Fishing Tokyo Bay: the fish, the seasons, and the plan to catch them

What and where it is

Tokyo Bay is a large, sheltered, shallow-to-moderate sea bay enclosed by the Tokyo, Kanagawa and Chiba conurbation, fed by several rivers, with structure everywhere: river mouths, wharves, channels, the airport runways and bridge pilings. It is a turbid, food-rich, boat-fishing bay rather than a clear-water flat. Charter boats run from Tokyo, Yokohama and the Chiba ports.

The bay sits at the head of Sagami waters on the Pacific side of Honshu, ringed by one of the densest urban areas on earth. The Tama, Ara and Edo rivers (among others) pour nutrients and bait into it, the Tokyo Aqua-Line bridge-and-tunnel crosses the middle, and Haneda Airport sits on reclaimed land on the western shore. All that hard structure and moving water is why the fishing is good: predators hold on the river mouths, the channel edges, the wharves and the pilings, hunting the bait the rivers bring down.

It is not a place you wade or sight-fish. The water is coloured and the productive ground is offshore of the piers, so the way visitors fish it is from a charter boat. The boats are typically around 11 m (37 ft) and take up to about seven anglers, running out of the bay's ports for half-day and full-day trips (source: fishtokyo.com, as of 5 June 2026).

It is also the easiest world-class saltwater fishing to reach from a major city anywhere. You can be casting lures for seabass within sight of the skyline, an hour or so after leaving central Tokyo. That access, plus two genuinely strong targets and no fishing ticket to buy, is what makes the bay worth a session on a trip.

The fish, and where, when and how to catch each

Suzuki (Japanese seabass) on lures is the signature target, and tachiuo (hairtail) on a jig or tenya is the autumn prize. Aji (horse mackerel), kasago and mebaru (rockfish) and kochi (flathead) fill out the same boats. The cards below give you where, when and how for each, so you can match your dates and your kit to the fish.

Others, for context. The bay and the open water beyond it hold more, depending on the boat and the season (mackerel, the occasional bigger pelagic out wider for the dedicated trip). They are not why most visiting anglers come, so the five cards above are the trip: suzuki on lures and tachiuo on the jig are the headline, with aji, the rockfish and kochi filling the boat.

I have set each species out as a card. Read the one for the fish you want, then check the seasonal section for how it moves through the year, and follow the rig link to build the method.

How the fishing changes by season

Suzuki run all year, with the biggest fish in autumn and winter. Tachiuo is the autumn prize, roughly September to November and into the cold. Aji and kochi are the warm-season fish; the rockfish are the cold-season fallback. So autumn is the all-round peak: seabass big, hairtail on, and the supporting cast still about.

Here is the year in plain terms.

• Spring (March to May). Suzuki are about and feeding as the water warms; this is a good lure-casting window before the heat. Mebaru are still on through the early spring cold. Aji start to show as it warms.
• Summer (June to August). Suzuki keep going, often best early and late to beat the heat and the boat traffic. Kochi (flathead) come into their own on the sandy ground. Aji are reliable and a good family target. The middle of a hot, bright day is slow; fish the early start.
• Autumn (September to November). The peak. Tachiuo come on hard and fat, the standout autumn trip. Suzuki put on size as the water cools. Aji are still strong. If you can only pick one season, this is it.
• Winter (December to February). The biggest suzuki of the year, for the angler who will wrap up and fish the cold. Tachiuo run on into the early winter. Mebaru and kasago are the dependable cold-water bottom fish. Fewer boats, bigger fish.

What you can eat (and what to check first)

All the headline fish are eaten and prized. Suzuki is sashimi or grilled, tachiuo is sashimi or tempura, aji is the classic table fish, and kochi and the rockfish are good eating. There is no inland-style bag ticket for the sea. The one thing to check is the consumption guidance that can apply to fish from a heavily urbanised bay.

This is a busy, industrial sea bay, and its fish have long been monitored for contaminants. The Tokyo Metropolitan Government and its environmental research institute track dioxins and PCBs in Tokyo Bay fish, water and sediment as part of ongoing monitoring (source: Bureau of Environment, Tokyo Metropolitan Government, as of 5 June 2026). That monitoring exists; it does not amount to a blanket "do not eat" notice for the recreational angler, and the fish are caught, sold and eaten widely. The plain takeaway: eat what you catch in normal amounts, and if you plan to eat a lot of bay-caught fish, check the current Tokyo guidance rather than rely on a figure here, because the detail can change.

Everything else is the usual good practice. Bleed and ice a fish you mean to eat, handle the tachiuo's teeth with care, and follow your skipper's house rules on what to keep. Check the size and bag limits and any closed season before you keep a fish, and clean your kit between waters so you do not carry anything from one place to the next.

Licence and rules

No fishing ticket is required for rod-and-line sea fishing in Tokyo Bay. Sea fishing is largely licence-free in Japan, unlike the lakes and rivers, which need a cooperative day-ticket. The rules still apply: stick to legal methods, mind protected areas and ports, and note that some managed shore parks charge an entry fee. On a charter, the skipper handles the permissions.

The licence reality, plainly. Japan's licence picture is not like Europe or the USA, and it is the single most useful thing to get right. For a lake or river, you buy the managing fishing cooperative's day-ticket (yuugyoken, a recreational fishing ticket), sold at convenience stores, tackle shops or online. For the sea, including the open bays like Tokyo Bay, you usually need no ticket at all: ordinary rod-and-line fishing in the ocean is licence-free (source: Japan Bass Fishing Agent, "Do I need a fishing license in Japan?"; Fisheries Agency of Japan, as of 5 June 2026).

What "licence-free" does not mean. It does not mean no rules. There are still:

So there is nothing to buy before you go. Book a charter (or pick a shore park), turn up, and fish. The boat handles the permissions and supplies the tackle if you want it. The plain version, said once: for a lake or river in Japan, buy the cooperative's day-ticket; for the sea, you need no ticket, but the rules still apply.

Where to fish

Boat is the way to fish Tokyo Bay. The productive water is offshore of the piers, so a charter from Tokyo, Yokohama or the Chiba ports is the headline. Shore fishing exists at a few open piers and managed parks (Wakasu Seaside Park is free; Honmoku Fishing Park in Yokohama charges a small adult fee of ¥900, with under-12s free), but it is the budget option, not the main event.

The bay is coloured and the fish hold on structure offshore of the shore line, so the charter is what puts you on them. Here is how to think about access.

By boat (the headline). Charters run from ports all round the bay (Tokyo, Yokohama, and the Chiba side such as Futtsu). A half-day or full-day trip works the river mouths, the channel edges, the wharves, the bridge pilings and the open-bay drop-offs that you cannot reach from land. The boats supply tackle if you need it and know which structure is fishing. This is the way to fish suzuki properly and the only practical way to fish tachiuo. See "The boat" below for named operators.

From the shore (the budget option). A few open piers and managed parks give land-based access, mostly for aji, the rockfish and a chance at a smaller seabass:

• Wakasu Seaside Park (Wakasu Kaihin Koen), Koto, Tokyo. A purpose-built fishing pier of about 570 m along the east breakwater, free to fish, open roughly 06:00 to 21:00. The accessible shore option in Tokyo proper. Source: Tokyo Park / Wakasu Seaside Park, as of 5 June 2026.
• Honmoku Fishing Park (Honmoku Kaizuri Shisetsu), Yokohama, Kanagawa. A managed pier in Yokohama, ¥900 for an all-day adult ticket (¥450 junior high, ¥300 elementary, under-12s free), with rod, reel and bait available to rent. Open roughly 06:00 to 19:00 April to October and 07:00 to 17:00 November to March. The fee is for the venue, not a fishing licence. Source: Yokohama City fishing piers, as of 5 June 2026.

What depth and structure mean for method

• Shore piers and breakwaters: light bait for aji and rockfish on an inshore bait rig or a sabiki, and lure casting for a smaller seabass.
• River mouths, wharves and pilings (from a boat): suzuki hold here and come up to a cast lure. Work a minnow or vibration plug along the structure.
• The open channels and drop-offs (from a boat): tachiuo over the deeper water on a jig or tenya; aji over a marked shoal; kochi on the sandy edges.

Bank vs boat, and the time of day

From the shore you can take aji, rockfish and the odd smaller seabass at the free or low-fee piers, best early and late. From a charter you add suzuki properly and tachiuo at all, over the structure and the channels offshore. Trips start early (around 07:00) and low light is best. The middle of a hot, bright day is slow either way.

Plain version: if you only have the shore, fish a free or low-fee pier early or late for aji, rockfish and a chance at a small seabass. With a charter you fish suzuki on lures the way it is meant to be done, and in autumn you swap to tachiuo on the jig. Low light beats the middle of the day, and the change of tide is often the trigger.

This table is the core decision the trip turns on. It lives on the cheat sheet too. Read it as: pick your fish, pick where you are and when, and it gives you the rig.

The boat: guided charter, the way to fish it

A charter is how you fish Tokyo Bay. English-friendly boats run from the bay's ports for half-day and full-day trips, supplying tackle and knowing the structure. They are set up for suzuki on lures and tachiuo on the jig. Beginner and shared boat plans start from around ¥6,000 per person, with a typical English-friendly seabass trip from around ¥13,000 (2026, confirm with the operator). Book directly through the links below.

There is no licence to buy and no self-drive hire to arrange for the visiting angler: you book a guided charter, turn up at the port, and fish. The boats are typically around 11 m (37 ft) and take up to about seven anglers (source: fishtokyo.com, as of 5 June 2026). Trips start early, around 07:00, so plan your transport to the port.

On price

Beginner and shared sea-fishing plans on the bay start from around ¥6,000 per person, and a typical English-friendly seabass charter from around ¥13,000 per person (2026), varying by boat, length and target (source: Activity Japan; Tokyo-Japan-Fishing, as of 5 June 2026). Confirm the current rate, what tackle is included, and the meeting point when you book. Do not assume a figure: book through the operator.

Where to stay

You do not need to stay by the water here. Tokyo Bay's charters run from ports an easy reach of central Tokyo and Yokohama, so base yourself in the city near your port and your transport, and travel out for the early start. Pick a hotel near the line that serves your chosen port (Tokyo, Yokohama or the Chiba side).

This is the one Fishing Dan water where "stay near the fishing" means "stay in a global city". The practical plan is to book a hotel in central Tokyo or in Yokohama, close to the train line that reaches your charter's port, so the early-morning meet is simple. Confirm the meeting point with your operator first, then choose the accommodation that makes the 07:00 start easy.

• For a Tokyo-side charter, stay near the bay-side wards (around Koto, Shinagawa or Tokyo Station) for a short morning hop.
• For a Yokohama-side charter, stay near Yokohama or Minato Mirai.
• For the Chiba-side boats (such as the Futtsu tachiuo trips), check the rail or road time from your base and allow for the early start.

Because there is no licence to buy and no shore tackle shop you must visit first, accommodation is about the commute to the port, not about being on the water. The free shore option at Wakasu Seaside Park, if you want a land-based session too, is in Koto on the Tokyo side.

The methods, and the rigs to build them

Two rig pages cover the bay. The jigging-rig page is the light braid-to-leader lure outfit: cast minnows and vibration plugs for suzuki, and jig a metal for tachiuo. The inshore-bait-rig page covers bait on or near the bottom: aji, the rockfish, kochi, and the tenya baited hook for hairtail. Both are joined to the leader with the FG knot.

Map of fish, where and when, to a rig. The build instructions and the knots live on the rig pages, so I link rather than repeat them.

• Suzuki on lures, from a boat → jigging rig. The same light saltwater outfit, cast and retrieved rather than jigged straight down: a minnow or vibration plug, or a soft swimbait on a jighead, on PE 0.8 to 1 braid and a 16 to 24 lb fluorocarbon leader.
• Tachiuo on a metal jig, from a boat → jigging rig. A light jig worked off the bottom and up. The bite often comes on the fall, so stay in contact.
• Tachiuo on the tenya, from a boat → inshore bait rig. The tenya is a weighted hook baited with a strip of fish, worked on a slow lift-and-drop. It is a baited-hook-on-a-leader method, closest to the inshore bait rig.
• Aji, from a boat or pier → inshore bait rig (or a ready-made sabiki dropper, see the gambe / sabiki). Light bait over a shoal.
• Kasago and mebaru (rockfish), on structure → inshore bait rig. Light bait dropped to the bottom and the pilings.
• Kochi (flathead), on the sand → inshore bait rig for bait, or the jigging rig soft-lure crawled low.

The knot that ties the saltwater outfit together is the FG knot, the strong, slim braid-to-leader join that runs through the rod guides. The Palomar ties the jig, the lure clip and the swivels; the snell knot ties the bait hooks on the inshore rig. Each rig page links the knots it needs.

Build your kit (the kit builder and the shopping list)

Pick your fish and whether you are on a pier or a boat, and the kit builder trims the shopping list and the rigs to exactly what you need. One light saltwater outfit, PE 0.8 to 1 braid, a fluorocarbon leader and a small box of jigs, plugs, hooks and weights cover the bay. Most charters can supply tackle, so confirm before you carry your own. The full list is below, grouped, with no brands and no prices.

That is the whole list. One light saltwater outfit, a spool of PE braid, a spool of fluorocarbon leader, and a small box of jigs, plugs, jigheads, tenya, hooks and weights cover the bay. Add the light bait rod and a sabiki only for a shore session. Most charters supply tackle, so the simplest first trip carries nothing but a hat and a cool box. Buy generic sizes and types; you do not need a named brand to catch a seabass.

A trip checklist

Before you go: pick your season (autumn for the all-rounder), choose shore or charter and book the boat, confirm what tackle is supplied, note there is no licence to buy for the sea, pack the one shared kit (or nothing if the boat supplies it), and check the current consumption guidance if you mean to eat a lot. Then print the cheat sheet and take it with you.

Do this in order:

1. Pick your season. Autumn (September to November) is the all-round peak: big suzuki and tachiuo on. Summer for kochi and aji, winter for the biggest seabass and the rockfish.
2. Choose shore or charter, and book it. Charter for suzuki on lures and tachiuo at all (links above); free or low-fee piers (Wakasu Seaside Park, Honmoku Fishing Park) for aji, rockfish and a small seabass. Book the boat ahead, and note the early start.
3. Confirm the tackle and the meeting point. Ask the operator what is included and where to meet. Most charters supply tackle, so you may not need to bring any.
4. No licence to buy for the sea. There is no fishing ticket for Tokyo Bay. Just follow the rules: legal methods, mind protected areas and ports, and pay any shore-park entry fee on the day.
5. Pack the one kit (or nothing). If you bring your own: the light saltwater outfit, PE braid, a fluorocarbon leader, and the small box of jigs, plugs, hooks and weights. The shopping list above (trimmed by the kit builder) is your packing list. Pliers for the tachiuo's teeth.
6. Check the consumption guidance if you plan to eat a lot of bay-caught fish, and pack a cool box for what you keep.
7. Print the cheat sheet and fold it into the box. Get the printable cheat sheet

Common mistakes

The big ones: trying to fish the bay seriously from the shore, missing the autumn tachiuo window, fishing the bright middle of a hot day, bringing the wrong line, mishandling the tachiuo's teeth, and assuming the sea needs a ticket. None is hard to avoid once you know.

• Trying to fish it seriously from the shore. The productive water is offshore of the piers. Shore fishing gets you aji, rockfish and a small seabass; for suzuki on lures and tachiuo at all, you want a charter.
• Missing the autumn tachiuo window. Hairtail are the autumn prize, roughly September to November and into the early winter. Outside that, do not expect them; build the trip around suzuki instead.
• Fishing the bright middle of a hot day. Low light and the change of tide are the triggers. Trips start early for a reason; the middle of a bright summer day is slow.
• Bringing the wrong line. PE 0.8 to 1 braid to a 16 to 24 lb fluorocarbon leader, joined with the FG knot, is the standard. A leader that is too heavy kills the lure action; one that is too light is cut by the tachiuo's teeth.
• Mishandling the tachiuo. Hairtail have a serious set of teeth. Use long-nose pliers or a disgorger to unhook them, and keep your fingers clear.
• Assuming the sea needs a ticket. It does not. Tokyo Bay rod-and-line fishing is licence-free. The lakes and rivers need a cooperative day-ticket; the sea does not. Do not waste time looking for one.
