Shu Matsui (松井周): Excavating the Darkness Within the Family
Introduction
Every family has its secrets. Most theater is content to hint at these secrets, to suggest the darkness that lurks beneath domestic surfaces without examining it too closely. Shu Matsui (松井周) is not most theater. As the founder and artistic director of the theater company Sample, Matsui has built a career on the unflinching excavation of family dysfunction, social deviance, and the disturbing impulses that conventional society works so hard to suppress.
Matsui won the 55th Kishida Kunio Drama Award in 2011 for A Son to Be Proud Of (自慢の息子), a play that took the familiar dramatic territory of the family and transformed it into something genuinely unsettling. His work does not offer the comfort of resolution or the reassurance of moral clarity; instead, it forces audiences to confront the uncomfortable truth that the line between "normal" and "deviant" behavior is far more blurred than we like to believe.
Early Life and Career
Born in 1972, Shu Matsui spent formative years as a member of the legendary theater company Seinendan (青年団), led by the influential director and playwright Oriza Hirata. Seinendan was the epicenter of the "quiet theater" (shizuka na engeki) movement, which sought to create plays that mimicked the rhythms and textures of everyday conversation with meticulous naturalism.
Matsui absorbed Seinendan's commitment to observational precision and naturalistic performance, but he was drawn to subject matter that was far darker than the gentle domestic scenarios that characterized much of the quiet theater movement. Where Hirata found theatrical richness in the ordinary, Matsui found it in the extraordinary -- the moments when ordinary behavior tips into something strange, compulsive, or transgressive.
He founded Sample as a vehicle for exploring this darker territory. The company name suggests both a scientific specimen and a representative example -- fitting for a theater project that treats human behavior as something to be observed, collected, and examined under theatrical magnification.
With Sample, Matsui developed a theatrical approach that combined the surface naturalism he had learned at Seinendan with subject matter that was anything but comfortable. His plays depicted families and social groups in which the norms of acceptable behavior had been subtly distorted, creating worlds that looked and sounded familiar but felt deeply, inexplicably wrong.
The Kishida Prize-Winning Work
A Son to Be Proud Of (自慢の息子) -- 55th Kishida Kunio Drama Award, 2011
A Son to Be Proud Of takes the most conventional of dramatic subjects -- a parent's pride in their child -- and subjects it to devastating scrutiny. The title's straightforward sentimentality is deliberately misleading; the play reveals how parental pride can curdle into obsession, how family love can become a mechanism of control, and how the desire to produce a child worthy of pride can distort both parent and child beyond recognition.
The play depicts a family system in which the conventional relationships between parents and children have been warped by pressures -- social, psychological, and possibly pathological -- that are never fully explained. Matsui is not interested in providing neat psychological diagnoses or sociological explanations for his characters' behavior. Instead, he presents the behavior itself, in all its strangeness and specificity, and trusts the audience to find their own meanings.
What makes A Son to Be Proud Of so disturbing is its refusal to position the audience safely outside the dysfunction it depicts. The family in the play is not presented as a grotesque exception to normal family life; rather, Matsui suggests that the dynamics he depicts -- the possessiveness, the manipulation, the conflation of love and control -- are present to some degree in all families. The play simply removes the filters and social conventions that normally keep these dynamics hidden.
The Kishida Prize committee recognized the play for its psychological depth, its theatrical craft, and its ability to use the family as a lens for examining deeper questions about human nature, social conformity, and the thin membrane separating acceptable behavior from deviance.
Theatrical Style and Philosophy
Matsui's theatrical work is defined by several distinctive characteristics:
-
Naturalistic surface, disturbing depth: His plays typically begin in a recognizable, seemingly ordinary social situation and gradually reveal layers of strangeness and dysfunction beneath the surface. The naturalistic performance style makes the disturbing content more unsettling, not less -- because it is presented without the distancing effects of stylization or exaggeration.
-
Family as laboratory: The family unit serves as Matsui's primary site of investigation. He treats the family not as a source of warmth and belonging (though those elements may be present) but as a closed system in which power dynamics, psychological dependencies, and behavioral pathologies can be observed in concentrated form.
-
Ambiguity and withholding: Matsui deliberately withholds explanatory information from his audiences. Characters' motivations are opaque, their histories are incomplete, and the "reasons" behind their behavior are never fully revealed. This ambiguity forces audiences into an active, interpretive engagement with the work.
-
The body and its betrayals: Physical behavior in Matsui's plays often tells a different story than the spoken dialogue. Characters' bodies reveal desires, anxieties, and impulses that their words attempt to conceal. This disjunction between verbal and physical communication creates a pervasive sense of unease.
-
Social deviance as mirror: Rather than treating deviant behavior as aberrant or exotic, Matsui presents it as a magnified version of impulses that exist within all social behavior. His plays challenge audiences to recognize the continuity between their own "normal" behavior and the "abnormal" behavior they see on stage.
Major Works
Matsui's body of work with Sample includes:
-
A Son to Be Proud Of (自慢の息子, 2010) -- His Kishida Prize-winning exploration of parental pride, family dysfunction, and the distortions of love.
-
Numerous productions with Sample that explore themes of family pathology, social deviance, power dynamics, and the hidden forces that shape human behavior within intimate groups.
-
Works that have been presented at major theaters and festivals across Japan, establishing Sample as one of the most intellectually stimulating companies in Japanese contemporary theater.
-
Collaborative projects that bring his distinctive sensibility into dialogue with other artists and artistic traditions.
-
Post-Seinendan works that demonstrate how the techniques of "quiet theater" can be applied to disturbing and unconventional subject matter, expanding the range of what naturalistic performance can express.
Legacy and Influence
Shu Matsui's contribution to Japanese theater is significant in several areas:
-
Darkening the quiet theater: He has demonstrated that the naturalistic techniques pioneered by the quiet theater movement can be applied to material that is far darker and more disturbing than the gentle domestic scenarios typically associated with that style. This expansion of naturalism's range has been influential for younger playwrights.
-
Challenging comfort zones: His work consistently pushes audiences beyond their comfort zones, creating theatrical experiences that linger in the mind long after the performance ends. This commitment to discomfort as a creative tool has contributed to a more challenging and intellectually adventurous theater culture.
-
Family as critical concept: By treating the family as an object of critical examination rather than sentimental celebration, Matsui has contributed to important cultural conversations about the nature of family life in Japan and the pressures it places on individuals.
-
Ethical complexity: His refusal to moralize or provide easy answers about human behavior models a kind of ethical complexity that is rare in contemporary theater, encouraging audiences to think for themselves rather than accepting pre-packaged moral conclusions.
-
Training ground: Sample has served as an important training ground for actors and theater-makers who have gone on to influential careers of their own, extending Matsui's artistic influence into the broader theater community.
