About this app
Japan's fishing forecast app — bite times, weather, moon phase & lure picks for Lake Biwa, Kasumigaura, Saroma and more.
Will it bite today? (釣れるかな？)
That's the question every angler asks before packing the tackle box.
TsureruKana helps you decide when to fish, what to throw, and where to start by combining weather, moon phase, atmospheric pressure, and feeding activity into an easy-to-understand fishing forecast for Japan's major lakes and coastal waters.
Whether you're heading out before sunrise or planning a weekend trip, check the conditions in seconds.

📋 Lake Rules & Regulations

HOW IT WORKS
TsureruKana combines several environmental factors, including:
• Moon phase (Solunar)
• Weather conditions
• Atmospheric pressure
• Feeding activity windows
These factors are analyzed together to estimate fishing conditions and provide practical recommendations.
LOCATION OPTIONS
You can choose how you want to select your fishing location.
📍 Check conditions for the place you're currently at.
🗺️ Choose a predefined location from the supported locations, or save your own.
When using your current location, it is used to provide relevant fishing information and is not continuously tracked in the background.
WHO IS IT FOR?
Whether you're new to fishing or you've been bass fishing Japan's lakes for years, TsureruKana helps you make more informed decisions before every trip.
Because even when nobody knows for sure...
...it's always nice to have the odds on your side.
Fishing forecasts are estimates based on environmental data and do not guarantee fishing success.
