Kujaku, One Piece’s Marine Officer You Need to Know

One Piece Itajaga LOG.4 — Kujaku Metallic Card (OP4-20 N)

Japan’s Shokugan Tradition and the Itajaga Card Format

Itajaga cards are Bandai trading cards sold alongside a flat piece of tablet gum — which is precisely where the name comes from. That combination puts them in the shokugan category: a distinctly Japanese form of confectionery sold together with a collectible. The tradition stretches back to the Calbee Kamen Rider snack cards of the 1970s and 1980s and has remained a fixture in Japanese convenience stores, candy shops, and toy retailers ever since, pairing popular anime and manga licenses with small, affordable collectibles.

Bandai’s One Piece Itajaga LOG series runs across successive volumes — LOG.1 through LOG.4 — each covering a wave of characters from the series. LOG.4 draws from the Egghead arc, the storyline that began appearing in the manga around 2022 and moved to television in 2024. The card in this listing is numbered OP4-20 N: “OP4” identifies the fourth volume, “20” is its position within the set, and “N” designates Normal rarity. Despite that rarity tier, the card carries a metallic surface treatment — a reflective, light-catching finish that sets it apart from standard printed cards in the same set.

Kujaku: A New Face in the Marine Hierarchy

One Piece is the manga Eiichiro Oda has published in Weekly Shonen Jump since 1997. Its anime has aired on Fuji TV since 1999, and the series has surpassed 500 million volumes sold globally by publisher count. When Netflix released a live-action adaptation in 2023, it introduced a fresh wave of international fans to a franchise that was already one of the largest in manga history.

Kujaku is a female Marine officer introduced during the Egghead arc — one of the most recent chapters of an ongoing story. She is recognizable by her long blonde hair, pink-accented Marine hat, and naval uniform, and she carries a distinctive staff-type weapon. The card’s face makes her affiliation explicit: “MARINE” and “KUJAKU” are both printed on it. Her background adds a layer of interest for readers following the current storyline: she is identified in the manga as the granddaughter of Tsuru, a veteran Marine vice admiral known for wielding the Wash-Wash Devil Fruit. As a character who has only recently entered the story, merchandise depicting Kujaku is still limited compared to longer-established figures in the cast.

The left edge of the card shows small red, brown, and green indicators — markers that appear across collectible card formats and likely represent attributes or parameters, though their precise function within the Itajaga LOG system is not confirmed by official documentation.

What Draws International Collectors to Japan-Only Card Series

The Itajaga series circulates primarily through Japanese domestic retail, with no significant official export channel. That limited distribution means collectors outside Japan typically encounter these cards only through import sellers. For fans who discovered One Piece through its Netflix adaptation or its long-running anime, finding Egghead-arc merchandise in particular can require some effort — the arc is current, and the range of available goods tied to its newer characters is still expanding.

The metallic surface finish gives this card a display-quality presence that standard printing does not replicate: the sheen shifts as the card moves relative to light, which is part of why metallic treatments appear across the Itajaga set even at Normal rarity. The card is stored in a clear protective sleeve, consistent with collector-minded handling from the outset.
