Yes— there are big rockfish cruising the rocky bottoms and offshore structures around Yokosuka, Kanagawa. Sagami Bay and the Yokosuka area host a mix of large rockfish species that love staying tight to rubble, wrecks, piers, and ledges. In mid fall, when the temps cool and bait starts to stack up around structure, you’ll see the bigger bruisers cruising those spots.
Where to target
- Focus on rocky bottoms, breakwaters, and offshore reefs near Yokosuka and Sagami Bay. Look for vertical relief around the coast and any sunken structure. Tidal movement helps; fish tend to feed more on moving water.
- Best bites often come on dawn or dusk during mid fall when the water is cooling and vis is good enough to spot structure from the boat or pier.
Gear and rigging tips
- Use heavy tackle: 30–60 lb braided line with a fluorocarbon leader in the 16–40 lb range. A sturdy rod in the 6'8"–7'6" range and a reel with solid drag will handle bigger rockfish on heavier jigs.
- Lure/rigs: go vertical with metal jigs (60–150 g) or slow-pitch style swimbaits and soft plastics that imitate small baitfish. Bucktails and paddle-tail swimbaits are solid bets around rock bottoms.
- Bait options: live shrimp, small fish, or cut squid work well as bottom bait if you’re anchored near structure. For jigging, bring a selection from soft plastics to metal jigs.
Practical tips & techniques
- Try a two-pronged approach: drift the structure with live bait to tempt cautious fish, then drop a weighted jig down the edge to work the bottom and trigger thumps.
- Cast beyond a likely rock shelf and let the lure sink to the bottom; sweep up with a steady jigging cadence to keep it bouncing along the bottom where rockfish lurk.
- Watch wind and current; a steady current makes it easier to feel the bite and control your line.
- Weather matters in mid fall: water temps around the upper to mid-60s F (around 18–20 C) are typical—fishes move into shallower sections during warming spells; plan for calmer mornings if seas look choppy.

If you stick to structure, bring the right gear, and time your sessions with the tides in mid fall, you’ll be in prime position to land some of Yokosuka’s bigger rockfish. Stay patient, adjust your depth with the current, and keep your line tight—they Rumble when they’re ready to bite. Tight lines and may the rod arc with a big rockfish soon! 🪝🎣
