Osaka Bay is a sea you can reach by train from central Osaka. What you catch changes a lot with the season: rockfish and scorpionfish in spring, horse mackerel and sardines on sabiki rigs in summer, hairtail and young yellowtail in autumn, and flounder and greenling in winter.

This guide is based on the official monthly catch calendars of three fishing parks on Osaka Bay: Nanko Fishing Park, Amagasaki City Fishing Park, and Totto Park Koshima. Two of them rent rods, so you can go fishing in Osaka even if you didn’t bring any gear.

What you catch depends on water temperature, tides, and where the schools are that year. The months in this guide come from each park’s own calendar. They are a guide, not a promise of a catch.

Quick answer:

  • Most fish species: Summer to autumn has the most fish species in Osaka Bay.
  • For beginners: Late spring to early autumn, with a rental rod and a sabiki rig at Nanko or Amagasaki.
  • For bigger fish: Totto Park Koshima, near Kansai Airport, if you bring your own gear.

What You Can Catch in Osaka Bay by Season

Spring (March–May): rock-dwelling fish and the first big fish

  • Totto Park Koshima:
    • Rockfish (mebaru) and marbled flounder (makogarei) until May, and scorpionfish (kasago) until April.
    • Red sea bream (madai) and olive flounder (hirame) from April.
  • Amagasaki City Fishing Park: Fat greenling (ainame) until May and surfperch (umitanago) from March to May.

  • All three parks: Black sea bream (kurodai) and Japanese sea bass (suzuki) are on the calendar year-round.

Spring isn’t yet the season for catching lots of fish on a sabiki rig. For horse mackerel, the calendars point to May at Nanko and April at Totto Park.

Summer (June–August): sabiki season

  • Nanko and Amagasaki: Horse mackerel (aji), sardines (iwashi), and mackerel (saba) on sabiki rigs. Amagasaki also lists Japanese sardinella (sappa) and halfbeak (sayori).

  • Amagasaki: Japanese flying squid (surume-ika) from June to August.
  • Totto Park: Barred knifejaw (ishidai) and thread-sail filefish (kawahagi) in July and August.
  • Hairtail (tachiuo): From August at Nanko and Totto Park.

The parks open early in summer. Nanko opens at 5:00 from April to November, and Amagasaki opens at 5:00 from July to October. Fish in the morning, before the heat builds.

Autumn (September–November): hairtail and big fish

  • Hairtail: On the calendar at all three parks (Nanko Aug–Nov, Amagasaki Sep–Nov, Totto Park Aug–Nov).
  • Young yellowtail:
    • At Totto Park, hamachi (Sep–Dec) and mejiro (Aug–Dec). These are names for yellowtail at different sizes.
    • At Nanko, yellowtail (Sep–Nov).
  • Bigfin reef squid (aori-ika): Totto Park (Aug–Nov).
  • Sabiki fishing: Horse mackerel, sardines, and mackerel keep biting at Nanko and Amagasaki.
  • Totto Park Koshima: Red sea bream and filefish. From November, rockfish, scorpionfish, and marbled flounder come back.

Winter (December–February): rock-dwelling fish and flounder

  • Totto Park Koshima: Rockfish, scorpionfish, marbled flounder, horse mackerel, and octopus (Dec–Jan).
  • Amagasaki City Fishing Park: Fat greenling, flounder (karei), and black scraper (umazura-hagi).
  • Nanko Fishing Park: Scorpionfish, largescale blackfish (gure), sea bass, and black sea bream. These four are the only fish on Nanko’s calendar in winter.

All three parks close early in winter: Nanko and Amagasaki at 17:00, and Totto Park at 18:00. Night fishing isn’t possible at the fishing parks.

Fishing Methods Used in Osaka Bay

The months below follow the three fishing parks’ official calendars.

Sabiki fishing (horse mackerel, sardines, mackerel, sardinella)

A sabiki rig has a row of small hooks dressed with tiny lures. You attach a small basket filled with chum (tiny krill called ami-ebi) to draw in a school of fish. When a school arrives, you can catch several fish at once.

  • Horse mackerel season: May–November at Nanko, June–November at Amagasaki, and April–February at Totto Park.
  • Rental rods:
    • At Nanko, a rental rod (¥1,000) comes with a sabiki rig.
    • Amagasaki also rents rods with a rig (¥1,500). Ask on site which rig is included.

Float fishing with live shrimp (sea bass, rockfish, greenling, black sea bream)

A live shrimp is hooked and drifted under a float at the depth you want to fish. In the Kansai region, tackle shops sell these shrimp as shirasa-ebi. Scattering live shrimp as chum while you fish is called ebi-maki fishing.

  • The shop at Amagasaki City Fishing Park sells shirasa-ebi, though it can sell out.
  • The park held a sea bass ebi-maki tournament in February–March 2026.

Probing along the wall (scorpionfish, rockfish, greenling)

You drop a weight to the bottom and slowly work it along the seawall and into gaps between rocks. This is the way to target fish that live among rocks.

  • Scorpionfish: Year-round at Nanko, November–April at Totto Park.
  • Rockfish: November–May at Totto Park.
  • Fat greenling: December–May at Amagasaki.

Otoshikomi: dropping bait along the wall (black sea bream)

You let a bait sink slowly right next to the seawall. Black sea bream is on the calendar year-round at all three parks.

  • At Totto Park, kishu-zuri and dango fishing (methods that use rice bran or sand balls as chum) are not allowed.

Live-bait fishing, called nomase (young yellowtail, olive flounder, sea bass)

You hook a small live horse mackerel, often one you caught on a sabiki rig, and let it swim to attract a bigger predator.

  • Totto Park: Hamachi (Sep–Dec), mejiro (Aug–Dec), and olive flounder (Apr–Jun and Nov–Dec).
  • Nanko: Yellowtail (Apr–May and Sep–Nov).

Basket float fishing, called kago-zuri (red sea bream, other fish)

A basket of krill hangs below a float and drifts out with the current.

  • Red sea bream at Totto Park: April–June and September–December.
  • Long casting: Each park has its own rules on casting far, so ask the park whether basket float fishing is allowed.

Hairtail fishing (float fishing and lures)

Hairtail becomes active from evening into the night. Anglers target it with a float rig baited with fish strips, or with lures.

  • Season: August–November at Nanko, September–November at Amagasaki, and August–November at Totto Park.
  • Closing time: The fishing parks close at night, so your best window is the evening before closing:
    • Nanko closes at 19:00 (April–November).
    • Amagasaki closes at 20:00 (July–October).
    • Totto Park closes at 20:00 (March–November).

Lure fishing (young yellowtail, hairtail, sea bass)

You cast a metal jig or another lure and reel it in so it looks like a swimming baitfish. Each park has its own rules on lures:

  • Nanko: The official site says lures are OK.
  • Amagasaki: The rules say “dangerous casting and lure fishing are prohibited.”
  • Totto Park: The rules don’t mention lures, so ask the park.

Eging (bigfin reef squid, golden cuttlefish)

An egi is a shrimp-shaped lure for squid. Follow each park’s lure rules above.

  • Bigfin reef squid: August–November at Totto Park.
  • Golden cuttlefish: April–June at Nanko.
  • Awaji Island: Anglers on the Awaji Island coast are asked to release bigfin reef squid. The request covers squid with a mantle under 15 cm all year, and all sizes from July 1 to September 30.

Octopus fishing

You drop an octopus rig to the bottom and work it along the base of the seawall.

  • Nanko: June–August.
  • Totto Park: June–September and December–January.
  • At a fishing park: If you have any questions, call the park.

Bottom fishing (flounder)

You leave the bait on the bottom and wait for a bite.

  • Season: December–February at Amagasaki, and November–May at Totto Park (marbled flounder).
  • Long casting: Casting far is prohibited at Nanko, and Amagasaki prohibits “dangerous casting.”

Day Plans: Combine Fishing with Osaka Sightseeing

Plan 1: Fish at Nanko, then explore the Tempozan waterfront

In the morning, rent a rod at Nanko Fishing Park and try sabiki fishing. In the afternoon, change from the New Tram to the Chuo Line at Cosmosquare Station and ride to Osakako Station for the Kaiyukan aquarium and the Tempozan waterfront.

How to get to Nanko:

  1. Take the New Tram to Ferry Terminal Station (フェリーターミナル).
  2. From the Ferry Terminal Ekimae stop, take Osaka City Bus route 15 to Nanko-minami 6-chome (南港南六丁目), about 10 minutes.

For the return bus times and tips for the day, see our Nanko Fishing Park guide.

The New Tram is an Osaka Metro line, so an Osaka Metro pass covers your train rides from Nanko to Tempozan.

Plan 2: Fish at Amagasaki, then visit Koshien

The nearest station to Amagasaki City Fishing Park is Mukogawa on the Hanshin Main Line. Koshien Station is two stops away on the same line, so you can head to Koshien Stadium after fishing.

Plan 3: Fish at Totto Park on your first or last day, near Kansai Airport

Totto Park Koshima is about 20 km from Kansai International Airport. There’s no rental gear, so you’ll be carrying your own, and a car makes that much easier. The park has free parking for 100+ cars.

Want to Go Boat Fishing in Osaka Bay?

We couldn’t find any Osaka Bay fishing boat tours on Klook or KKday (as of September 2026). For boat fishing on Osaka Bay, the fishing hotel Awakan in Sumoto, on the east side of Awaji Island, runs boat fishing trips. There are plans for hotel guests and day visitors, and shared trips go out with as few as one person.
