Japanese Reel Model Codes Explained: LT, C3000, HG, XH and the Rest
A Japanese reel is not sold as "size 4000". It is sold as 24 CERTATE LT4000-XH. Every letter in that is a specification. Here is how to read Shimano and Daiwa codes, so you know how a reel will fish before you buy it.

Why a Japanese reel has a code instead of a name
A UK reel is usually sold as "size 4000". A Japanese-market reel is sold as 24 CERTATE LT4000-XH, and every part of that is doing a job. It is not marketing. It is a compact spec sheet, and once you can read it you can tell how a reel will fish before you ever pick it up.
This matters more for Japanese domestic market (JDM) tackle than for European-spec gear, because the JDM range is far wider. Shimano and Daiwa both sell shallow, standard and deep spools, and three or four gear ratios, in the same body. Two reels that look identical on a shelf can retrieve at speeds 30% apart.
Below is how to read both makers' codes, then a table you can keep, then three real reels decoded end to end.
How to read a Shimano reel code
Shimano codes run in this order: model year → family name → body/spool size → spool depth → gear ratio.
The two-digit year
A leading 21, 22, 24 is the model year of that generation, not the year it was made. "21 Ultegra" is the 2021 redesign, and it stayed in production for years afterwards. It is how you tell one generation from the next, because Shimano reuses family names for decades.
Size numbers
500, 1000, 2000, 2500, 3000, 4000, 5000, 6000, 8000 and upwards. Bigger number, bigger spool and more line. For UK fishing: 500–2000 for light rock fishing, 2500–3000 for bass and general lure work, 4000–5000 for heavier shore work, 8000 and up for shore jigging and big saltwater.
The C prefix
A C before the size means compact: a bigger spool fitted to a smaller, lighter body. A C3000 gives you 3000-size line capacity on a 2500-size body. This is one of the most useful things Shimano does and it is nearly invisible to buyers who cannot read the code.
Spool depth
Shimano marks spool depth with a letter before the gear code: SSS (special shallow), SS (super shallow), S (shallow), M (medium-deep), and no letter for the standard spool. Shallow spools exist because fine PE braid does not need 200 m of backing: a C2000S holds the right amount of 0.6 PE without wasting line or weight.
This is the one that catches people out. In a code like C3000MHG, the M is the spool, not the gear. It reads C body + 3000 size + medium-deep spool + high gear. There is no "medium high gear" ratio: the depth letter and the gear letters simply sit next to each other.
Gear ratio letters
- PG: Power Gear. Lowest ratio, most cranking power, slowest retrieve. Good for deep jigging and heavy lures.
- (no letter): standard ratio.
- HG: High Gear. Faster pickup, the most common choice for lure fishing.
- XG: Extra High Gear. Fastest; good for taking up slack quickly, harder work under load.
You may also see DH for a double handle. So a full code such as Stella C3000SDHHG unpacks as: Stella family, compact body, 3000 spool, shallow spool, double handle, high gear.
How to read a Daiwa reel code
Daiwa's modern spinning reels use the LT platform, and the code runs: model year → family name → LT → size → spool depth → gear ratio.
LT: Light and Tough
LT is Daiwa's since-2018 platform: a lighter body with a bigger, shallower spool ("Air Spool") and the Air Rotor. If a Daiwa reel says LT, it is on the current architecture. Some premium models such as the AIRITY and LUVIAS ST are also marked ST for the magnesium/carbon "super tough" body variants.
Size and spool depth
1000, 2000, 2500, 3000, 4000, 5000, 6000 as you would expect. Then the depth letter: S shallow, SS extra shallow, D deep, nothing for standard. So LT2500S is a shallow-spool 2500.
The C for compact
Daiwa also does the bigger-spool-on-a-smaller-body trick, marked with a C in the suffix. LT5000-CXH is a 5000-capacity spool on a compact body, with an extra-high gear ratio.
Gear ratio letters
- P: Power, lowest ratio.
- (no letter): standard.
- H: High gear.
- XH: Extra high gear.
QD: Quick Drag
QD means Quick Drag: roughly a single turn from slack to fully locked, instead of the usual several. Popular for trout and for anglers who want to change drag fast mid-fight.
Quick reference table
| Code | Maker | What it means |
|---|---|---|
| 21 / 22 / 24 / 25 | both | Model year of that generation |
| C (before size, Shimano) | Shimano | Compact body, larger spool |
| C (in suffix, Daiwa) | Daiwa | Compact body, larger spool |
| LT | Daiwa | Light & Tough platform (2018 onwards) |
| ST | Daiwa | Premium light body variant (AIRITY ST, LUVIAS ST) |
| S / SS | both | Shallow / extra shallow spool |
| D | Daiwa | Deep spool |
| PG / P | Shimano / Daiwa | Power gear: slowest, most torque |
| M | Shimano | Medium-deep spool: a spool depth, not a gear ratio |
| SSS | Shimano | Special shallow spool (shallower than SS) |
| DH | Shimano | Double handle |
| HG / H | Shimano / Daiwa | High gear |
| XG / XH | Shimano / Daiwa | Extra high gear: fastest retrieve |
| QD | Daiwa | Quick Drag: about one turn lock to loose |
Three real reels, decoded
SHIMANO 22 SOARE BB C2000SSPG
22 2022 generation · SOARE BB the light-game family · C compact body · 2000 spool size · SS super shallow spool · PG power gear. Read it out loud: a 2022 light-rock reel on a small body, with a very shallow spool for fine braid, geared low for control rather than speed. That is an ajing and LRF reel, and the code says so before you read a single review.
DAIWA 23 AIRITY PC LT3000-XH
23 2023 · AIRITY the premium light family · PC the custom variant · LT Light & Tough platform · 3000 size · XH extra high gear. A light, fast-retrieve 3000: a bass and seatrout reel.
SHIMANO 21 STRADIC SW 10000HG
21 2021 · STRADIC SW the saltwater family · 10000 big spool · HG high gear. Shore jigging and big saltwater, with enough line for a long run.
What the codes mean for common UK jobs
| What you are doing | Look for |
|---|---|
| LRF / ajing / light rock | Shimano C2000S or 500–1000; Daiwa LT1000S–LT2000S. Shallow spool, standard or power gear. |
| Bass on lures from the shore | Shimano C3000HG or 4000; Daiwa LT3000-XH or LT4000-CXH. High gear helps you keep contact. |
| Perch and pike on soft plastics | Shimano C2500–C3000; Daiwa LT2500S. Standard or high gear. |
| Shore jigging | Shimano 8000–10000HG; Daiwa LT5000-CXH upwards. Big spool, high gear, strong drag. |
| Deep jigging with heavy metals | Power gear (PG / P). You want torque, not speed. |
One honest caveat: line capacity ratings are printed for the maker's own line and vary between families. Treat the size number as a class, not a promise, and check the spool rating on the individual product page.
FAQ
What does LT mean on a Daiwa reel?
LT stands for Light and Tough, Daiwa’s reel platform introduced in 2018. It combines a lighter body with a larger, shallower Air Spool and the Air Rotor. If a modern Daiwa spinning reel carries LT in the name, it is built on this platform.
What does the C mean in Shimano C3000?
C means compact. A C3000 puts a 3000-size spool on a smaller 2500-size body, so you get the line capacity of the larger reel at the weight and balance of the smaller one. Daiwa does the same thing but puts the C in the suffix, as in LT5000-CXH.
What is the difference between HG and XG on a Shimano reel?
Both are faster than the standard ratio. HG is High Gear and XG is Extra High Gear, which recovers more line per handle turn. XG picks up slack fastest, which suits fast lure work, but it is harder to wind under heavy load. HG is the usual all-round choice for UK lure fishing.
What does S or SS mean after a reel size?
S is a shallow spool and SS is shallower still. Fine PE braid takes up very little room, so a shallow spool holds the right amount without wasting line or adding weight. A Shimano C2000SS or a Daiwa LT2000SS is aimed at light braid for LRF and ajing.
Do the numbers at the start of the name mean anything?
Yes. A leading 21, 22, 24 or 25 is the model year of that generation, not the year the reel was made. Shimano and Daiwa reuse family names for decades, so the year is how you tell a 21 Ultegra from an earlier one.
What is QD on a Daiwa reel?
QD is Quick Drag. The drag goes from fully slack to fully locked in roughly one turn of the knob instead of several, so you can change drag pressure quickly during a fight. It is common on trout models.
Are JDM reel sizes the same as European sizes?
They use the same numbers but the Japanese domestic range is much wider, with shallow, standard and deep spools and three or four gear ratios in the same body. A European-spec reel is often sold in one configuration where the JDM version has six.
What does MHG mean on a Shimano reel?
It is two codes running together. The M is the spool depth (a medium-deep spool), and HG is High Gear. So a C3000MHG is a compact body with a medium-depth 3000 spool and a high gear ratio. There is no "medium high gear" ratio in Shimano’s system; the depth letter simply sits in front of the gear letters.
