Kome-miso tanshoku karamiso (米みそ淡色辛みそ) — light-color salty rice miso — is by far the largest-volume miso category in Japan. Shinshū-miso (信州みそ), produced principally in Nagano Prefecture, is the canonical example: a salty, light-yellow rice miso fermented for 6–12 months and used as the everyday cooking miso in most of central and eastern Japan. Most of what overseas consumers know simply as 'miso paste' falls within this category.

What it is

Light-color salty rice miso is brewed from steamed soybeans, rice koji, and salt at standard ratios (typically 100% koji to soybean by weight, 11–13% salt). Fermentation runs 6–12 months at controlled temperature in modern industrial production, longer for traditional artisan producers.

The 'light color' (淡色) classification reflects controlled fermentation conditions that suppress excessive Maillard browning. The 'salty' (辛) classification reflects the standard salt level (11–13%) versus the lower 5–7% of amamiso.

Nagano Prefecture (Shinshū region) is the largest production center; Shinshū-miso accounts for roughly half of total Japanese miso production. Other light-salty rice misos are produced widely across central, eastern, and northern Japan.

Typical uses in Japanese products

Light-color salty rice miso is the standard cooking miso for most of Japan — used as the daily miso soup base, in marinades for grilled or simmered dishes, in dressings, and as a seasoning component in nimono and other savory preparations.

In awase-miso (blended miso) products, light-color salty rice miso is typically the principal component, often blended with mame miso (such as hatcho miso) for a balanced flavor profile.

For OEM, this category is the principal base for instant miso soup, dashi-iri miso (miso with built-in dashi), and most retort-grade miso seasoning components in prepared meals and convenience-food products.

Regulatory classification in Japan

Light-color salty rice miso is JAS-categorized as kome-miso, tanshoku, karami (rice miso, light color, salty) under the JAS standard for miso.

JAS distinguishes 米みそ (kome / rice), 麦みそ (mugi / barley), 豆みそ (mame / soybean-only), and 調合みそ (chōgō / blended) categories. Within kome-miso, JAS sub-categorizes by color (white / light / red) and salt level (sweet / medium / salty).

Allergens: soy must be declared. Wheat is not standard but some chōgō products may include wheat.

Regulatory classification in other markets

EU	Imported as fermented soybean paste. The standard product type for 'miso paste' in EU retail. Allergen labeling for soy required.
USA	Imported under FDA standard food procedures. The standard 'miso paste' category in US retail; corresponds to most generic 'miso' SKUs sold in US natural-foods and Asian-grocery channels.
China	Imported under GACC rules for fermented condiments.
Korea	Imported as fermented soybean paste; distinct from Korean doenjang.

FAQ for OEM buyers

Q. What's the difference between Shinshū-miso and 'light-color salty rice miso'?

Shinshū-miso is a regional name for the light-color salty rice miso produced in Nagano Prefecture (Shinshū region). It is the canonical example of the JAS tanshoku karamiso category, but the JAS classification is broader — light-color salty rice miso produced in other regions (Sendai-miso, etc., partially) belongs to the same JAS sub-category. Most generic 'miso paste' on retail shelves in Japan and overseas is from this JAS sub-category.

Q. Is dashi-iri miso (miso with built-in dashi) the same JAS category?

Dashi-iri miso (だし入りみそ) is a chōgō (調合 / blended) preparation that uses light-color salty rice miso as its base and incorporates dashi components (typically katsuobushi extract, kombu extract, or hydrolyzed bonito). It is JAS-classified separately from straight kome-miso. For retail convenience, dashi-iri miso is positioned as a one-step miso soup base.
