Little Jack Co., Ltd. (リトルジャック株式会社, Little Jack) is a Japanese fishing-tackle manufacturer best known for its highly realistic hard lures and metal jigs. The company specialises in products designed to imitate the appearance, proportions, movement and behaviour of natural baitfish. Headquartered in Fukuoka, Japan, Little Jack is led by designer and CEO Yoshitake Matsuo (松尾尚武), who is credited with designing all of the brand’s lures.1

Established in 2001, the company has grown from a domestic lure maker into an internationally distributed fishing brand. As of 2026, Little Jack reports that its products are carried by approximately 1,700 retail stores in Japan through 45 major domestic wholesalers and chain stores. The company conducts business in 64 countries, including Singapore, where it maintains an exclusive distribution agreement.2

Little Jack was founded in 2001 in Fukuoka, on Japan’s Kyushu island. Its core business activities encompass the manufacture and sale of fishing-related products, OEM manufacturing, and the production of moulds and related tooling.3

From its inception, the company differentiated itself through a strong emphasis on realistic lure design. Rather than treating aesthetics as merely cosmetic, Little Jack’s design philosophy examines the relationship between a lure’s shape, volume, thickness, swimming action, sinking behaviour, sound and the manner in which predatory fish perceive prey underwater. The company describes this approach as a pursuit of “real” moulding, noting that it has spent nearly two decades developing lures centred on realistic form and behaviour.4

Over time, Little Jack expanded its catalogue beyond conventional minnow-style lures to include sinking pencils, vibration lures, blades, poppers, metal jigs, light-game lures, soft baits, squid jigs and other specialist tackle.5

Realism is the defining characteristic of Little Jack products. However, the company’s concept of realism extends beyond visual resemblance to fish. According to its product philosophy, an effective artificial bait must reproduce multiple characteristics that make real prey convincing to a predator. These factors include:

• Body profile and silhouette
• Three-dimensional volume
• Body thickness
• Natural swimming action
• Sinking speed and trajectory
• Flashing characteristics
• Sound
• Landing and water-entry behaviour
• Movement under different retrieve speeds
• The appearance of the lure from the fish’s underwater viewing angle

Little Jack posits that predators perceive a lure’s overall volume and shape rather than merely its length. Consequently, the company seeks to reproduce the physical impression of real prey rather than simply producing an object of correct dimensions.6 This distinction positions Little Jack as an engineering and performance brand built around realism, rather than one whose realism is intended primarily for collectors or visual appeal.

Yoshitake Matsuo is the central figure behind Little Jack’s lure development. Serving as CEO, he is credited by the company with designing its entire lure range.7 His influence provides the brand with a consistent design identity; rather than employing numerous unrelated designers with differing philosophies, Little Jack’s catalogue has historically been strongly associated with Matsuo’s approach to realistic lure construction. This has established a recognisable aesthetic characterised by extremely detailed fish profiles, unconventional body geometry, realistic finishes and carefully engineered actions.

Little Jack’s catalogue covers a broad range of lure types. Its official listings currently include the following categories:8

Minnows

Minnow lures form one of the most recognisable segments of the Little Jack range. They are designed around realistic baitfish shapes and are intended to imitate the appearance and swimming behaviour of naturally occurring prey.

Sinking pencils

The company produces a variety of sinking pencil lures, a category popular in Japanese saltwater fishing. These lures are capable of covering substantial distances and are designed to imitate fleeing or injured baitfish through controlled sinking and retrieve actions. The SAYORIS series is a notable example, taking design inspiration from the Japanese halfbeak (sayori) and emphasising an unusually realistic, slender baitfish silhouette.9

Metal jigs

Metal jigs are a significant component of the brand’s international identity. The Metal Adict family is particularly associated with Little Jack, combining the casting distance and density of conventional metal jigs with an unusually detailed baitfish appearance. These products are intended for applications including shore jigging and other forms of saltwater lure fishing, and independent descriptions frequently identify Metal Adict as one of the brand’s flagship series.10

Vibration and blade lures

Little Jack manufactures vibration and blade-style lures designed to generate strong underwater vibration and flash. These products are particularly useful when anglers need to attract fish from a distance or target deeper sections of the water column.

Poppers and swishers

The company produces surface lures intended to attract predatory fish through combinations of splashing, popping, sound and surface movement. The Bilhouette model, for example, is designed to combine popper-style action with diving-pencil behaviour and is offered in 135 mm and 160 mm sizes.7

Light-game lures

Little Jack offers products aimed at light-game fishing, where relatively small lures are used to target species feeding on small bait. AMEZAIKU JP, for instance, is designed around the micro-bait pattern. Available in 35 mm, 45 mm and 55 mm sizes, it can be used either independently as a sinking pencil or as a trailer-style bait.8

Squid-fishing products

The company has expanded into squid fishing with products that utilise fish-like swimming actions rather than relying exclusively on the conventional movements of Japanese egi-style squid jigs. The HUGGOS was developed around S-shaped and S-slide movements intended to imitate a fleeing baitfish and trigger predatory behaviour in squid.11

Specialised freshwater products

Although strongly associated with saltwater fishing, Little Jack also develops specialised freshwater products. KyUryUo is a highly realistic lure designed specifically for ayu (sweetfish) fishing. It combines a hard body with soft-material fins and uses a two-position line-eye system to alter its action and vibration.10

Key product families associated with Little Jack include:

The full catalogue is considerably larger than these examples, encompassing minnows, sinking pencils, vibrations, blades, light-game lures, soft baits, spoons, squid jigs and trolling products.12

Little Jack’s primary point of differentiation is its attempt to combine Japanese lure craftsmanship with biological imitation. While conventional lures often optimise primarily for casting distance, action, durability and colour, Little Jack adds an additional layer of consideration: how prey actually looks and behaves from the predator’s perspective.

Consequently, its products frequently feature unusually elaborate body shapes and details. The company emphasises that realism includes not only appearance but also how a lure sinks, moves, lands on the water, flashes and behaves when retrieved.13 This makes Little Jack particularly recognisable among Japanese lure brands, as its products often resemble small manufactured fish specimens rather than generic artificial lures.

Little Jack combines detailed moulded bodies with different material technologies depending on the specific lure. For example, AMEZAIKU JP uses a polycarbonate resin body and through-wire construction, while its movable hook arrangement allows anglers to change hook configurations.8 The newer KyUryUo demonstrates another approach, combining a rigid body with soft-material fins to create subtle vibration and movement when subjected to current.14 This illustrates that the company does not treat realism as synonymous with a single manufacturing method, instead using whatever construction is appropriate to reproduce the desired behaviour.

Although Little Jack is a Japanese company, its market has become increasingly international. According to dealer information, as of 2026 the company conducts business in 64 countries. It also reports approximately 1,700 Japanese retail outlets and relationships with 45 major Japanese wholesalers and chain stores.15

Its international distribution network includes markets across East and Southeast Asia, Australia and New Zealand, Europe, the Middle East, North America, South America and Africa. Singapore is specifically listed among the countries with which Little Jack has an exclusive distribution agreement.16

Little Jack’s identity can be summarised in four key concepts:

1. Japanese design: The company is based in Fukuoka and its product development is strongly associated with Japanese lure-making culture.
2. Extreme realism: Realistic form and silhouette are fundamental to the brand’s product philosophy.
3. Action as well as appearance: The goal is not merely to create an attractive replica, but to reproduce the movements and physical cues that cause predators to interpret prey as believable.
4. Specialised innovation: Little Jack frequently creates unusual solutions for specific fishing situations rather than simply reproducing established lure categories.

Today, Little Jack occupies a distinctive niche within the Japanese fishing-tackle industry. It is particularly recognisable to anglers interested in saltwater lure fishing, shore casting, jigging and realistic baitfish imitations. Its international profile has grown alongside its product range, while the company has retained its original emphasis on realistic lure design. The brand’s current catalogue demonstrates that this philosophy continues to be extended into newer areas such as micro-bait fishing, squid fishing, topwater fishing and specialised freshwater applications.17
