If you love both Italian and Japanese cuisines, Japanese-Style Seafood Spaghetti is a must-try. This unique fusion dish combines the rich, savory flavors of seafood with the light, delicate touches of Japanese ingredients, creating a truly unforgettable pasta experience. It’s a perfect balance of umami and freshness, with seafood taking center stage in a light, flavorful sauce.
At the heart of this dish are the fresh, tender seafood ingredients. You can use a variety of seafood such as shrimp, mussels, scallops, and squid, or whatever is in season or available. These ingredients are sautéed to perfection, bringing out their natural sweetness and brininess.
The magic of this Japanese-style spaghetti lies in its sauce. Instead of using a heavy tomato-based sauce or a traditional Italian garlic and olive oil dressing, this dish uses a combination of soy sauce, mirin (a sweet rice wine), and a touch of sake. These ingredients create a light but flavorful sauce that enhances the seafood without overpowering it. A dash of sesame oil adds an extra layer of depth, and a little grated ginger provides a subtle zing, brightening the overall dish.
The spaghetti itself is cooked al dente, and then tossed with the seafood and the umami-rich sauce. The noodles absorb the sauce, making each bite flavorful and satisfying. To elevate the dish, a sprinkle of toasted sesame seeds, sliced scallions, and a touch of chili flakes can be added for extra texture and a hint of heat.
This Japanese-style seafood spaghetti is perfect for a light dinner or a special meal that’s sure to impress. It offers a beautiful combination of flavors and textures — the sweetness of the seafood, the depth of the soy-based sauce, and the chewy pasta that ties it all together.
In summary, Japanese-Style Seafood Spaghetti is a delightful fusion dish that brings the best of both worlds. It’s simple, flavorful, and packed with fresh seafood and umami-rich ingredients, offering a perfect balance of Italian comfort and Japanese elegance.

Yummm! My family devoured this. The flavors were on point. Definitely gonna make this again! ❤️
I was skeptical at first but this turned out better than I thought. Yum!
I totally agree! This dish was a surprise hit in my house too. Can’t believe how easy it was!
Did I miss something? Why so many different seafoods? My dad thinks it’s weird.
Spaghetti took longer to cook than the time sayed. I totally messed it up 😩
I followed the recipe but it turned out a bit bland. Maybe I needed more spices?
You might want to try adding some chili flakes or more soy sauce next time! Spices can really amp up the flavor!
Tasty AF! Will def make again! A+ recipe!
Super delicious! I didn’t have some ingredients, so I just used what I had, still turned out great. Thnx!
WOW!! This is the best spaghetti I ever made!! 🦐🍝
Best? Really? I mean, it’s good, but I think it’s just the same as regular spaghetti. 😂
That’s awesome to hear! I love seafood spaghetti. What did you think of the soy sauce with the seafood?
I tried it but I don’t like spaghetti with seafood… maybe its just me.
Seasfood? 🤮 I prefer my spaghetti with meatballs. But to each their own, I suppose.
My kids hated it. They only eat plain pasta. 🤷♂️
I’m sorry to hear that! Kids can be picky eaters. Maybe try a plain version next time?
This was surprisingly good! The flavors were just right.
I don’t know about this… seafood in spaghetti? Sounds weird. But my friend loved it, so who knows?
I tried this recipe but didn’t have soy sauce, so I used BBQ sauce. It was still kinda good, but not what I expected.
Best seafood pasta I ever made! Thanks for sharing this
You’re welcome! I’m so glad you enjoyed it! 😍
Soo easy to make! I skipped the sugar tho.
Really good but I think too much garlic. Y’all can skip it
I disagree! The garlic is what makes it flavorful. You can’t skip that!
This seafood spaghetti is just amazing! The flavors are on point. Love it!
Wow, this is a great twist on spaghetti! I added some chili flakes for a kick and it was delish!
Sounds amazing! I love the idea of adding chili flakes. Definitely gonna try this recipe.
Way too salty for my taste, can’t really taste the seafood.
Doesn’t taste like the stuff I had in Japan but still pretty good.
I totally get what you mean! I went to Japan and had the real deal, but this recipe is still a solid choice! Just needs a bit more spice for my taste.
Nah, it’s not the same! You gotta have the real Japanese seafood spaghetti to compare. This one feels kinda off, ya know?
Um, is spaghetti really Japanese? I thought they use noodles not pasta. 🤔
