Are Noritake dishes dishwasher safe, or should they be washed by hand?

Dishwasher safety for Noritake also varies with pattern, age, and decoration. Noritake’s care and safety page lists general guidelines along with a long table of named patterns and whether they are dishwasher safe. Many casual modern collections, such as Colorwave, Colorscapes, ColorTex, ColorKraft, ColorStax, and Hammock, are marked “Yes” for dishwasher use. In that table, some formal patterns with metal bands are marked dishwasher safe but not microwave safe, while others are marked “No” for both dishwasher and microwave. For patterns purchased prior to about 1998 that do not appear online, Noritake advises hand washing until you can confirm with customer service. Detergent type and water hardness can influence wear on trim over time, so some collectors still prefer gentle hand washing for vintage or heavily gilded pieces even if the pattern appears on the dishwasher-safe list. For brand-new patterns, the product page is the quickest way to check.
