Exclusive Partnership & Factory Report

Developmental Power to Subdue Monsters Over 400kg.
A Visit to the Gouki Workshop in Chigasaki, Kanagawa, and the Start of Limited Rod Orders.

The world of an overwhelming MAX DRAG of 40kg. We introduce the full scope of super monster-compatible rods that decide the battle in 20 minutes, made possible by integrated in-house production.

Hello! Recently, thanks to a wonderful connection, I had the pleasure of a long visit to "Gouki," which has its workshop in Chigasaki City, Kanagawa Prefecture.
The room I was guided to was filled with sample rods nearing completion, and I was able to hear many valuable and in-depth stories about the現場 (genba - site/field) and development.

Among them, I received various proposals regarding "tuna-related rods," which I've been most keenly interested in lately, and I even made an unreasonable request for a special prototype sample.
I heard that in harsh overseas tests, they have already caught numerous fish over 400kg, and in Japan, they have repeatedly conducted thorough tests against fish over 300kg in the extremely fast-current Oshima area. Mr. Kaiken casually mentioned, "Even 300kg class fish can be landed in 20 minutes."

I gasped when I saw the specifications presented. MAX DRAG 40kg!!!
I involuntarily blurted out, "Seriously... is that even possible...?" The overwhelming development capability that makes other companies take notice. The strength of integrated in-house production carried out in the Shonan Chigasaki factory. The unfathomable depth of tuna fishing. And the genuine technical prowess cultivated and accumulated over many years through various types of fishing. I can't possibly describe it all in a blog post, but I heard shocking stories that gave me goosebumps all over after a long time.

The 20-Min Monster Tuner / Easy Catch Design that Becomes One with the Captain

And this time, under the full supervision of Gouki, we will be accepting limited orders for a "20-minute fight tuna rod" with special specifications as an Amberjack custom model!

Of course, our utmost commitment is to the robust power blank that slowly brings in monster-sized fish with just the rod's leverage, and the exquisite balance design that allows you to work in sync with the captain for an easy catch. This is a super monster-compatible rod with maximum specifications, unlike anything from other manufacturers.

The practical MAX DRAG is 40kg, but I believe very few anglers can apply more than 30kg of drag during an actual fight. However, by leaving such a "power advantage" in the blank as a margin, the lifting performance of the rod itself is significantly enhanced, greatly contributing to reducing angler fatigue during long, arduous battles. This is a 100% pure, fully handmade rod produced consistently at Gouki's factory. For inquiries regarding orders and specifications, please feel free to contact our official LINE.

🚨 Latest Information (Important Notice Regarding Delivery Times)

Thank you very much for your many inquiries. For models that are not in stock, delivery is expected to take 4 to 6 months after ordering.
While there is a considerable backlog at Gouki's workshop, causing delays, we are confident that we can provide you with the best rods that will undoubtedly satisfy you, so please look forward to their arrival!

The Lineup / The Full Scope of Super Monster-Compatible Models

We are excited to introduce all 4 models of our ultimate lineup, which you can choose from according to your boat size and fighting style. These are customized based on Gouki's strongest and latest regular model, the Blue Magia MH blanks.

GOUKI MASSIMO 777 max power ver.
159,000 yen (excl. tax)
Casting model / Overall length 237cm / Grip joint 2-piece / Target: Over 300kg

This is a long-length model that thoroughly pursues the balance between "long-distance casting performance" for targeting boils and "easy catch" after hooking in large recreational fishing boats over 40 feet. For those considering replacing their monster casting rod, this is a rod I would unhesitatingly recommend!

GOUKI MASSIMO 666 max power ver.
159,000 yen (excl. tax)
Casting model / Overall length 203cm / Grip joint 2-piece / Target: Over 300kg

This model demonstrates exceptional lifting performance on boats where maneuverability is required, up to 30 feet. Designed specifically to pursue an aggressive fight that gives no initiative to the fish, allowing anglers even without great arm strength to tackle monsters with minimal physical exertion.

GOUKI SOTTOMARINO 666 max power ver.
159,000 yen (excl. tax)
Bait jigging model / Overall length 203cm / Grip joint 2-piece / Target: Over 300kg

Created with the concept of jigging and fighting using a Black Magic gimbal. This model has a meticulously set length to allow the angler to maintain control during power lifts and turns in fall-focused tuna jigging. It features an exquisite blank that bends slowly from tip to butt without being too short, too long, or too stiff. This is a special model designed to catch monsters, pursuing balance in gimbal fights.

GOUKI TONNO MAESTRO 555 max power ver.
159,000 yen (excl. tax)
Standing bait model / Overall length 169cm / 1-piece / Target: Bluefin tuna over 300kg

Afterword: The Story of GOUKI / From Chigasaki to the World. The Madness and Passion of Gouki

Through this workshop visit, I was able to directly experience the "philosophy" flowing deep within the Gouki brand. Gouki Co., Ltd. has its factory in Chigasaki City, Kanagawa Prefecture. The representative, Mr. Tsuyoshi Tsurumaki, and the fishing advisor, Mr. Kaiken, are undoubtedly "anglers to the core" before being rod builders.

Why can Gouki rods land monsters over 400kg in just 20 minutes? It's not simply because the carbon or glass blanks are made stiffer and thicker. In big game live bait fishing and bluefin tuna casting, there exists a golden ratio of "bending fulcrum" and "tenacity" that provides immense lifting power and minimizes angler burden. This ratio is derived not from theoretical speculation but from confronting giant fish in the harsh environment of the sea. This is made possible by the millimeter-precise taper adjustments and proprietary manufacturing methods that maximize the potential of glass solids, achievable only by a factory with integrated in-house production.

The Ultimate Tools Born from "Uncompromising Fieldwork"

"We will never release a rod that we are not satisfied with."

As if to prove this belief, Gouki's workshop was lined with a vast number of test blanks. Their straightforward and passionate attitude is to genuinely enjoy and cover all kinds of fishing throughout the seasons, including targeting super big game, sea bream with drift fishing, hairtail with tenya rigs, and rock fishing for rockfish, while also relentlessly pursuing extreme targets. This obsessive dedication of "being an angler and a proud craftsman" beyond just a manufacturing company is the biggest reason why the Gouki brand has been deeply loved by many heavy anglers for so long.

Gouki rods, where functional beauty and obsessive strength coexist. They are sure to become the "best partner" for anglers ready to push their limits. At Amberjack, we strongly wish to continue delivering these tools, imbued with their spirit, directly to everyone.

At Amberjack, we will continue to provide intensive field reports by working with pioneers, aiming to deliver the real current situation of the tuna scene to our customers as much as possible. Writing so much about intense tuna fishing has made me feel like going for a leisurely utase sea bream fishing trip again (lol).
