The Perspective of Śūnyatā — AI Research Notes 2
Japanese Perspectives on Śūnyatā
Modern Japanese Buddhist studies of śūnyatā have followed a very different path of development from those in Europe and America.
After the Meiji Restoration in the late 19th century, Japan introduced Western methods of textual criticism and historical research. This allowed Japanese Buddhist studies to move beyond the traditional limits of sectarian commentaries and gave rise to the famous field of modern Buddhist studies.
The major strength of Japanese scholars is that they possess both a deep tradition of studying Chinese Buddhist scriptures and advanced skills in comparing Sanskrit and Tibetan texts. At the same time, they engage with Western philosophy, especially German philosophy and phenomenology, including thinkers such as Hegel and Heidegger.
As a result, Japanese research on śūnyatā combines extremely rigorous textual scholarship with profound philosophical development.
Generally speaking, modern Japanese studies of śūnyatācan be divided into three major approaches and traditions:
1. Textual Scholarship and Historical Criticism: Recovering Nāgārjuna’s Understanding of Śūnyatā
The founders of modern Japanese Buddhist studies were among the first to compare Sanskrit and Tibetan sources in order to clarify the historical development of śūnyatāin Indian Buddhism.
Junjirō Takakusu and Taiken Kimura
As pioneers, they introduced Western historical-critical methods into Japan.
They transformed the study of śūnyatā from the Abhidharma concept of “the existence of dharmas” in early Buddhist schools into the Mahāyāna concept of “the emptiness of dharmas”,
establishing a historical framework for its development.
Hakuju Ui
Ui emphasized that śūnyatā must be understood through Nāgārjuna’s Sanskrit texts, such as the Mūlamadhyamakakārikā.
He argued that śūnyatā cannot be discussed separately from dependent origination.
Śūnyatā means the lack of intrinsic nature (svabhāva).
It is an objective observation of reality, not a metaphysical substance behind the world.
Susumu Yamaguchi
As an internationally recognized Sanskrit scholar, Yamaguchi systematically studied and compared Indian and Tibetan commentaries, including those of Sthiramati and Piṅgala (Qingmu).
He clarified the philosophical debates between the Madhyamaka and Yogācāra schools regarding śūnyatāand existence.
His research demonstrated the central role of śūnyatā in the development of Indian Mahāyāna Buddhism.
2. Philosophical Development: The Kyoto School’s “Absolute Nothingness” and Śūnyatā
This is Japan’s greatest contribution to global philosophy.
Led by Kitarō Nishida, the Kyoto School attempted to bring together Zen Buddhism, Madhyamaka śūnyatā, and Western philosophy—especially Heidegger and existentialism—creating a modern philosophical interpretation of śūnyatā.
Kitarō Nishida: “Place Logic” and “Absolute Nothingness”
Although Nishida did not focus directly on Buddhist texts, he developed the concept of “Absolute Nothingness” based on the meaning of śūnyatā.
He argued that Western philosophy often understands “being” through a subject-object framework.
In contrast, Eastern ideas of “emptiness” or “nothingness” represent a “place” that includes and transcends the opposition between subject and object.
This “nothingness” does not mean that nothing exists.
Rather, it is the fundamental background from which all things arise and appear.
Shin’ichi Hisamatsu
Hisamatsu placed greater emphasis on the practical dimension of Zen’s understanding of “nothingness.”
He argued that “emptiness” or “nothingness” is not an abstract concept.
Rather, it represents the absolute subjectivity through which human beings overcome alienation and attain true freedom.
Keiji Nishitani (What Is Religion?)
Nishitani was one of the most important thinkers who connected Madhyamaka śūnyatā with existential philosophy.
He argued that Western modern nihilism, such as Nietzsche’s nihilism, is a relative and destructive form of nothingness.
In contrast, Nāgārjuna’s śūnyatā is absolute śūnyatā.
Within śūnyatā, all things are affirmed in their own way.
This means:
“Form is śūnyatā, and śūnyatā is form.”
Śūnyatā goes beyond Western nihilism and reconstructs the meaning of human existence.
3. Contemporary Textual Studies and Philosophical Reflection: From Buddha-Nature to Critical Buddhism
From the middle to late 20th century, Japanese studies of śūnyatā entered deeper philosophical reflection and debate.
Yuichi Kajiyama
Kajiyama was one of the greatest modern scholars of Madhyamaka.
Using modern symbolic logic and philosophy of language, he deeply analyzed the logical structures of Nāgārjuna, Bhāviveka, Candrakīrti, and others.
He argued that Madhyamaka śūnyatā is a form of anti-essentialist philosophy of language.
Its core method is to use language to prevent language itself from being turned into an independent reality.
The Debate of Critical Buddhism (Hakamaya Noriaki and Matsumoto Shirō)
In the late 1980s, these two scholars from the University of Tokyo and Komazawa University initiated a debate that attracted international attention in Buddhist studies.
They proposed a radical argument:
“Tathāgatagarbha (Buddha-nature) thought is not Buddhism.”
They argued that the true spirit of Buddhism is Nāgārjuna’s teaching of dependent origination and śūnyatā—the complete rejection of any permanent essence, underlying substance (dhātu), or universal self.
They criticized East Asian traditional ideas of original enlightenment—the belief that all beings possess Buddha-nature and all things are manifestations of true reality—as essentially a transformed form of ātman metaphysics.
They believed such ideas departed from early Buddhism’s teachings of śūnyatā and non-self.
This debate greatly stimulated international discussions about the relationship between śūnyatā and ontology.
Comparison Between Western and Japanese Studies
When comparing the two approaches, an interesting contrast appears:
Western Scholarship
Western scholars are especially skilled at using modern analytic philosophy and philosophy of language—such as Wittgenstein and Derrida—to analyze Nāgārjuna.
They often view śūnyatā as a logical tool or a method for challenging assumptions about knowledge and reality.
Japanese Scholarship
Japanese scholars combine a strong tradition of textual scholarship with German and French existential philosophy.
They not only carefully examine the precise meanings of Sanskrit, Tibetan, and Chinese Buddhist terms, but also attempt to use śūnyatā to engage with thinkers such as Heidegger and Nietzsche in addressing the ultimate crisis of human existence.
