Gluten-Free Japanese Noodles
Here is more detail on the major types of naturally gluten-free Japanese noodles:
Soba
Soba is a thin, brown noodle made from buckwheat flour. It has an earthy, nutty flavor and chewy texture. Since it does not contain any wheat, soba is completely gluten-free.
Soba noodles are often served cold with a dipping sauce called tsuyu. They can also be featured in hot noodle soups and stir fries. Classic soba dishes include:
– Zaru Soba – Chilled soba with dipping sauce
– Kitsune Soba – Topped with sweet fried tofu
– Tanuki Soba – Topped with tempura crumbs
– Kamo Nanban Soba – Topped with duck and scallions
When purchasing soba noodles, be aware that some contain a small amount of wheat flour in addition to buckwheat. Check labels and ingredient lists to verify 100% buckwheat soba for a gluten-free option.
Shirataki
Shirataki noodles are made from the konjac yam. They are translucent, gelatinous noodles that are gluten-free, low calorie, and low carb. Shirataki noodles have little flavor on their own, so they easily absorb surrounding sauces and seasonings.
Since they have a rubbery, chewy texture, shirataki noodles work best in soups, hot pots, and stir fries. They require rinsing and brief boiling or pan-frying to reduce any funky odor. Popular shirataki dishes include:
– Oden – Various ingredients stewed in dashi broth
– Sukiyaki – Thinly sliced meat cooked with vegetables
– Yaki Udon – Pan-fried udon noodles and vegetables
Shirataki noodles can be used as a gluten-free substitute for ramen and udon in these dishes. Look for shirataki noodles made 100% from konjac flour to ensure gluten-free.
Harusame
Harusame translates to “spring rain” and refers to thin translucent noodles made from potato starch or mung bean starch. They have an elastic, gel-like texture and bland flavor.
Harusame noodles are commonly used in hot pots, stir fries, and chilled noodle dishes. They readily absorb surrounding flavors. Some popular harusame dishes are:
– Yakisoba – Stir-fried noodles with meat and vegetables
– Nabeyaki Udon – Udon noodle soup cooked in an earthenware pot
– Sōmen Salad – Chilled somen noodles with vegetables
When shopping for harusame noodles, check that they are made purely from potato or mung bean starch without any wheat-based ingredients. This makes them gluten-free.
Konyaku
Konyaku noodles are made from the konyaku yam. They have a jelly-like consistency and are translucent white in color. Konyaku noodles are gluten-free and low carb.
Since they have an ultra-chewy, gelatinous texture, konyaku noodles are best paired with saucy dishes. They are commonly used in:
– Oden – Dashi broth stew with ingredients like fish cakes, boiled eggs, and radish
– Sukiyaki – Thinly sliced beef cooked in sauce with veggies
– Mizore Nabe – Hot pot with salmon, tofu, and vegetables
Check ingredient lists when purchasing konyaku noodles to ensure they do not contain wheat or gluten ingredients. 100% konyaku noodles are gluten-free.
Finding Gluten-Free Japanese Noodles
When shopping for Japanese noodles, read labels carefully to identify gluten-free options. Also check for certification symbols like the Crossed Grain symbol which indicates gluten-free products. Some gluten-free Japanese noodle brands include:

Cellophane Noodles – Made from mung bean starch, these are common in somen salads.
