Dining Prelude

Exterior & Entrance

“Tsuruhachi” is located about a 2-minute walk from Karashimacho Station on the Kumamoto City Tram line.The restaurant sits on the second floor of the Fujimoto Building in the Shinshigai district;the building’s exterior is simple and understated, yetthe entrance carries a quiet, composed atmosphere.At the top of the stairs,a wooden sliding door with a distinctly Japanese sensibilitygreets visitors with a quiet sense of anticipation.

The Dining Space

The interior of “Tsuruhachi” is built around an L-shaped counter with nine seats.Guests can watch the chef’s craftsmanship up close across the counter, with freshly fried tempura served one piece at a time.The space carries a calm, distinctly Japanese atmosphere, where the warmth of wood and soft lighting come together in quiet harmony.It’s the ideal dining space for a special occasion, or simply for savoring an unhurried evening.

The Menu Experience

The backbone of the course is seasonal tempura built around ingredients from Kyushu and Kumamoto.
On this visit, the lineup centered on Kumamoto-grown kuruma prawn, conger pike eel (hamo), sillago, mantis shrimp, and hatoshi, alongside conger eel from Nagasaki and a selection of white fish.
Vegetables are also sourced exclusively from Kumamoto, featuring seasonal picks like new potatoes, round okra, red eggplant, beans, and baby corn.

On top of this, guests who wish can also order sashimi or additional tempura separately.
A platter of exceptionally fresh sashimi is one such option — a sign that Tsuruhachi’s culinary range extends well beyond tempura alone.

Toward the end of the course, for an additional ¥770, guests can choose a finishing dish from mini tencha, mini kakiage rice bowl, or a small bowl of rice. This mini rice bowl, topped with the fragrant crunch of freshly fried tempura, provides a satisfying final note to the meal.

Seated at the L-shaped counter directly facing the fryer, each dish is served with focused attention, one at a time, in a meal that feels genuinely alive with energy.
By honoring the classics with care while adding small touches of variation and freedom, the presentation carries a depth that leaves you wanting to return, not just once.

Starting Drink

The meal opens with a moment of pause over a cold draft beer.
Its fine, creamy foam and crisp, clean finish make for the perfect lead-in to the tempura course ahead.

Sitting at the counter, listening to the sizzle of frying, offers a pleasant moment to slow down and settle in.

The Dishes

Small Bowl

The course opens with a small bowl featuring asparagus and taro, combined with sea bream tsumire (fish balls).
The refreshing fragrance of kinome miso envelops the dish, while the freshness of the asparagus, the earthy sweetness of the taro, and the delicate umami of the sea bream each shine in their own way.
From the very first bite, a springlike fragrance unfolds — a bright, refreshing introduction that builds anticipation for what’s to come.

Kue (Grouper) and Purple Sea Urchin Sashimi

Tender kue (longtooth grouper) sashimi, paired with purple sea urchin.

The kue is soft with just the right amount of fat, its umami deepening with every chew.
The purple sea urchin carries a rich sweetness that fades cleanly, leaving a pure, refined impression.

Neither element is overworked — the character of each ingredient is left to speak quietly for itself.
A dish that gently resets the palate as the meal moves toward the tempura ahead.

 

Amakusa Kuruma Prawn Head

The tempura course opens with the head of an Amakusa kuruma prawn.

The moment the freshly fried piece is set down, a gentle fragrance rises from the shell — the toastiness of the oil mingling with the faintly sweet aroma of the prawn, impossible not to smile at.

One bite delivers a crisp crunch, with the aroma bursting through the mouth all at once.
It’s never overly toasted, striking an exquisite balance that lets the prawn’s own natural flavor come through clearly.

Far from just a first course, it’s an opening that leaves you thinking, “I can’t wait to see what’s next.”

Amakusa Kuruma Prawn (Body)

Next came the body of the Amakusa kuruma prawn.

Its translucent white flesh, lightly coated in batter, arrives fresh from the fryer.
In contrast to the head, the body has a springy, plump bite the moment you sink your teeth in, with the prawn’s sweetness spreading gently through the mouth.

The batter is remarkably thin, with none of the heaviness oil can bring.
The quiet transition from the shell’s aroma into a gentle sweetness is beautifully done — it’s remarkable how much character a single ingredient can express.

Amakusa Sillago

Amakusa sillago is a fish with fine-textured flesh and a refined sweetness.
To showcase that delicacy, the batter is kept extremely thin, resulting in a light, airy fry.
The moment you bite in, a soft sweetness unfolds, followed by a clean release of ocean fragrance.

With no trace of oiliness whatsoever, this dish let the fish’s pure, natural umami shine through entirely on its own.

Kumamoto Round Okra

Next came round okra from Kumamoto.
A heirloom variety found in parts of southern Kyushu, distinguished by its round cross-section, tender texture, and notably mild sliminess.

Fried whole in a light batter, it’s served sliced down the middle at the table.
The beauty of that cross-section is the first thing to catch the eye.

Taking a bite reveals a gentle warmth alongside a subtle green freshness and mild sweetness, with the pleasant pop of the seeds adding a nice textural touch.
A dish that delivers the natural quality of the ingredient exactly as it is — vegetable tempura at its finest.

Kumamoto Eggplant (with Mustard)

A striking Kumamoto-grown eggplant, its vivid purple skin and plump flesh immediately catching the eye.
Before frying, we were asked, “Would you like some mustard added?” — an offer we happily accepted.

It arrived cut down the middle, its cross-section beautifully presented.
The moisture sealed within the batter retains its heat, releasing a gentle waft of steam as chopsticks break through.

Biting in reveals melting, sweet flesh alongside a gently savory, dashi-like umami, with the mustard adding a wonderfully subtle kick.
Following the chef’s suggestion, a few drops of soy sauce brought out the sweetness beautifully — a genuinely surprising combination.

A dish where the heat control, seasoning, and presentation were all executed with real care.

Ariake Sea Shako Mantis Shrimp

Shako (a type of mantis shrimp) caught in the Ariake Sea, fried whole, shell and all.

Its lightly battered, vivid red form has a striking presence. One bite delivers the toasty aroma of the shell, followed immediately by the rich umami of the roe and tomalley flooding out from the head.

The tomalley is deep in flavor without any harshness, while the roe adds a sticky richness, together lending the dish a bold, oceanic character.
The body meat is wonderfully soft, offering a pleasant contrast against the crisp, fragrant shell.

A dish truly meant to be eaten whole — striking in both impact and satisfaction.

Kumamoto “Nankai Midori” Green Peas

Mashed once, passed through a sieve to a smooth paste, then reformed into a ball and fried.

The plump, battered orb is charmingly round, and biting in releases a burst of hot, vividly green fragrance.
The pea’s own sweetness and hearty umami are concentrated within, conveying the raw power of the ingredient itself.

Hatoshi

Next came hatoshi, a dish known as a Nagasaki regional specialty.
Fluffy shrimp paste is sandwiched between slices of bread and carefully fried.

What’s notable is the chef’s technique of not serving it immediately after frying, instead letting it rest until the oil has fully drained.
Thanks to this, the batter stays light and crisp, letting the toasty aroma of the bread and the fluffy softness of the shrimp paste truly shine.

Biting in reveals a crisp exterior giving way to a juicy interior. Remarkably light, with none of the heaviness oil can bring.
A beautifully executed dish where the ingredients, the oil, and even the resting time itself are all carefully calculated.

Julienned Mountain Yam and Junsai

Junsai (water shield) and julienned mountain yam sit in a glass-clear dashi.
The gentle, gelatinous texture of the junsai and the crisp bite of the mountain yam play off each other quietly.

Taking a bite brings a cooling freshness with a faint viscosity, leaving behind the vivid, watery character of a true summer dish.
Understated, but a quiet, tranquil dish that mirrors the coolness of its ingredients directly in the bowl.

Kumamoto Ueki-machi Baby Corn

Baby corn, silk and all, sourced from Ueki-machi in Kumamoto.
Fried whole, its toasty batter combines with the juicy freshness of the young kernels to bring out corn’s natural sweetness to the fullest.
Even the silk is carefully fried, adding an extra layer of light, crisp texture that’s a pleasure on its own.

The chef cuts it into easy-to-eat pieces before serving, a thoughtful touch that lets you enjoy it while the heat is still fresh from the fryer.

Amakusa Conger Pike Eel (Hamo)

Amakusa hamo encases soft, fluffy flesh within its batter, and with each bite, a gentle sweetness of fat slowly unfolds.
A finishing touch of salt and green yuzu sharpens that umami, leaving a refreshing finish behind.
Light despite the oil, it made for a wonderfully summery dish.

Amakusa New Potato × Squid Ink Shiokara Butter

Fragrant and fluffy, this dish stars new potatoes from Amakusa.
These potatoes are, remarkably, slow-cooked for about an hour before being fried into tempura.

Moist within, lightly crisp outside — this dish, which lets the potato’s natural sweetness shine, is served alongside a strikingly bold squid-ink shiokara butter.

Silky butter meets the umami of shiokara and the deep richness of squid ink.
Dipped and eaten together with the potato, the sweetness, salinity, and richness merge in a way that draws out an involuntary groan of delight.

Honestly, this butter alone could carry an entire drink — a genuinely dangerous, unforgettable combination.

Tsushima Conger Eel

Closing out the tempura course is conger eel from Tsushima.

The chef cuts the freshly fried piece right in front of you.
In that instant, a wisp of steam and fragrance rises up — impossible not to catch your breath.

The batter is exceptionally light, the flesh within wonderfully soft.
The fat content is perfectly judged, its umami unfolding gently even without any condiments.

We were recommended to try it with soy sauce and lemon.
A touch of soy sauce brings out its sweetness beautifully, while a squeeze of lemon offers a refreshingly clean alternative.

A flawless dish right to the very end — a fitting closer to the tempura course.

Kumamoto Rock Oyster

Served between courses of tempura, this Kumamoto rock oyster made a striking appearance.

Plump and generously sized, its weight is immediately noticeable the moment it’s lifted with chopsticks.
One bite delivers a rich creaminess and mineral depth that instantly floods the mouth with the essence of the sea.

A mellow sweetness, a touch of salinity, and a lingering finish that stays with you.
Seasoning is kept to an absolute minimum, letting the raw power of the ingredient itself come through directly.

A completely different register of oceanic flavor from the tempura, adding real depth to the arc of the entire course.

Closing Tendon (Small)

To finish the course, I chose the small tendon (tempura rice bowl).

A compact bowl of rice topped lightly with kakiage-centered tempura, drizzled with a light sweet-savory sauce.
With no heaviness from the oil whatsoever, the crisp batter pairs beautifully with the rice.

Taking a bite releases the fragrant sauce alongside the aroma of the tempura, offering a satisfying close to the entire course.
The rice is cooked just right, a final sign of the meticulous care carried through to the very end.

A modest but memorable bowl that lingers pleasantly after the meal.

Dessert & Finale

Kumamoto Aso Pesticide-Free Sweet Potato Tempura × Brandy

To close the meal, a slightly unexpected touch: a dessert-style tempura made from pesticide-free sweet potato grown in Aso, Kumamoto.

Fried skin-on, the sweet potato is crisp outside and richly, densely sweet within.
The heat control is exquisite, with the potato’s natural syrup gently seeping through.

Accompanying it is a splash of fragrant brandy.
A small drizzle adds depth and a glossy richness to the sweetness, instantly transforming it into a decidedly adult dessert.

Not just a fitting way to close the meal, it carries a lingering finish reminiscent of a digestif.
A composition that stays true, right to the end, to a theme of frying and fragrance.

Final Thoughts

Tucked away on the second floor of a mixed-use building in Kumamoto’s Shinshigai district, this is a nine-seat tempura specialist.

Centered on ingredients from Amakusa and Aso, the style of serving each piece freshly fried, one at a time, carries the steady confidence of a long-established establishment.
The tempura crafted by the third-generation chef leaves nothing to waste in its heat control, aroma, and presentation, conveying a quiet yet unshakeable confidence.

What stood out most was not just his ability to draw out each ingredient’s natural character, but his willingness to actively pursue new forms of expression.
From new potatoes paired with squid-ink shiokara butter to sweet potato tempura enjoyed with a splash of brandy, the breadth of his creative imagination stands out.

The beauty of pacing, and the live, unfolding sense of watching each dish come together right before you, are part of the charm here too — this isn’t just a meal, but an experience that stays with you.
A special stretch of time built on Kumamoto’s local terroir, layered technique, and a flexible creative spirit.
