for the best of the collection. More than sufficient, anyway.
Score: 4/5.
L'ombra dell'orchidea - Takagi Nobuko
It started well, but it spoiled itself with the insertion of the supernatural element and the resolution of the question about the relationship between Yukio and his patient. Moreover, the lack of showing, which would be necessary in the description of the spirit, is a serious flaw. Too bad, too bad.
Score: 4/5.
Final considerations
The final average is 2.8, so three stars. In fact, it is the right score. As always in these collections of stories, there is the five-star story next to the one-star or three-star one. If one really wanted to valorize Japanese female narration in Italy, one should have chosen at least more talented authors. Especially in the light of "the eight ways of being a woman in today's Japan": if one reads the book wanting to learn something about the modern Japanese woman, it will be a waste of time. Even reading it to be entertained with a collection of stories, however, it will lead to a waste of time. Useless collection, then, that adds and subtracts nothing from Japanese narration in Italy.
