I stopped at Lake Toya while driving back from Hakodate near the end of March. I would have been happy simply to cast before the season closed—but the lake surprised me with a powerful rainbow trout measuring over 50 cm.
Lake Toya is one of Hokkaido’s best-known caldera lakes and an exciting destination for shore and boat anglers. Fishing is regulated: you need a permit, may fish only during designated seasons and hours, and must stay outside five year-round no-fishing zones.

Do You Need a Fishing License at Lake Toya?
Yes. You must obtain a Lake Toya recreational fishing permit before you begin fishing. The permit is issued under the local fishery rules and is separate from any fishing permission elsewhere in Hokkaido.
Lake Toya Fishing Permit Prices
| Target | Method | Day Permit | Annual Permit |
|---|---|---|---|
| Kokanee, rainbow trout, and yamabe | Shore fishing | ¥1,200 | ¥20,000 |
| Kokanee, rainbow trout, and yamabe | Boat fishing | ¥1,500 | ¥20,000 |
| Shrimp | Shore | ¥500 | — |
| Wakasagi smelt | Shore | ¥500 | — |
An annual permit is valid from June 1 through March 31 of the following year. It is most economical when purchased near the beginning of the June season.

Five Year-round No-fishing Zones
Lake Toya has five permanent no-fishing zones. Boundaries are not something to estimate casually from a blog description: use the cooperative’s official restricted-area map and obey every sign at the lake.
Important: A Lake Toya permit covers fishing governed by the lake’s recreational fishing rules. It does not by itself grant permission to fish tributaries, private land, restricted shorelines, marina facilities, or other waters. Confirm separate rules before entering or fishing any river.
How to Choose a Shore-fishing Area
Lake Toya is large, exposed, and highly variable. Instead of publishing a precise “secret spot,” I recommend choosing legal public access where you can park without obstructing residents or businesses, enter without crossing private land, and remain clearly outside every no-fishing zone.
What to Look For
- Shoreline contours where shallow water drops into deeper water
- Wind and current that concentrate food, while still allowing safe casting
- Stable footing and a safe route back before darkness
- Enough space to avoid other anglers, swimmers, boats, and local facilities
Do not assume that the mouth of a river is legal simply because it looks productive. Several restricted zones are defined around river mouths and discharge channels, and tributaries may have different regulations from the lake.
Season-by-season Overview
June: Shore and Boat Season
June is the only part of the summer trout season when both shore and boat fishing are open. It is a popular period for anglers targeting kokanee. Expect competition at accessible areas and respect other lake users.
July–August: Shore Fishing Only
Boat fishing for the listed trout species closes after June, while shore fishing continues through August 31. Summer weather can make fish hold deeper, and early or late sessions may be more comfortable—but fishing is permitted only between 4:00 a.m. and 7:00 p.m.
December–March: Cold-water Season
Shore and boat fishing reopen for the listed trout species from December 1 through March 31. This season can produce memorable fish, but cold rain, snow, ice, strong wind, and short daylight make preparation essential.
Late-March Fishing Report: A 50 cm-plus Rainbow Trout
I stopped at Lake Toya while traveling from Hakodate toward Sapporo near the end of March. It was almost the final day of the winter season. I spent roughly two hours shore fishing without a response as the temperature fell and cold rain began.
I moved to another legal shoreline section with more water movement. I am intentionally not publishing the exact location: access and regulations matter more than sending additional pressure to one small area.
After several empty casts, I remembered advice I had received in Hakodate: slow down and give the fish time to inspect the lure. Instead of retrieving aggressively, I let it hang and drift under light line tension.
The lure was a compact jig originally intended for saltwater fishing, fitted with a fly-like tail. I maintained just enough tension to let it move slowly in the current—and the trout struck.
The fish measured a little over 50 cm, with deep red cheeks and an unusually heavy body for its length. It was one of those fish that immediately explains why anglers keep returning to Lake Toya.
Three Lessons from the Catch
- Slow down: a restrained presentation worked after faster retrieves failed
- Control line tension: light tension let the lure drift while remaining detectable
- Experiment: an overlooked saltwater jig produced the fish of the trip
Recommended Shore-fishing Tackle
There is no single ideal setup for every part of Lake Toya. For general shore casting, many anglers will find an 8–10 ft spinning rod and a 2500–3000-size reel more practical than a short stream rod. Use a line and leader strong enough for large trout and abrasion around rocks.
- Long-casting spoons and compact metal jigs
- Minnows suited to the depth and wave conditions
- Landing net with adequate reach
- Polarized glasses and waterproof footwear with secure grip
- Cold-weather layers, gloves, and rain protection outside summer
Lake Toya Fishing FAQ
- Can a beginner fish at Lake Toya?
-
Yes, but it is not an unrestricted tourist fishing pond. Beginners must buy the correct permit, understand the no-fishing zones, choose safe public access, and prepare for rapidly changing weather. Fishing success is never guaranteed.
Q
- Can I fish from shore without a boat?
-
Yes. Shore fishing is permitted during the designated shore seasons. Boat fishing has a shorter summer season, so July and August are shore-only for the trout species covered here.
Q
- Can I fish at night?
-
No. The listed fishing hours are 4:00 a.m. to 7:00 p.m.
Q
- May I keep the fish I catch?
-
The cooperative requires fish measuring 15 cm or less to be released. Follow all current possession and species rules, keep only what you will use, and handle released fish carefully. Never eat freshwater fish raw unless a qualified local food-safety authority confirms that it has been processed safely for raw consumption.
Q
- Does the lake permit allow fishing in nearby rivers?
-
Do not assume so. The Lake Toya permit and rules do not establish permission for every tributary or adjoining water. Check the applicable river regulations, land access, and any posted restrictions separately.

Lake Toya Fishing Summary
- Buy the appropriate permit before fishing
- Shore trout seasons: June 1–August 31 and December 1–March 31
- Boat trout seasons: June 1–30 and December 1–March 31
- Fishing hours: 4:00 a.m.–7:00 p.m.
- Check all five permanent no-fishing zones on the official map
- Do not treat the lake permit as permission to fish tributaries
Lake Toya is not easy water, and that is part of its appeal. The lake can deliver an unforgettable trout even at the end of a cold March session—but only after the practical work of checking regulations, buying a permit, choosing legal access, and preparing for Hokkaido weather.
