Shiro shoyu
the amber-pale, wheat-forward soy sauce of Mikawa
Brewed mainly from wheat with only a small amount of soybean, this soy sauce is nearly amber in color and notably sweet. Hekinan, Aichi is said to be its birthplace, and it is prized for seasoning dishes — such as shiro-dashi — where a pale color matters.

Lineage
What it's made of
Nearly amber and pale in color, with a sweetness that stands out. Brewed mainly from wheat with only a small amount of soybean, it barely darkens a dish, making it the seasoning of choice when a recipe wants the ingredient's own color to show through, as in a clear shirodashi-based dish.
How it's made
Wheat forms the bulk of the koji, with just a touch of soybean added, and the mash ferments only briefly before pressing. Keeping the aging period short holds the color back from deepening, while preserving the sweetness and faint toastiness that comes from the wheat.
Why it took this shape
Hekinan, Aichi is said to be its birthplace — a town on Mikawa Bay well suited to both sea transport and brewing. Demand for a pale soy sauce is said to have grown out of Kyoto- and Kansai-style cooking, where dishes like shirodashi call for color to stay light rather than deepen.
Before you go
- Words about taste and cookingBroth types, spice levels, and noodle firmness — words you're often asked to choose when ordering.
- What to know if you have dietary restrictionsHow allergen labeling works, where fish-based dashi, pork, and alcohol turn up, and phrases for checking with staff.
- How Japanese seasoning tends to tasteWhy Japanese food can taste mild to some visitors, the role dashi and umami play as a flavor base, what soy sauce, miso, mirin, and vinegar each contribute, what "spicy" usually means, and adjusting flavor at the table.
Dishes in the same style
- Choshi shoyuOne of Kanto's leading soy sauce production areas, said to have been founded by merchants from Kishu in the early Edo period. The mild, humid climate — shaped by the meeting of the Kuroshio and Oyashio currents offshore — is said to suit the koji mold and yeast used in brewing, and the town's output helped feed Edo.
- Echigo misoA red, savory miso from Niigata, also called 'ukikoji miso' (floating-koji miso) because its polished whole-grain rice koji appears to float within the paste. Its style is said to vary across Niigata's Joetsu, Chuetsu, Kaetsu, and Sado districts, each shaped by local climate.

- Koikuchi shoyuThe most common soy sauce style, said to account for roughly 80% of national shipments. Made from roughly equal parts soybean and wheat, it carries a reddish color and a pronounced aroma, and serves as the everyday base seasoning nationwide.
- Saishikomi shoyuA rich soy sauce made by re-brewing already-finished raw soy sauce with a fresh batch of koji. Said to have been created in the mid-Edo period by a brewer in Yanai, Yamaguchi, who presented it to his lord — who reportedly praised it as 'kanro, kanro' (nectar, nectar), giving it the alternate name kanro shoyu.
Also from Aichi
- Funa MisoCrucian carp is simmered slowly with soybeans for around five hours, then finished in a sauce of red miso and coarse sugar. A freshwater fish dish of the Kiso rivers' lower basin, made with fatty winter carp simmered until the bones soften through.
- Gohei MochiFreshly cooked non-glutinous rice is pounded, pressed flat on a skewer, and grilled with a miso glaze. Said to have originated in the mountainous Chubu region, it's traditionally made the night before a festival praying for safety in mountain work.
- Aichi HakozushiVinegared rice is packed into a wooden frame, topped with shrimp, eel, shiitake, and egg arranged diagonally, and pressed. Placing toppings on the diagonal so everyone gets a fair share of each is said to be a feature of the Owari and western Mikawa style, made for celebrations.
- Hebo MeshiAdult and larval giant hornets are simmered sweet and savory, then folded into freshly cooked rice. Said to have served as a prized protein source across the mountains from Shinshu to Okumikawa, it's now more often served as a treat for guests.
- Iga ManjuSweet bean paste is wrapped in rice flour dough, then coated with dyed sticky rice grains. One account ties the name to the grains' resemblance to a chestnut's spiny husk, and in the western Mikawa region it's said to be offered to Hina dolls at the Doll Festival.
- Aichi Miso OdenA pot of sweet red miso sits in the center of the simmering pot, and daikon, tofu, and other ingredients simmered in dashi are dipped into it before eating. While soy-based Kanto-style oden spread in Edo, Aichi is said to have settled on dipping in soybean miso instead.
