Lure rods: pick the rod by the fish

Big fish need a rod with a long line; small fish take any rod. Buy by the fish:
• 27 species (e.g. Raigyo, Brown trout, Namazu) need line strength ×3–15 or more: the small lure rod (¥500, areas 1, 2, 3, 5, 6)
• 11 species (e.g. Oo-unagi, Kokuren, Akame) need line strength ×24 or more: the heavy-fish lure rod (¥650, area 4)

Line strength ×N is how far a fish may run before the line breaks and the hook is lost; big fish are decided here (the giant eel needs ×24). The rod also sets where the fight meter starts, which is how many mistakes you can afford: the small lure rod gives the best start against fish up to 15 cm; the large lure rod gives the best start against fish of 16–35 cm; for fish over 35 cm almost any rod is the same; using the heavy-fish lure rod on small and mid-size fish loses 1.0 mistakes on average, so keep it for fish over 35 cm.

Small lure rod

Never sold anywhere: the medium lure rod. Only sold by the special rod seller: the heavy-fish lure rod. Casting and lure rods give you less time to aim below 100 HP; restore HP before you fish.

Casting rods: pick the rod by the fish

Big fish need a rod with a long line; small fish take any rod. Buy by the fish:
• 25 species (e.g. Raigyo, Namazu, Numagarei) need line strength ×18 or more: the small casting rod (¥250, areas 1, 3, 4, 5, 6)
• 1 species (e.g. Kamuruchi) need line strength ×21 or more: the medium casting rod (¥600, areas 2, 4, 5, 6)
• 4 species (e.g. Oo-unagi, Aouo, Unagi) need line strength ×24 or more: the two-handed casting rod (¥1,500, area 6)

Line strength ×N is how far a fish may run before the line breaks and the hook is lost; big fish are decided here (the giant eel needs ×24). The rod also sets where the fight meter starts, which is how many mistakes you can afford: the small casting rod gives the best start against fish up to 15 cm; the medium casting rod gives the best start against fish of 16–35 cm; for fish over 35 cm almost any rod is the same; using the two-handed casting rod on small and mid-size fish loses 1.4 mistakes on average, so keep it for fish over 35 cm.

Fly rods: pick the rod by the fish

Big fish need a rod with a long line; small fish take any rod. Buy by the fish:
• 30 species (e.g. Brown trout, Amemasu, Sakuramasu) need line strength ×3–15 or more: the medium fly rod (¥400, areas 1, 2, 3, 5)
• 3 species (e.g. Aouo, Black bass, Nijimasu (rainbow trout)) want line strength ×24, but the longest rod is the large fly rod (¥450, areas 1, 2, 3, 4) (×21); it works, with some risk of the line breaking

Line strength ×N is how far a fish may run before the line breaks and the hook is lost; big fish are decided here. The rod also sets where the fight meter starts, which is how many mistakes you can afford: the medium fly rod gives the best start against fish of 16–35 cm; for fish over 35 cm almost any rod is the same; using the large fly rod on small and mid-size fish loses 1.7 mistakes on average, so keep it for fish over 35 cm.

More aim time lets you move the target longer. A higher line strength means the fish can pull farther before tackle is lost. The numbers are only for comparing rods, not metres or power. Fish can still escape other ways.

When should I choose this rod?

For fish that line strength ×3 holds (38 of 72 species); best start against 56 species; worse against fish of 16–35 cm (9 species)

Why and what to compare

Full recommendation

Line strength ×3 is how far a fish can run before the line breaks and the hook is lost. This rod holds 38 of 72 species; the other 34 species (e.g. Oo-unagi, Kokuren, Akame) run farther, so they need a longer rod. It gives the best fight start against 56 of 72 species but is worse against fish of 16–35 cm (9 species, e.g. Yamame, Mabuna, Sayori); averaged over all species it costs 0.2 mistakes you could otherwise afford. Price ¥500; sold in area 5 (special rod seller). For fish this line cannot hold, use Hera rod 3 m (¥200, areas 4, 5) or Carp rod 5 m (¥1,500, area 5). If you already own this rod, keep using it.

The numbers come from simulated fights: the rod sets the fight meter's starting point, which decides how many mistakes you can afford. This rod costs 0.2 mistakes per species on average (the best rod costs 0). Line strength decides how far a fish may run before the line breaks.

When should I choose this rod?

For big fish: line strength ×24 is long enough for every species; best start against 23 species; worse against fish up to 15 cm and fish of 16–35 cm (46 species)

Why and what to compare

Full recommendation

Line strength ×24 is how far a fish can run before the line breaks and the hook is lost. This rod is long enough for every species. It gives the best fight start against 23 of 72 species but is worse against fish up to 15 cm and fish of 16–35 cm (46 species, e.g. Haze, Suppon, Yamame); averaged over all species it costs 1.5 mistakes you could otherwise afford. Price ¥1,500; sold in area 5 (special rod seller). If you already own this rod, keep using it.

The numbers come from simulated fights: the rod sets the fight meter's starting point, which decides how many mistakes you can afford. This rod costs 1.5 mistakes per species on average (the best rod costs 0). Line strength decides how far a fish may run before the line breaks.

It is not sold in any of the six areas. For fish this line cannot hold, use the medium fly rod (¥400, areas 1, 2, 3, 5). If you already own this rod, keep using it.

A fly rod: line strength ×15 holds 30 of 33 species, and it gives the best fight start against 25 of them.

Line strength ×15 holds 30 of 33 species. The other 3 species (e.g. Aouo, Black bass, Nijimasu (rainbow trout)) run farther than that, so the line breaks and the hook is lost; they need a longer rod.
Fight start by fish size: this rod is best for 25 of 33 species and costs 0.2 mistakes on average.

Within Fly rods: time to aim ranks 3/3 at full HP; line strength ranks 3/3. Rank 1 is longest/highest in that dimension.

ROM price field: ¥350

At 100 HP the automatic aim cutoff is 50 counter ticks. The line range is 5040 internal position units (15 × 336), not meters: the game uses it to decide whether the fish was dragged past the line.
The fight meter's start is computed by the routine at 04:8D2A..8EC1 from the rod's class (selector 0), the fish's size and a matching fish ID. The measured effect is in docs/gear-effects.md.

When should I choose this rod?

For fish that line strength ×18 holds (30 of 33 species); best start against 20 species; worse against fish up to 15 cm (10 species)

Why and what to compare

Full recommendation

Line strength ×18 is how far a fish can run before the line breaks and the hook is lost. This rod holds 30 of 33 species; the other 3 species (e.g. Aouo, Black bass, Nijimasu (rainbow trout)) run farther, so they need a longer rod. It gives the best fight start against 20 of 33 species but is worse against fish up to 15 cm (10 species, e.g. Mugitsuku, Akaza, Oyanirami); averaged over all species it costs 0.4 mistakes you could otherwise afford. Price ¥400; sold in areas 1, 2, 3, 5. For fish this line cannot hold, use the large fly rod (¥450, areas 1, 2, 3, 4). If you already own this rod, keep using it.

For fish that line strength ×21 holds (30 of 33 species); best start against 9 species; worse against fish up to 15 cm and fish of 16–35 cm (22 species)

Why and what to compare

Full recommendation

Line strength ×21 is how far a fish can run before the line breaks and the hook is lost. This rod holds 30 of 33 species; the other 3 species (e.g. Aouo, Black bass, Nijimasu (rainbow trout)) run farther, so they need a longer rod. It gives the best fight start against 9 of 33 species but is worse against fish up to 15 cm and fish of 16–35 cm (22 species, e.g. Yamame, Bluegill, Gigi); averaged over all species it costs 1.7 mistakes you could otherwise afford. Price ¥450; sold in areas 1, 2, 3, 4. If you already own this rod, keep using it.

The numbers come from simulated fights: the rod sets the fight meter's starting point, which decides how many mistakes you can afford. This rod costs 1.7 mistakes per species on average (the best rod costs 0). Line strength decides how far a fish may run before the line breaks.
