Enjoy Seasonal Fish from Waters Near Nagasaki in Luxurious Style

The biggest draw is the abundance of kaisendon and à la carte dishes that let you savor seasonal fish caught near Nagasaki.
Because toppings are purchased daily, they are always fresh and seasonal.
Among them, the three signature Tokusen Kaisendon bowls- “Megumi,” “Uomaru Don,” and “Uomaru Irodori Don”-are especially popular with both locals and tourists.
These specialties feature about 3-10 recommended toppings of the day, letting you enjoy vibrant visuals along with rich flavor.
They are so delicious that they feel packed with the blessings of Nagasaki’s sea, and they sometimes sell out later in the day.
Beyond these, the lineup also includes items such as “Asa no GOMA Don” and “Uomaru-Style Tamago Don,” offering a well-rounded selection you can choose from based on your preferences and mood.

High Satisfaction: Every Kaisendon Comes with Miso Soup, Grated Yam, and Pickles

In addition to the seafood’s freshness, another charm of Kaisendon Uomaru Asa is that you can enjoy the bowl in different ways until the last bite.
Every bowl comes not only with a special sesame sauce but also with miso soup, grated yam (yamaimo), and pickles, making each serving highly satisfying.
The special sesame sauce has a richly fragrant, toasty character that enhances the seafood’s umami.
The yamaimo is served separately in a tororo style; pour it over to round the flavors smoothly, or mix it in gradually to vary the taste with each topping-both are recommended.
A how-to-eat guide is available at each seat, and if you are unsure how to use the condiments, ask the staff and they will explain kindly.
You can also switch the miso soup to chawanmushi upon request, which is a nice touch for tailoring the meal to your liking.

2. Salmon & Ikura Parent-and-Child Donburi

If you want to fully savor salmon, a favorite sushi topping, go for the “Salmon & Ikura Parent-and-Child Donburi.”
Slices of salmon are beautifully arranged like petals across the bowl, with a generous scattering of ikura on top for a visually striking dish.
The instant you take a bite, the salmon’s sweet fattiness and the ikura’s saltiness harmonize perfectly, creating a delightful contrast of umami.
The ikura’s popping texture adds an accent that keeps your chopsticks moving.
It pairs wonderfully with a cold draft beer, so enjoying it with alcohol is also recommended.

3. Heaping Ikura Donburi

“Heaping Ikura Donburi” is a kaisendon where ikura takes center stage, covering the entire bowl.
Fresh roe purchased that day is marinated just right in a soy-based sauce so each bead retains a firm bounce-an item that exemplifies Kaisendon Uomaru Asa’s commitment to freshness.
The moderately salty ikura mixes with the sweetness of freshly cooked rice to deliver a simple yet highly satisfying flavor.
With every bite, the popping texture and rich taste of the ikura burst forth for a blissful moment.
It is recommended not only for ikura fans but also for anyone who wants to experience seafood umami in a straightforward way.

End Your Kaisendon with Dashi-Chazuke

Before you finish your kaisendon, order “dashi” (available at no extra charge) and end with chazuke.
The broth provided is Nagasaki’s specialty flying-fish (ago) dashi, notable for a rich yet light flavor.
Pouring this broth over the kaisendon is called “dashi-chazuke.”
When hot ago dashi is poured over raw seafood, the heat changes the toppings’ aroma, offering a gentle umami distinct from sashimi’s texture.
As a way to eat, it is common to order the dashi when about one-third of the bowl remains, then pour just enough to lightly soak the rice.
After that, adjust the intensity to your liking, checking the balance as you go.

Enjoy dashi-chazuke to finish.
