STUDIO OCEAN MARK PREMIUM HOOK SEIGI 23 HUTOZI 30F

The Ultimate Slow Pitch Jigging Hook for Greater Amberjack, Yellowtail Kingfish, Bluefish and Tuna.

Engineered for Slow Pitch Jigging (SPJ) targeting powerful pelagics, the SEIGI 23 Hutozi (Futoji / Thick Wire) 30F is Studio Ocean Mark’s specialized answer to the unique demands of hard-fighting pelagic fish.

Developed in close collaboration with renowned SPJ angler Yasuo Nishimoto.

Size #23 Thick Wire (Hutozi) is ideal for:

•  Yellowtail / Amberjack over 10 kg

•  Tuna in the 20–30 kg class

When the hook finds the hard “kannuki” (jaw hinge) area, it will hold fish significantly larger than the recommended range.

Key Hook Features

•  Long shank – Creates powerful leverage for superior penetration

•  Round wire shaft – Minimizes flesh tearing during long fights

•  Flat-forged (tataki) construction – Increases both strength and penetrating power

•  Straight point – Excellent penetration on short bites and during the fall

•  Silver-plated finish – Reduces unwanted light reflection while providing outstanding corrosion resistance

•  Hand-bent by specialist craftsmen at Hariyoshi Co., Ltd. (Japan) exclusively for Studio Ocean Mark

Assist Specs (30F)

•  Twin assist configuration

•  30 mm assist length

•  Special SOM solid ring

•  Fluoro-core assist line

•  Bag-through (nukitoshi) finish with minimal seki-ito for reduced water resistance and cleaner jig action

•  2 sets per pack

Why Anglers Choose the SEIGI 23 Hutozi 30F

This is not a generic “strong hook.” It is a purpose-built tool refined through years of testing specifically for Slow Pitch Jigging on bluefish. The combination of the long-shank geometry, straight point, and carefully balanced thick wire allows the hook to enter the mouth easily, penetrate deeply, and stay locked in the hard structure of the jaw — dramatically reducing the short-bite and pull-out problems common with other styles.

Recommended use: Pair with appropriate PE line, rod power, and drag settings for the target size. Always check and lightly touch up the chemically sharpened points before use.
