The Music Executive & the Mountain Terroir

The story of Domaine Hase begins not in a vineyard but in a recording studio — or rather, in the offices, concert halls, and backstage corridors of the Japanese music industry, where Mitsuhiro Hase built a successful career before wine ever entered his life. He was not born into a farming family; he had no inherited vineyard, no childhood memories of harvest, no ancestral connection to the soil of Nagano. What he had was a career in music — a world of creativity, performance, and the relentless pursuit of artistic expression — and a growing conviction, born from years of tasting and travelling, that wine could offer the same kind of creative fulfilment that music had provided. In 2014, at an age when most professionals are consolidating their positions rather than abandoning them, Mitsuhiro made the decision that would transform his life: he left the music industry and committed himself fully to the study of viticulture and winemaking.

His preparation was thorough and international. He enrolled at Arc-En-Vigne, the renowned French wine school, where he absorbed the technical foundations of the craft: soil science, vine physiology, fermentation chemistry, and the thousand small disciplines that separate amateur enthusiasm from professional competence. But classroom learning was not enough. Mitsuhiro sought out the masters of Japanese natural wine, and found them in Hokkaido — at 10R Winery in Iwamizawa, the pioneering estate founded by Bruce Gutlove and Kazuyuki Nakazawa that had proven that world-class natural wine could be made from 100% Japanese grapes in extreme conditions. Under Gutlove's mentorship, Mitsuhiro learned not merely technique but philosophy: the understanding that the best wines are those that require the least manipulation, that the vigneron's role is to create the conditions for the grapes to express their true character, and that natural winemaking is not a rejection of science but a refinement of it — the application of knowledge in service of restraint rather than control.

The training at 10R Winery was transformative. Bruce Gutlove, an American winemaker who had become one of the most respected figures in Japanese natural wine, taught Mitsuhiro the practical application of the principles he had studied in France: wild yeast fermentation, minimal sulfur, organic viticulture, and the patient observation of fermentation as a living process rather than an industrial procedure. The extreme conditions of Hokkaido — the cold, the short growing season, the necessity of working with indigenous varieties — provided a rigorous training ground that would prove essential when Mitsuhiro returned to Nagano to establish his own estate. He learned that natural winemaking is not a luxury of favourable climates; it is a necessity in challenging ones, where the vigneron must work with nature rather than against it, leveraging the unique characteristics of place rather than imposing a predetermined style upon it.

In 2017, Mitsuhiro established Domaine Hase in Fukuihara, Takayama Village, Nagano Prefecture — a region of extraordinary natural beauty and viticultural potential that had been overshadowed by the more established wine regions of Yamanashi and Hokkaido. He chose Fukuihara for its altitude — 800 metres above sea level — its cool climate, its clean mountain air, and its proximity to the Japanese Alps, which provide both dramatic scenery and a moderating influence on temperature that is ideal for slow-ripening, high-acidity wines. The name "Domaine Hase" reflects the French training and the Burgundian philosophy that guides the estate; the parallel "Hikaru Farm" (光る農園 — "Shining Farm") represents the agricultural foundation, the organic viticulture that is the prerequisite for everything that happens in the cellar. Together, they form a single enterprise: farm and winery, vineyard and cellar, earth and bottle, united by one man's journey from music to wine, from city to mountain, from performance to terroir.

At Domaine Hase, the winemaking philosophy is expressed in two words: "simple vinification." This is not simplicity as naivety or lack of technique; it is simplicity as discipline, as the deliberate reduction of intervention to the absolute minimum necessary to allow the grapes to express their true character. The winery seeks to maximise the power of the grapes through natural fermentation using wild yeasts — the indigenous populations that live on grape skins, in the vineyard air, and on the surfaces of the cellar — striving for a winemaking style with minimal human intervention. No additives, no enzymes, no selected yeast strains, no tannin powders, no acid adjustments. The wine is what the grape, the yeast, and the terroir make it, with Mitsuhiro's role limited to creating the conditions for this natural transformation and guiding it with patience and observation rather than controlling it with technology and chemistry.

The wild yeast fermentation is the technical and philosophical core of the estate. In conventional winemaking, fermentation is initiated by inoculating the must with laboratory-cultured yeast strains selected for their predictable behaviour, rapid fermentation, and neutral aromatic profile. At Domaine Hase, this industrial approach is rejected entirely. The yeasts that ferment the grapes are the same yeasts that live in the vineyard — microorganisms that have evolved in symbiosis with the Fukuihara environment, adapted to the cool mountain climate, and capable of initiating and completing fermentation without human assistance. Because wild yeasts ferment more slowly and less predictably than selected strains, the process requires meticulous attention: daily tasting, temperature monitoring, and the patience to allow each tank to develop at its own pace. Some fermentations are fast and vigorous, others slow and contemplative; each is allowed to find its own rhythm, its own equilibrium, its own expression of the vintage and the variety.

Sulfur is kept to an absolute minimum — not eliminated entirely, as in the most radical natural wineries, but reduced to the lowest levels consistent with stability and longevity. This is a pragmatic rather than dogmatic position: Mitsuhiro understands that some sulfur is necessary to protect the wine from oxidation and microbial spoilage, particularly in a humid climate where the risks of volatile acidity and bacterial contamination are real. But the sulfur is used as a preservative, not as a mask — not to sterilise the wine into submission, not to standardise flavour, not to compensate for flawed fruit or dirty cellar practices. The grapes are healthy, the cellar is clean, the fermentation is sound; the sulfur is merely a gentle safeguard, a whispered reminder to the wine to remain true to itself rather than a shouted command to conform to an industrial standard.

The white wines of Domaine Hase demonstrate the clarity and precision that this philosophy can achieve. The Chardonnay — fermented and aged in a combination of stainless steel and neutral oak — shows the mountain terroir in every glass: citrus and stone fruit, a mineral backbone, and the saline finish that is the Fukuihara signature. The Riesling, with its high natural acidity and floral aromatics, achieves a balance of sweetness and tension that is rare in Japanese Riesling — not the simple, sugary wines of industrial production, but a wine of complexity and depth that rewards attentive drinking. The Gewürztraminer, with its exotic spice and lychee perfume, is handled with particular restraint; the wild yeast fermentation tempers the variety's natural exuberance, producing a wine that is fragrant but not cloying, expressive but not overwhelming. And the Sauvignon Blanc — a variety that in warmer climates can become aggressively herbaceous and acidic — finds a gentler expression at 800 metres, with the cool nights preserving its citrus freshness while the slow ripening develops a roundness and texture that is unexpected and welcome.

The red wines are equally distinctive. The Pinot Noir — the variety that Mitsuhiro trained with at 10R Winery in Hokkaido — expresses the Fukuihara terroir with transparency and finesse. Whole-cluster fermentation, gentle extraction, and ageing in neutral oak produce a wine of pale ruby colour, red berry and cherry fruit, and a savoury, earthy undertone that speaks of the mountain soil. The Cabernet Franc, with its natural herbaceousness and peppery spice, is transformed by the altitude into something more refined: the green notes are moderated, the fruit is concentrated, and the tannins are fine and integrated rather than aggressive and astringent. And the Muscat Bailey A — the Japanese hybrid that is the estate's most original contribution — produces wines of surprising elegance: light-bodied, floral, and gently spiced, with the strawberry and rose petal aromatics that make the variety so distinctive, and a freshness and drinkability that make it the perfect introduction to the Domaine Hase style. These are not wines for collectors seeking power and concentration; they are wines for drinkers seeking pleasure, compatibility, and the honest expression of a specific place.

To understand Mitsuhiro Hase, one must understand the trajectory that brought him from the music industry to the mountains of Nagano — not as a retreat or an escape, but as a continuation of the same creative impulse that had driven his earlier career. Music and wine are not as different as they appear: both are arts of time, of patience, of the slow development of complexity from simple beginnings. A song is not created in a moment but built note by note, layer by layer, until the whole emerges from the accumulation of its parts. A wine is not made in a day but grown vine by vine, fermented tank by tank, aged barrel by barrel, until the bottle contains not merely grape juice but the accumulated expression of a place, a season, and a maker's vision. Mitsuhiro did not abandon creativity when he left music; he transferred it from one medium to another, from the concert hall to the vineyard, from the recording studio to the cellar.

The discipline of the music industry — the relentless pursuit of perfection, the attention to detail, the understanding that small errors compound into large failures — serves Mitsuhiro well in winemaking. The music executive learns to listen: to hear the subtle dissonance that mars a mix, the timing error that throws off a rhythm, the tonal imbalance that separates a good recording from a great one. The winemaker learns the same attentiveness: to taste the slight volatile acidity that signals bacterial contamination, to smell the premature oxidation that indicates flawed fruit, to observe the fermentation that is proceeding too fast or too slow and to know, from experience and intuition, when to intervene and when to wait. Mitsuhiro's years in music taught him to trust his senses, to develop the patience that creative work demands, and to understand that the best results often come from restraint rather than effort — from knowing when to stop adding, when to let the material speak for itself, when to step back and allow the work to complete itself.

The mountain silence of Fukuihara is the opposite of the music industry's noise — the constant travel, the crowded venues, the endless meetings and negotiations and compromises. In Takayama Village, the silence is physical and psychological: the absence of traffic, of crowds, of the urgent demands that characterise urban professional life. This silence is not empty; it is full — full of the sounds that urban life drowns out: the wind in the vines, the birds in the forest, the subtle changes in fermentation that a quiet cellar allows the vigneron to hear. Mitsuhiro has spoken of the peace he found in this silence, the clarity that comes from working with his hands in the soil rather than his mind in meetings, the satisfaction of creating something tangible and lasting rather than something ephemeral and consumed. The wine he makes is a product of this silence — not loud, not flashy, not demanding attention, but rewarding the attentive drinker with depth, complexity, and the quiet intensity that is the signature of the estate.

The future of Domaine Hase is tied to the maturation of the vineyard and the deepening of Mitsuhiro's understanding of the Fukuihara terroir. As the vines age — the Pinot Noir, the Chardonnay, the Riesling, the Cabernet Franc, the Muscat Bailey A — they will develop the root systems, the trunk girth, and the physiological maturity that produce grapes of greater concentration and complexity. The wines will evolve, vintage by vintage, as Mitsuhiro learns which blocks perform best in which years, which varieties express the terroir most clearly, which techniques enhance and which diminish the natural character of the fruit. The umami depth that is the estate's most distinctive characteristic will become more pronounced, more reliable, more understood — a signature that identifies Domaine Hase wines as surely as a fingerprint identifies a person. And the estate's reputation, already growing within Japan's natural wine community, will extend internationally, as the unique qualities of high-altitude Nagano viticulture become recognised alongside the more established regions of Yamanashi, Hokkaido, and Yamagata.

In an age of industrial wine production, of homogenised flavours and marketing-driven branding, Domaine Hase stands as a radical alternative — a small estate carved from mountain wilderness, farmed by a former music executive who learned his craft in France and Hokkaido, producing wines of quiet intensity and authentic expression from grapes grown at 800 metres in the Japanese Alps. Mitsuhiro Hase is not merely making wine; he is making a life, a place, a future — one vine at a time, one fermentation at a time, one bottle of umami-rich, mineral-laced, mountain-expressed wine at a time. His journey from music to wine is not a departure but a continuation — the same creative impulse, the same attention to detail, the same patience and restraint, transferred from one art to another. And the wines that emerge from this journey are not merely beverages; they are compositions — structured, layered, evolving, and ultimately resolving into something that is both beautiful and true. The mountain silence, the wild yeast, the minimal sulfur, the patient ageing: these are the instruments of Mitsuhiro's new art, and the music they make is the taste of Fukuihara — Japanese citrus, tropical fruit, minerals, salinity, and the umami of dashi, the fifth taste that only time and terroir can create.
