    What Is Antinatalism?: Definition, History, and Categories
    The Review of Life Studies 12 1-39. 2021.
    The concept of antinatalism is now becoming popular on the Internet. Many online newspaper articles deal with this topic, and numerous academic papers on antinatalism have been published over the past ten years in the fields of philosophy and ethics. The word “antinatalism” was first used in the current meaning in 2006, when the two books that justify the universal negation of procreation were published: one by David Benatar and the other by Théophile de Giraud. However, we can find various pro…Read more

    The Trolley Problem and the Dropping of Atomic Bombs
    Journal of Philosophy of Life 7 (2): 316-337. 2017.
    In this paper, the ethical and spiritual aspects of the trolley problem are discussed in connection with the dropping of atomic bombs on Hiroshima and Nagasaki. First, I show that the dropping of atomic bombs was a typical example of the events that contained the logic of the trolley problems in their decision-making processes and justifications. Second, I discuss five aspects of “the problem of the trolley problem;” that is to say, “Rarity,” “Inevitability,” “Safety Zone,” “Possibility of Becom…Read more

    A Phenomenological Study of “Herbivore Men”
    The Review of Life Studies 4 1-20. 2013.
    From 2008 to 2009, “herbivore men (sôshoku danshi or sôshoku-kei danshi in Japanese)” became a trendy, widely used term in Japanese. It flourished in all sorts of media, including TV, the Internet, newspapers and magazines, and could even occasionally be heard in everyday conversation. As it became more popular its original meaning was diversified, and people began to use it with a variety of different nuances. In December of 2009 it made the top ten list of nominees for the “Buzzword of the Yea…Read more

    This book is a collection of essays on the philosophy of life’s meaning in contemporary society. Topics range from antinatalism, meaning of life, the trolley problem, to painless civilization. I am now writing a comprehensive philosophy book on those topics, but it will take several years to complete; hence, I decided to make a handy book to provide readers with an outline of the philosophical approaches to the meaning of life that I have in mind. Chapter One discusses the definition, history, a…Read more

    The objective of this paper is to contribute to the international discussions on life and scientific technology by examining the images and concepts of life in contemporary Japan. In English the word Inochi can be rendered as "life". However, the nuances of the Japanese term differ in certain cases, and therefore I have chosen to use the term much as is. I first discuss the linguistic meanings of the word, and then consider several important features of the images of inochi that have appeared in…Read more

    Manga Introduction to Philosophy Ch.1 "What Is Time?" Part 1
    with Nyancofu Terada
    Tokyo Philosophy Project. 2021.
    This book was first published in Japanese in 2013 and was warmly welcomed not only by general readers but also by specialists in philosophy. I believe that it succeeded in breaking new ground in the field of introductory approaches to philosophy. Many manga or comic books explaining the thought of major philosophers have already been published. There have also been manga whose story was conceived by philosophers. To the best of my knowledge, however, there has never been a book in which a philos…Read more

    "Confessions of a Frigid Man: A Philosopher’s Journey into the Hidden Layers of Men’s Sexuality" is the translation of a Japanese 2005 bestseller, "Kanjinai Otoko." Soon after the publication, this book stirred controversy over the nature of male sexuality, male “frigidity,” and its connection to the “Lolita complex.” Today, this work is considered a classic in Japanese men’s studies. The most striking feature of this book is that it was written from the author’s first-person perspective. The au…Read more

    Abstract In 1998, the Council for Science and Technology established the Bioethics Committee and asked its members to examine the ethical and legal aspects of human cloning. The Committee concluded in 1999 that human cloning should be prohibited, and, based on the report, the government presented a bill for the regulation of human cloning in 2000. After a debate in the Diet, the original bill was slightly modified and issued on December 6, 2000. In this paper, I take a closer look at this proce…Read more

    In this paper, I would like to argue that brain-dead small children have a natural right not to be invaded by other people even if their organs can save the lives of other suffering patients. My basic idea is that growing human beings have the right to grow in the form of wholeness, and dying human beings also have the right to die in the form of wholeness; in other words, they have the right to be protected from outside invasion, unless they have declared their wish to abandon that right before…Read more

In every country 20 to 40 % of the popularion doubts the idea of brain death. This paper reconsiders the concept, and reports the ongoing rivision process of the current law.

    In this paper, I propose the concept of the “animated persona,” a soundless voice that says, “I am here” and appears on the surface of someone or something. This concept can bring clarity to the experience of perceiving a kind of personhood on a corpse, a wooden mask, or even a tree. In the first half of this paper, I will examine some Japanese literature and a work of Viktor Frankl’s that discuss these phenomena. In the second half, I will analyze the concept of animated persona from five persp…Read more

    If our sense of happiness is closely connected to brain functions, it might become possible to manipulate our brain in a much more refined and effective way than current methods allow. In this paper I will make some remarks on the manipulation of the sense of happiness and illuminate the relationship between human dignity and happiness. The President’s Council on Bioethics discusses this topic in the 2003 report Beyond Therapy, and concludes that the use of SSRIs might make us “feel happy for no…Read more

    The aim of this paper is to propose a new approach to the question of meaning in life by criticizing Thaddeus Metz’s objectivist theory in his book Meaning in Life: An Analytic Study. I propose the concept of “the heart of meaning in life,” which alone can answer the question, “Alas, does my life like this have any meaning at all?” and I demonstrate that “the heart of meaning in life” cannot be compared, in principle, with other people’s meaning in life. The answer to the question of “the heart …Read more

    Narrative responsibility and moral dilemma: A case study of a family’s decision about a brain-dead daughter
    with Takanobu Kinjo
    Theoretical Medicine and Bioethics 32 (2): 91-99. 2011.
    A brain death case is presented and reinterpreted using the narrative approach. In the case, two Japanese parents face a dilemma about whether to respect their daughter’s desire to donate organs even though, for them, it would mean literally killing their daughter. We argue that the ethical dilemma occurred because the parents were confronted with two conflicting narratives to which they felt a “narrative responsibility,” namely, the responsibility that drives us to tell, retell, and coauthor th…Read more

    Feminism, Disability, and Brain Death :Alternative Voices from Japanese Bioethics
    Journal of Philosophy of Life 5 (1): 19-41. 2015.
    Japanese bioethics has created a variety of important ideas that have not yet been reflected on mainstream bioethics discourses in the English-speaking world, which include “the swaying of the confused self” in the field of feminism, “inner eugenic thought” concerning disability, and “human relationship-oriented approaches to brain death.” In this paper, I will examine them more closely, and consider what bioethics in Japan can contribute to the development of an international discussion on phil…Read more

    How a Japanese Philosopher Encountered Bioethics
    In Frank Rövekamp & Friederike Bosse (eds.), Ethics in Science and Society: German and Japanese Views, Iudicium Verlag. pp. 27-41. 2013.
    In this essay I will illustrate how a Japanese philosopher reacted to a newly imported discipline, “bioethics,” in the 1980s and then tried to create an alternative way of looking at “life” in the field of philosophy. This essay might serve as an interesting case study in which a contemporary “western” way of thinking succeeded in capturing, but finally failed to persuade, a then-young Japanese researcher’s mind.

    Painless Civilization and the Fate of Humanity: A Philosophical Investigation
    In Imagining a Common Horizon for Humanity and the Planet, Cappadocia University Press. pp. 59-73. 2023.
    Painless civilization is a term I coined in my Japanese book of the same title, which was published in 2003. Contemporary civilization aims to provide pleasure and comfort and eliminate pain and suffering as much as possible. This is especially evident in advanced countries. Contemporary civilization is moving toward a painless civilization. However, in a painless civilization, we are deprived of the joy of life, which is considered a fundamental source of meaning in life, and we are led toward …Read more
