What is Antinatalism?: Definition, History, and Categories (2021)
Antinatalism is the thought that all human beings or all sentient beings should not be born. In this paper, I briefly summarize the history of antinatalistic thoughts and propose a set of categories on antinatalism and related thoughts.

A Solipsistic and Affirmation-Based Approach to Meaning in Life (2019)
In this paper, I make two arguments: 1) There is a solipsistic layer in meaning in life, and 2) the heart of meaning in life can be dynamically incorporated into the affirmation of having been born into this world, which I call “birth affirmation.”

Philosophy, Manga, and Ōmori Shōzō (2018)
An examination of Morioka's Manga Introduction to Philosophy and Ōmori Shōzō's philosophical writings. With Pierre Bonneels.

The Trolley Problem and the Dropping of Atomic Bombs (2017)
In this paper, 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, and secondly, I discuss five aspects of “the problem of the trolley problem".

Is Meaning in Life Comparable?
: From the Viewpoint of ‘The Heart of Meaning in Life’
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 demonstrate that “the heart of meaning in life” cannot be compared with other people’s meaning in life.

Feminism, Disability, and Brain Death: Alternative Voices from Japanese Bioethics (2015)
In this paper, the ideas of “the swaying of the confused self” in the field of feminism, “inner eugenic thought” concerning disability, and “human relationship-oriented approaches to brain death” that appeared in Japanese bioethics are discussed.

A Phenomenological Study of “Herbivore Men” (2013)
"Herbivore men" is a term that became a buzzword in Japan in 2008-2009. It refers to gentle young men who are not very assertive in love and sex. This paper illustrates the outline of this phenomenon from the viepoint of gender studies.

How a Japanese Philosopher Encountered Bioethics (2013)
I 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.

Why is It Hard for Us to Accept Moral Bioenhancement?: Comment on Savulescu’s Argument (2013)
This paper criticizes Julian Savulescu and his colleagues’ argument on moral bioenhancement. Our personality ought to be constructed upon our inner foundation, which should not be tampered with by outside intervention or control, and I dare say this belief is a healthy one that should not be overturned.

Human Dignity and the Manipulation of the Sense of Happiness: From the Viewpoint of Bioethics and Philosophy of Life (2012)
A life with dignity means a life in which we are able to explore our own life, equipped with both happiness and unhappiness, without regret, through relationships with others, without being exploited by the desires of anyone, and without being dominated by our own desires.
