Early Summer Hokkaido: Flatfish and Rockfish Bite Strong at Dawn and Dusk

This is Artificial Lure with your Hokkaido fishing report. Around Hokkaido today we’ve had classic early-summer conditions: cool, clear air in the north, a bit milder and breezier along the Pacific side. Daytime highs have been sitting in the upper teens to low 20s Celsius with light to moderate wind, mostly from the south and southeast along the Pacific and lighter westerlies on the Sea of Japan side. Skies have been partly cloudy overall, with sea conditions ranging from slight chop offshore to fairly calm in the bays. Sunrise came early, just after 3:50 a.m. across most of Hokkaido, with sunset a little before 7:20 p.m. That long twilight window has been key; the bite has clearly been better right around first light and again in the last hour of sun. Midday is slower unless you’re fishing deep or in strong current. Local tide tables for the Ishikari and Muroran areas show a decent-sized daytime tide today. The stronger moving water late morning and just before dark has fired up the fish, especially in inlets and river mouths where that current really squeezes. Inshore, anglers have been doing well on **flounder** and **Japanese halibut (hirame)** off sandy beaches and harbor mouths. Reports from local tackle shops around Ishikari Bay and Tomakomai say several nice flatfish in the 40–60 cm class were landed over the past couple of days on soft plastics and strip baits fished slowly along the bottom. A few larger halibut over 70 cm have come from small boats drifting just outside the breakwaters. Along rocky shorelines and harbor walls, **rockfish (mebaru), greenling (ainame), and fat cabbages (kuma-soi)** have been biting steadily. Evening sessions with light tackle are producing good numbers, often ten or more fish in a couple of hours if you stay mobile. Most are pan-sized, but there are enough 30 cm–plus fish mixed in to keep things interesting. Sea-run **cherry salmon** are now mostly tapering off on many rivers, but a handful of bright fish are still being picked up early in the morning near river mouths on spoons and minnow plugs. In the eastern offshore grounds, charter boats have started to see better numbers of **Pacific cod** and mixed bottom fish, with a few **hokke** (Atka mackerel) showing up as well. As for lures, the standout choices have been: - For flounder and halibut: 3–4 inch shads and curly-tail grubs on 10–20 g jig heads in natural baitfish colors, or small metal jig heads tipped with salted sandworm. Slow, dragging retrieves along the sand are working best. - For rockfish and greenling: small rubber jigs, 5–10 g, with creature baits in dark brown, black, or purple, worked near structure. Short lifts and pauses are drawing strikes. - For salmon near river mouths: 18–28 g spoons and slim minnow plugs in silver, blue, or chartreuse, retrieved a bit faster in the current seams. Best bait right now: - **Salted sandworms and isome** for flatfish. - **Chunked sardine or herring** for halibut and cod from boats. - **Fresh shrimp or squid strips** for rockfish and greenling around harbor structure. If you’re planning a trip, here are a couple of hot spots to consider: - **Ishikari Bay and river mouth** on the Sea of Japan side. Fish the sandy stretches just down-current of the river mouth at first light for flounder and hirame, then move to the tetrapods and harbor walls toward evening for rockfish. Work the edges where clear seawater mixes with the slightly stained river flow. - **Tomakomai and Muroran harbors** on the Pacific side. The outer breakwaters and nearby rocky points have been producing mixed bottom fish, and the deeper pockets close to the shipping channels are holding better-sized halibut. Time your session to the stronger part of the tide and let your jig or bait sweep naturally with the current. Focus on dawn and dusk, follow the moving water, and don’t be afraid to change lures until you find what they want. Hokkaido’s early summer window is open now, and the fish are waking up with the season. Thanks for tuning in, and don’t forget to subscribe for more local fishing updates.
