Fishing aside, one of my favorite reasons for visiting Japan as a kid was to dig for clams at low tide. For a 6 year old, there are few things more exciting than sinking your hands into a cool slurry of sand and coming up with a handful of clams that would later make it into a bowl of miso soup for breakfast.
Those clams are known as Asari in Japan, but thanks to the popularity of Japanese oysters, they were introduced to the West Coast of the US, and are commonly known as Manila clams in grocery stores. They have a wonderful briny flavor different from other varieties of clams, which makes for a soup that's a refreshing change from your usual bonito and konbu-based miso soup.
It's also easier to make than most miso soups because there's no need to make dashi first. You start with water, and the hard-working mollusks turn it into a delicate broth. Miso, which is a fermented soybean paste, seasons the broth while packing it full of umami. Mushrooms add more flavor and texture, but you can really add just about anything you want (or leave them out all-together).

📖 Recipe
Units
Ingredients
- 200 grams Manila clams (a.k.a. Asari clams)
- 2 cups water
- ½ package Japanese mushrooms (such as shimeji, enoki or nameko)
- 1 ½ tablespoons miso (to taste)
- 1 scallion (chopped)
Instructions
- The day before you plan to make your miso soup, add the 200 grams Manila clams and 1 teaspoon of salt to a bowl and add just enough water to cover the clams. This will make the clams open and release any sand they contain. The next day, rinse the clams
- Add the ½ package Japanese mushrooms, clams and 2 cups water½ package to a small saucepan and bring to a boil. Cook until the clams open (about 1-2 minutes).
- Turn the heat down and add the 1 ½ tablespoons miso, dissolving the paste in a ladle filled with a little soup first to avoid clumps. Because different types of miso vary in salinity, taste the soup and adjust the miso to taste.
- Finish by adding the 1 scallion and serve immediately.

can we substitute some of the water with sake?
Elleanor Eng says
Decided to give it a go, and it had a lovely homey taste. I'm used to the more aggressive flavors of Cambodian food, so I added kombu, bonito, and soy sauce. I just found your site, and I'm really excited to try all the recipes.
Marc Matsumoto says
Thanks Paganmist! It's my goal to make the preparation of tasty wholesome food accessible and fun for people of all skill levels, so I'm glad to hear you've found it helpful!

Marc, I want to say thank you and express my appreciation for this beautiful site and these amazing recipes. As weird as it sounds, I feel like this site is actually a gift to the world. It's so obvious that everything here is presented with love and thought.
I'm transitioning to a healthier way of eating, and finding healthy recipes that don't make me want to run and grab a burger isn't easy. Your site is helping with that, though.
Thank you for sharing your artistic and culinary efforts with us, as well as your clear love of good food.

Hi Camila, hatcho miso is used for miso soup in certain parts of Japan, but it can have a rather strong flavor. What miso you use depends mostly on the region of Japan you're in. Personally I like yellow miso made with soybeans and rice (as opposed to soybeans and wheat) as the kind made with rice tends to be sweeter.
camila says
Hi Marc! what variety of miso paste do you use for miso soup? i bought hatcho and it didn't taste right, then I saw in the comments of another recipe that its not suitable for soup. which one of the other types (rice, barley, brown rice) is the best for a regular miso soup? also, is it possible to buy stock that is made with kmobu, bonito and whatever other fish stock ready? also, is most bonito out there full of msg or not?
thanks!
Marc Matsumoto says
Nope, no tomatoes though that might make for a novel miso soup:-) Just Asari clams and Japanese mushrooms (nameko).
pansy says
the pic on asari miso soup looks good. is there tomato in it as I saw something reddish?
Raphael Clancy says
My local market usually has Manila clams and Enoki mushrooms. I decided to try this as a nice warm up after a day hiking in the mountains with some friends. But, when I hit the market, they had neither Asari nor Enoki. So, I made it with little neck clams and cremini mushrooms. I figured that the little necks would have a milder flavor, so I bulked up the stock with a little dried bonito and a piece of kombu, and it turned out great! Thanks so much for sharing the recipe.

Looks Amazing
Marc Matsumoto says
The water to soak should be cold.
Alice says
Should the water be cold, warm or hot when you put the clams in salted water to get rid of the sand?
essay help says
very cool pst! thanks alot for sharing!
Marc Matsumoto says
Nope, but you do want to soak them in salt water for a bit to get them to release any sand they may contain.
Lagolden says
Do you scrub the outside of the clams first? I have never cooked them so wonder?
Marc Matsumoto says
There's a bunch of seafood suppliers online that aren't crazy expensive, try looking around online. https://www.ilovebluesea.com/ has Manila clams for $8.88 per pound.
sophist_roland says
This was always my favorite miso soup to get served when I was living in Tokyo. Wish the midwest got some of those clams. I can't even get enoki mushrooms without paying an arm and a leg for them. Do you know of any easy to get substitutes for the manila/asari clams?
Marc Matsumoto says
Nope, the shells, don't impart any flavor or nutrients as far as I'm aware of. You could certainly remove the meat and serve just the meat in the soup if you like, but it's traditionally served with the shells.
OKay says
do the shells impart much flavor? are they nutritious?
cjbollinger says
This looks simple, beautiful and very tasty. I'll have to opt for whatever clams are available at our little 'eh' market, but definitely worth a go.
Darren Tran says
Sounds great... need to try this!

Clam-flavoured broth is delicious! That first photo is really calling out to me...
