Decoding Noritake Backstamps: A Collector's Guide

The underside of a Noritake plate tells a story as rich as the design on its face. For over a century, the Morimura Brothers (the founders of Noritake) used hundreds of different backstamps (or “marks”) to satisfy export laws, designate quality tiers, and brand their evolving product lines.

For collectors, learning to read these marks is the primary skill for dating a piece and determining its value. A “Nippon” vase from 1910 holds a completely different historical significance—and market value—than a mass-produced “Cook & Serve” plate from 1975.

This guide provides a chronological roadmap to identifying your Noritake china.

Before the brand was officially known as “Noritake” globally, their wares were marked “Nippon.”

In 1890, the United States passed the McKinley Tariff Act, which required all imported goods to be marked with their country of origin in English. Since the western name for the country was “Japan” but the Japanese called it “Nippon,” the company chose the latter.

• The Maple Leaf (1891–1915): One of the earliest and most desirable marks. It features a hand-painted or stamped maple leaf with “Hand Painted” and “Nippon” below it. These pieces are often delicate, highly decorative porcelain.
• The Rising Sun (1911–1921): Features a sun with rays radiating outward. This was used extensively on export wares.
• The “Maruki” Symbol (Komaru): The classic symbol of the Morimura clan. It looks like a tree or a spider leg design inside a circle. The character actually represents the “hardships” the company overcame.
  • Note: If a piece is marked “Nippon,” it almost certainly dates to before 1921.

Collector's Tip: Be wary of fake Nippon marks. Authentic Nippon marks are usually under the glaze. If the mark looks like a sticker or sits on top of the glaze and can be scratched off, it is likely a reproduction.

In 1921, the US government updated its import policies, requiring the country of origin to be listed in standard English (“Japan” instead of “Nippon”). This forced the company to change its stamps.

This is the most iconic mark associated with vintage Noritake.

• Design: The letter “M” (standing for Morimura) inside a floral wreath.
• Text: Usually reads “Noritake” above and “Hand Painted” or “Made in Japan” below.
• Color Coding:
  • Green: The most common color, used for general dinnerware exports.
  • Blue: Often indicates pieces destined for the US market specifically.
  • Magenta/Red: Sometimes reserved for higher-end decorative ware.
  • Gold: Typically found on the finest quality pieces.

Often found on hand-painted scenes (landscapes), this mark depicts a tree by a lake. It signifies the romantic artistic style of the 1920s and 30s.

World War II halted production. When the factory resumed operations after 1945, Japan was under Allied occupation.

From 1947 to 1952, US Customs required all goods imported from Japan to be marked “Made in Occupied Japan” or simply “Occupied Japan.”

• Collectibility: While the quality of the porcelain during this period was sometimes inconsistent due to material shortages, these marks are highly collectible for their historical specificity. The window of production was very short (less than 5 years).

After the occupation ended, the company rebranded to appeal to modern Western tastes. The “M” was gradually replaced by an “N”.

Similar to the pre-war mark, but the “M” was replaced by an “N” for Noritake. This signified the brand's establishment as a household name, independent of the Morimura family name.

You will often see marks with “RC” surrounded by olive branches.

• Meaning: This stood for “Royal Crockery” (later “Royal China”).
• Purpose: This was a specific line of high-quality china designed for export to India and Southeast Asia initially, and later to the US. It often features mid-century modern designs.

As Noritake moved into the modern era, the marks became more standardized and utilitarian.

• The Stylized “N”: A simple, bold letter “N” used in the 1970s and 80s.
• Pattern Names: Modern backstamps almost always include the name of the pattern (e.g., “Shenandoah,” “Rothschild”) and a 4-digit pattern number (e.g., “9776”). This makes identifying replacements on sites like Replacements.com much easier.
• Microwave/Dishwasher Safety: Contemporary marks will explicitly state “Dishwasher Safe” or “Microwave Safe.” If the mark does not say it, assume it is not.

Noritake produces both.

• If the mark says “Bone China,” it contains bone ash, making it translucent and stronger.
• If the mark simply says “Porcelain” or “China,” it is hard-paste porcelain.

Identifying a Noritake backstamp is like solving a small mystery. It tells you whether your cup witnessed the Roaring Twenties, the austere post-war reconstruction, or the dinner parties of the 1980s. When caring for your collection, always let the age determined by the backstamp dictate your maintenance routine—older marks generally mean strictly hand-washing.
