An articulation of the method common to Flower Rites, Obsession, Transition, Resilient Bloom, and Two Hearts — and of the distinct psychological and bodily conditions each series investigates.
The method has five components that appear in every series, in different ratios. They are constants. What changes between series is not the method but the condition being investigated.
This is the foundation, and it is where most painting differs from this practice. In conventional painting, the hand executes what the mind has decided. Here, the entire body is the apparatus — posture, breath, weight transfer, the kimono, the stance borrowed from martial arts. The hand is one node in a much larger system. A painting can be made without conscious recollection of specific gestures: the decision-making is distributed across the whole body, not centralized in the cognitive mind directing the hand.
The underlying principle is 心技体 (shin-gi-tai): mind, technique, and body as a unified field rather than three things to coordinate.
This is the most distinctive technical feature of the work. Brushes here are not neutral delivery devices for a pre-decided mark. The instruments push back: hydrangea flowers, real roses, burned organic matter, Japanese calligraphy brushes, childhood crayons. Each one has its own physical behavior — fragility, absorption, instability, resistance — and that behavior co-authors the mark.
The flower is not simply applying paint; it is altering the paint, altering the gesture, altering what the body can and cannot do at that moment. The tool participates. This makes the painting closer to a duet than a monologue. Full control is neither possible nor desired — partial control is the condition the work needs to operate inside.
The work is not pre-planned. It is not sketched, then executed. It emerges through sustained attention to what is happening on the surface right now, with materials that will not stay still, in a body that is doing something physically demanding.
This is structurally identical to grappling. A grappling sequence cannot be pre-decided because the opponent's body continuously changes the conditions. The same is true of a wet hydrangea on a primed canvas: one responds to what the surface is doing, rather than imposing what one wanted it to do. Martial arts is therefore not a metaphor in this practice — it is the actual underlying skill being applied.
When the same form is painted again and again — roses, chrysanthemums, flowers burned one after another — it is not a series made for the market. Repetition is a research method. Each iteration is a slightly different perceptual experiment: different pressure, different fatigue, different concentration, different emotional state. The work is the accumulated data.
This is closer to scientific method than to traditional studio practice. One parameter at a time is varied, and what happens is observed.
This is the conceptual signature that holds everything together. The canvas is not approached as a space where an image will be constructed. It is approached as a surface that will record an event that happens in front of it.
The painting is the trace, not the goal. The trace of what? Of a temporary convergence: a specific body, in a specific psychological state, working with specific unstable materials, under specific conditions, for a specific duration. Once that convergence ends, the work is what remains.
This is why this practice is closer to performance than to picture-making — and why Two Hearts, which makes the performance explicit, is not a departure from the studio practice but the clearest expression of it.
The five components above are the constants. What changes between series is the condition being investigated. The conditions are distinct from one another and do not all sit in the same register; each names a specific state in which the work is made.
What happens to perception, body, and material when a person enters a sustained state of focused immersion. Not about emotion — about a specific cognitive-bodily state, the heightened attention that ritual produces, drawn from Shinto, from martial arts, from any sustained physical discipline.
Hydrangeas and calligraphy brushes are chosen because they require that state. They cannot be bullied; they must be met.
Residue of an attentional conditionWhat happens when attention is not free but compelled. Where Flower Rites is open and immersive, Obsession is recursive and trapped. The investigation is physically enacted — painting the same rose, again and again, until the difference between desire and exhaustion blurs.
The rose is both image and tool, because obsession collapses the distinction between what one wants and what one uses to get it.
Residue of a compulsive conditionWhat happens when the body must process the transformation of something living into something absent. The condition closest to grief, but more precisely named — not grief, transition: the perceptual and psychological passage from presence to memory.
What does it feel like, in the body, when something that was vital is becoming ash?
Residue of a dissolving conditionWhat happens when a person must occupy two incompatible moral positions at once and refuse to resolve them. Care and stigma. Belonging and exclusion. The "bad" who showed solidarity and the "good" who showed hypocrisy. Being Japanese in Spain.
Monochrome removes the easy emotional cue, forcing the contradiction to live in form alone.
Residue of a non-resolving conditionWhat happens when one sensory channel must be re-rendered in another, across two cultures, in real time, with another person. Sound becomes color. Cultural memory becomes gesture. Translation under live constraint — nothing can be pre-decided because the music has not yet been played.
Residue of a cross-modal, cross-cultural conditionEvery one of these conditions is a state the conscious mind cannot adequately describe but the body can enact. Attention. Compulsion. Loss. Contradiction. Translation.
These are not subjects to be depicted. They are states generated in the body, of which traces are then left behind. The work has integrity across the series even though the surfaces look different — because the underlying project is the same.
To make visible the states of being that exist below or beside language.
This is also why the advice to "pick one style" misses the work entirely. Each condition produces a different surface because each condition operates differently in the body. Compulsion accumulates — its surface is dense, recursive, saturated. Ritual immerses — its surface is open, gestural, color-full. Dematerialization dissolves — its surface is thin, fragile, sparse. Contradiction refuses — its surface is monochrome, formal, withheld.
The visual variation is evidence the method works. If every series looked the same, the work would be decoration with consistent branding, not an investigation of distinct conditions through a consistent method.
Hasegawa's practice uses the body — trained through decades of martial arts — as a perceptual instrument, and unstable organic materials as co-authors, to produce paintings that are the residue of specific psychological and bodily conditions: ritualized attention, fixated repetition, dematerialization, moral contradiction, and synesthetic translation.
Once that argument is made — once — the four series stop looking like four directions and start looking like four chambers of one investigation.
