There is a specific smell that constitutes, for me, the most complete sensory summary of what a Japanese morning is.
It is the smell of fish grilling. Specifically, salted salmon or mackerel on the small fish grill that slides beneath the gas burner in a Japanese kitchen, at approximately seven o’clock in the morning, while the rice is finishing in the cooker and the miso soup is simmering on the adjacent burner. The specific combination of the char of fish skin beginning to crisp, the specific fat rendering from the flesh beneath, and the salt that has been drawn to the surface crystallising in the heat — this is a smell that I associate so completely with the specific warmth and the specific safety of a Japanese morning at home that encountering it unexpectedly in an unfamiliar context produces an immediate and involuntary response that is not quite nostalgia but is very close to it.
The Japanese practice of eating fish for breakfast — specifically grilled, specifically salted, specifically as the protein component of the specific washoku breakfast that I described in the breakfast article — is one of the most specifically Japanese of all Japanese food practices and one that is genuinely unusual in international terms. Most food cultures do not grill fish at seven in the morning. Most food cultures reserve fish for lunch and dinner. The Japanese practice of beginning the day with the specific flavour, the specific aroma, and the specific nutritional richness of grilled fish is specific to Japan in ways that deserve careful examination.
The Tradition: Why Fish for Breakfast?
The specific Japanese tradition of eating fish at breakfast is rooted in the specific geography, the specific history, and the specific dietary philosophy of the Japanese islands.
Japan is a archipelago — a collection of islands surrounded by ocean — and fish has been the primary protein source of the Japanese population for most of recorded history. The specific Buddhist dietary restrictions that prohibited the consumption of four-legged animals for most of the period from the seventh century CE through the Meiji period did not apply to fish (fish being considered a different category of creature from the mammals that the restrictions specifically addressed), making fish the specific permitted animal protein that Japanese cooking developed around.
The specific breakfast fish tradition: in the specific context of a Buddhist-influenced dietary culture in which fish was the primary animal protein and in which the daily meal structure was three meals of rice — morning, midday, and evening — the morning meal’s protein was necessarily fish. The specific practice of grilling salted fish for breakfast is not a deliberate cultural choice in the sense of a considered decision to do something specific; it is the accumulated practical result of centuries of specific eating conditions that made fish at breakfast the correct, available, and nutritionally sound option.
The salt-curing dimension: the specific saltiness of most Japanese breakfast fish — the shiozake (salted salmon), the saba shioyaki (salted grilled mackerel), the hokke hiraki (split and salted Atka mackerel) — is not merely a seasoning choice. In the era before refrigeration, salting was the specific preservation method that made fish available for breakfast; the fish was salted the night before or purchased pre-salted from the fishmonger and stored until morning. The specific flavour of salt-cured fish — the way the salt draws moisture from the flesh, concentrating the flavour, creating the specific texture of properly salted fish — is the specific flavour that Japanese breakfast fish is supposed to have.
The Specific Fish: What Japanese People Eat for Breakfast
Shiozake (塩鮭 — salted salmon). The most widely consumed breakfast fish in contemporary Japan, particularly in eastern Japan. Salmon — specifically the shirozake (white salmon, also called keta salmon) that has been the traditional salmon of Hokkaido fishing — is salted and sometimes dried partially before sale. The specific shiozake used for breakfast exists in a spectrum of saltiness levels: kara-shio (からしお — heavy salt), chūkara (中辛 — medium salt), and amashio (甘塩 — light salt). The heavy-salt version is the most traditional and produces the most concentrated flavour; the light-salt version has become more popular as dietary awareness of sodium intake has increased.
The specific excellence of well-grilled shiozake: the skin crisps to the point at which it can be eaten (the specifically crispy salmon skin that is a standard enjoyment of well-grilled shiozake), the flesh is moist and flaky, and the specific combination of the salmon’s fat and the salt produces a flavour that is simultaneously rich and clean — the richness from the fat, the cleanliness from the salt.
Saba (鯖 — mackerel). The most specifically Japanese of all breakfast fish and the one whose specific flavour is most strongly associated with the traditional Japanese breakfast. Mackerel has a specific intensity of flavour — a specific oiliness, a specific briny depth — that is more pronounced than salmon and that requires the specific balance of salt and cooking technique to express correctly.
The specific preparation: mackerel is sold as saba shioyaki (塩焼き鯖 — salt-grilled mackerel, whole or in half-cut pieces), with the salt applied the night before or purchased pre-salted from the fish section of the supermarket. The grilling produces the specific crispy skin and the specific rendered fat that mackerel at its best has, and the specific flavour of the combination — the oily richness of the mackerel flesh and the salt crust — is the most specific and the most beloved of all Japanese breakfast fish flavours.
Hokke (ホッケ — Atka mackerel). The hokke hiraki (ほっけひらき — split Atka mackerel) is one of the most popular izakaya fish preparations and is also widely eaten for breakfast in the Hokkaido region and in households that prefer a milder, more delicate flavour than saba. The specific preparation: the fish is split open along the backbone, salted, and dried slightly before sale, then grilled flat under the broiler. The result has the specific combination of the fish’s mild, slightly sweet flesh and the specific salt-dried concentration of flavour that the drying process produces.
Aji (鯵 — horse mackerel). The specific small, affordable, excellent fish that is one of the most beloved of all everyday Japanese breakfast fish. The horse mackerel at breakfast is typically the aji no hiraki (鯵の開き — butterfly-cut dried horse mackerel), which has been split and dried before sale. The drying concentrates the specific flavour of the aji in a way that fresh fish cannot achieve, and the specific combination of the dried surface’s slightly chewy texture and the moist interior flesh is one of the most specifically satisfying of all breakfast fish eating experiences.
Sanma (秋刀魚 — Pacific saury). The specific autumn fish — its season runs from approximately September through November — that is the most celebrated seasonal breakfast fish in Japan. The specific quality of fresh sanma: an extraordinary richness of omega-3 fatty acids that produces a specific fatty, slightly bitter, deeply savoury flavour when grilled. The specific ritual of eating sanma: the fish is grilled whole, served with grated daikon (which cuts through the fat), soy sauce, and lemon, and the flesh is removed from the skeleton at the table — a specific eating engagement that is itself part of the pleasure.
The Fish Grill: Japan’s Most Specific Kitchen Appliance
The specific Japanese kitchen appliance that makes breakfast fish possible in the Japanese home is the fish grill — the sakana guriru or more commonly guriru — that is built into the standard Japanese gas range as a pull-out drawer beneath the main burners.
The fish grill is a specific small broiler — a wire rack inside a shallow tray, with a gas burner above it — that heats to very high temperature quickly and that is sized specifically to accommodate one to three pieces of fish. The specific design: the wire rack allows fat rendered from the fish to drip into the tray below rather than accumulating around the fish, producing the specific crispy rather than steamed result that separates excellent breakfast fish from merely adequate breakfast fish.
The fish grill’s specific operational requirements: the rack must be lightly oiled before placing the fish, to prevent sticking; the fish should be placed skin-side down first (for most preparations); the timing varies by fish thickness and by the specific degree of doneness desired; and the tray must be cleaned after each use, which is the specific domestic inconvenience that has made some Japanese households reluctant to use the fish grill regularly despite owning one.
The specific smell that the fish grill produces — which permeates the kitchen, the adjacent rooms, and often the hallway outside the apartment — is the specific social reality of Japanese breakfast fish in the dense urban living environments of Japanese cities. The apartment building in which everyone eats breakfast fish simultaneously at seven o’clock on a weekday morning produces a specific collective aroma that is, for the people who grew up with it, the smell of morning itself.
The Young People Problem: Is Breakfast Fish Disappearing?
The specific question of whether Japanese breakfast fish culture is being maintained by younger generations is one of the more melancholy food culture questions in contemporary Japan.
The specific trends: surveys of Japanese dietary habits consistently show that the proportion of Japanese people who eat fish for breakfast is declining among younger age groups. The specific factors: younger Japanese people in urban environments are more likely to eat toast and coffee for breakfast (the specific yōshoku breakfast culture I described in the breakfast article) or to skip breakfast entirely. The specific domestic skills required to prepare fish for breakfast — the specific timing of the grill, the specific technique for removing the fish from the rack without breaking it — are becoming less widely distributed as fewer young people have learned them from their parents.
The convenience alternatives: pre-cooked breakfast fish — hinedon (the small single-serving vacuum-packed grilled fish portions that can be heated in a microwave or in a pan) — have made breakfast fish somewhat more accessible for people who lack the time or the skill to grill from fresh. The convenience of the pre-cooked alternative is real, and its adoption represents a specific compromise between tradition and the specific demands of contemporary Japanese life.
The cultural continuity: despite these trends, breakfast fish remains a standard component of the Japanese washoku breakfast culture, and it is unlikely to disappear as long as the traditional breakfast format itself persists. The ryokan that serves its guests grilled fish for breakfast each morning is maintaining a tradition that is genuinely valued by the guests who choose to stay there precisely because of what it represents: the specific morning flavour of Japan at its most specifically Japanese.
