Yasuo Nishimoto’s 5-Year Journey to the Ultimate Tuna Rod
The Mastermind: Yasuo Nishimoto
Yasuo Nishimoto is the premier field tester for DEEP LINER, holding the absolute trust of founder Masayoshi Higashimura. As a pioneer of Super Deep Jigging in Japan, Nishimoto has perfected the "Power Slow Game"—a specialized method designed to trigger strikes from massive tuna that have become wary of traditional approaches. This rod is the culmination of his vast experience and relentless field testing.
Concept: Never Sacrifice the "Joy of Manipulation"
"There are rods designed to let you just 'hold on' while the rod bends. But in those designs, the soul of slow-pitch—the ability to truly control the jig—inevitably suffers. I didn't want to lose the thrill of making the fish bite." — Yasuo Nishimoto
The CROSS-BORDER TUNA was developed as an aggressive weapon: where high-performance jig manipulation meets the raw power needed to dominate giant tuna.
The Strategy: Constant Pressure (Underarm Fight)
Specifically designed for the "underarm fight," this rod allows experts to load the blank to its limit. By maintaining constant pressure and recovering line the moment the rod snaps back, it closes the distance inch by inch. It is a precision tool for those who know exactly how far they can push a blank.
Tactical Design: Pure Necessity
-
6'3" One-Piece Construction: The optimal length to clear the boat's hull during the final circling stages of a fight, preventing line breaks. The one-piece design eliminates "blank twist" and maximizes sensitivity under extreme loads.
-
Custom "Size 19" Reel Seat: A collaborative breakthrough with Fuji Kogyo. This new carbon seat provides maximum rigidity, ensuring it won't loosen during grueling, long-duration fights while remaining ergonomic for the angler’s hands.
Model Lineup: Target-Specific Power
| Model | Target Class | Focus |
| L (Light) | Yellowfin (20–50kg) | High-response jigging where precise action triggers the strike. |
| M (Medium) | Big Game (50–100kg) | The series core. Balances deep-water repulsion with fighting tenacity. |
| H (Heavy) | Monster Bluefin (100kg+) | Brute-force model designed to transmit maximum reel power. |
