The IJF World Ranking List is not a monthly or quarterly publication — it is a living document that recalculates after every sanctioned competition and reflects changes that happen on multiple timescales simultaneously. New results add points immediately. Old results begin decaying at precisely defined moments. The combination of ongoing event results and built-in point decay means the ranking shifts not just after tournaments but on every Monday of the year, as tournament-week calculations advance. Here is exactly how and when the IJF ranking list changes.
- The IJF World Ranking is updated after every sanctioned tournament and published on the IJF website within days of each event.
- Rankings also shift each week as the 12-month full-value period and 24-month expiry windows advance — even without any competition taking place.
- The IJF uses tournament weeks, not calendar dates, to track when points were earned — decay triggers at the start of the matching week the following year.
- A significant weekly update occurs during the first week of each new month when points from events that wrapped up exactly 12 or 24 months prior begin decaying or expiring.
- The ranking is downloadable from the IJF website at any time, with individual athlete positions updated in real time.
When the Ranking List Is Updated: After Every Event and Every Week
The IJF World Ranking uses a continuous rolling calculation rather than a fixed publication schedule. Two types of updates occur independently: result-driven updates and time-driven updates. Result-driven updates happen when a new sanctioned event completes — points earned at that event are added to the ranking totals of all competing athletes, and the resulting position changes are published on the IJF’s World Ranking List page within a few days of the competition’s conclusion. Time-driven updates occur on a weekly basis as the tournament-week tracking advances, triggering point reductions for results that have crossed the 12-month threshold and point expiries for results that have crossed the 24-month threshold.
Result-driven updates: after each competition closes
Every IJF-sanctioned event — from Grand Slams to Continental Opens — generates a batch of new ranking points when it concludes. For Grand Slams, Grand Prix, the World Championships, World Masters, and Continental Championships, these points include both placement awards (gold, silver, bronze, 5th, 7th) and participation points for all entered athletes, even those who lost their first contest. After the event concludes, the IJF processes all results and publishes an updated ranking list. The timeline between competition end and ranking update typically runs between 24 and 72 hours for major World Tour events. The IJF’s 2025 cycle announcement notes that ranking positions are recalculated on the basis of each athlete’s eligible results at that moment in time, meaning every new event immediately shifts positions across the entire field, not just for athletes who competed.
Weekly updates: decay and expiry without any competition
Less obvious but equally important is the fact that the ranking shifts weekly even when no competition is being held. The IJF tracks when each result was earned by tournament week — specifically, points decay begins at the start of the equivalent calendar week in the year following the event. If the Paris Grand Slam runs in the first week of February in one year, the points from that result begin their 50% reduction at the start of the first week of February the following year, regardless of whether Paris has yet been held that year. This tracking is precise to the week, which means on any given Monday during the competitive year, some results somewhere in the ranking system are either crossing their 12-month threshold (dropping to 50% value) or their 24-month threshold (expiring completely). The ranking total for every athlete with results near these boundaries changes automatically — no new competition required.
How frequently the ranking moves in practice
During the densest periods of the competition calendar — particularly the spring sequence when multiple Grand Slams run in consecutive weeks — the IJF ranking can change after every weekend. Between competitive periods, the ranking still shifts weekly as old points decay. In practice, anyone tracking the ranking closely will observe meaningful position changes multiple times per month. For athletes near critical thresholds — the top-17 cutoff for Olympic qualification, the top-36 threshold for World Masters invitation, or the top-100 requirement for World Championships entry — a routine weekly decay event without any competition can be enough to move them above or below a qualifying line. This weekly granularity is what the IJF means when it describes the ranking as a “rolling” system rather than a periodic publication.
How Tournament Weeks Determine the Timing of Decay
The IJF uses a tournament-week model rather than a precise date model for tracking point lifespans. This distinction matters for athletes and coaching staff who need to predict exactly when results will change value. A result from a Grand Slam held during week 7 of 2025 begins its decay at the start of week 8 in 2026 — not on the exact anniversary date. The week-based system avoids complications from calendar irregularities and ensures consistency across events that may fall on slightly different dates from year to year.
The 12-month threshold: when full points become half points
Full-value points — at 100% of face value — count from the moment they are earned until the start of the matching tournament week in the following year. At that moment, the points are cut to 50% of their original value. A Grand Slam gold earned in year one at 1,000 points becomes a 500-point result the following year at the corresponding week. This reduction applies to every result simultaneously: gold, silver, bronze, and participation points from the same event all halve at the same week-start trigger. Athletes competing at the same events year over year are in a continuous state of defending their full-value points against this automatic decay — winning the same event again replaces the decaying prior result with a fresh full-value result, maintaining the ranking contribution from that event.
The 24-month expiry: results disappear from the ranking total
At the start of the tournament week that matches the event exactly two years prior, points expire completely and contribute zero to the ranking total. An athlete’s ranking total on that week effectively drops by the 50% value that was still counting. For athletes whose ranking is constructed heavily from results earned near the two-year boundary — particularly useful for athletes who had a strong year two years prior but have since competed less — these expiries can cause sudden visible ranking drops with no corresponding defeat in the current competitive season. The expiry happens mechanically based on the calendar, not as a result of any competitive event.
How the six-result cap interacts with weekly updates
Under the six-result cap introduced in January 2025, each athlete’s ranking total uses their six best results from any 12-month period. When a result decays from 100% to 50% at the 12-month trigger, the six-result selection algorithm reruns: if the decayed result still ranks among the athlete’s six best in the current window, it counts at 50%; if a different result now scores higher than the decayed one, the algorithm may substitute it. This reselection happens automatically and can produce counterintuitive ranking movements — an athlete might actually improve their position at the 12-month decay trigger if the reselection pulls in a previously uncounted result that outperforms the decayed one.
Where to Find the Current Ranking and How to Read It
The IJF publishes the World Ranking List at ijf.org/wrl, accessible by weight category and age group. Individual athlete pages show their current total points, their position within the weight class, and the events contributing to their ranking. The IJF also publishes downloadable ranking documents for each weight category, updated following each major event. The Olympic Ranking List — a separate but related list used specifically for Olympic qualification — is published at a different URL and applies the same underlying data with the additional one-per-NOC constraint applied.
IJF World Ranking vs Olympic Ranking List: two different documents
Two separate ranking lists matter for athletes. The IJF World Ranking (WRL) is a pure points-based ranking with no nationality restrictions — if two athletes from the same country rank 1st and 3rd in a weight class, both appear at those positions. The Olympic Ranking List (ORL) applies the one-per-NOC filter: only the highest-ranked athlete from each country appears per weight class, collapsing all remaining athletes from that country downward. This means an athlete’s WRL position and ORL position can differ significantly — a judoka ranked 8th in the WRL might appear considerably higher in the ORL if several athletes ranked above them share a nationality with each other. Both lists are updated on the same schedule as described above, but the ORL recalculates the filtered positions as part of each update cycle.
During events: real-time results vs official ranking
During an active Grand Slam or Grand Prix weekend, the IJF publishes live results through the Judobase platform and the IJF app. However, the official ranking list is not updated in real-time during an event — it is recalculated and published after the event concludes. Provisional standings can be estimated based on the points a result would contribute, but the official ranking incorporating the new results is the version published post-event. This matters for athletes monitoring their position relative to a qualifying threshold: the ranking they see on Friday of a Grand Slam weekend does not yet include that weekend’s results, even if those results are known by Saturday night.
Frequently Asked Questions
How long after a Grand Slam does the IJF update the rankings?
The IJF typically updates and publishes the World Ranking List within 24 to 72 hours after a Grand Slam concludes. The exact timing varies but is consistently within a few days of the competition’s final day.
Does the ranking change even when there are no competitions?
Yes. The ranking changes every week as the 12-month and 24-month decay windows advance. Results from events held exactly one or two years ago change value automatically at the start of the matching tournament week, shifting all affected athletes’ totals without any new competition occurring.
Can my ranking drop without losing a match?
Yes. If points from a result earned 12 months ago drop to 50% value at the weekly trigger, your ranking total decreases by the difference, and athletes below you who had more stable recent results may pass you. Similarly, when a strong result expires at 24 months, your ranking drops by its full remaining 50% value.
Where can I check the current IJF world judo ranking?
The IJF publishes the current World Ranking List at ijf.org/wrl, filterable by weight category and gender. The Olympic Ranking List — used for Olympic qualification — is at ijf.org/wrl_olympic. Both are updated after each sanctioned event and recalculate automatically each week based on the point decay schedule.
