Quick Answer
How should I check whether an NPB player can move to MLB through the posting system?
Start with MLB's Japanese Posting System glossary, then confirm the player's NPB team, active-player context, club announcement, and MLB transaction status. NPB Dashboard does not decide whether a player is posted, eligible, signed, retained, or subject to a specific release fee, salary, contract value, or bonus-pool limit.
- Posting, international free agency, and bonus-pool treatment depend on official MLB/NPB rules, player status, age, service time, and club decisions.
- Contract values, release fees, salary escalators, options, and signing bonuses can change through official transactions and contract terms.
- This page does not provide legal, tax, agency, scouting, betting, fantasy, contract-negotiation, or financial advice.
NPB posting system official-source checklist
This page is a source-check guide. It does not replace official MLB or NPB rules, club announcements, player contracts, agent communications, transaction logs, salary reporting, or legal advice.
| Question | Source | What to verify |
|---|---|---|
| Posting-system definition | MLB Japanese Posting System glossary | Use the MLB glossary for current posting-system definitions, player eligibility framing, negotiation window, release-fee treatment, and bonus-pool caveats. |
| Current NPB team and home-club context | NPB official English team index | Confirm the player's current NPB club, league, team site, roster context, and official NPB navigation before reading transfer rumors. |
| Current active-player context | NPB Register: Players Active in the NPB | Use the official NPB register to confirm whether a player is listed in current NPB player data before interpreting posting, free-agency, or roster reports. |
| Release-fee protocol history | MLB clubs ratify new posting system agreement with NPB | Use the MLB protocol announcement for the 2018 effective framework and release-fee terms, then verify whether newer league documents or announcements supersede it. |
| Earlier posting protocol context | MLB and NPB reach posting-system agreement | Use the 2013 protocol article only as historical context; do not treat its old window, fee cap, or process details as current unless a current official source says so. |
| International bonus-pool status | MLB international amateur free agency and bonus-pool glossary | Check the MLB bonus-pool glossary when age, foreign-professional status, signing bonus limits, or amateur/professional treatment affects a Japanese player's MLB path. |
| Current MLB transfer rumor context | MLB NPB/KBO players to watch for MLB in 2026 | Use current MLB reporting only as news context for named players; final posting, signing, contract, and roster outcomes require official transaction confirmation. |
How to read posting, salary, and contract data safely
Use dashboard pages to identify the NPB team, season context, schedule, and standings. Do not use this site as proof of player availability, contract value, salary, release fee, posting consent, or MLB signing status.
| Topic | Current dashboard role | Official check |
|---|---|---|
| Player and team context | NPB Dashboard can help users move from teams, schedules, standings, and current game context to official NPB or team pages. | Official NPB, team, MLB, and transaction sources decide whether a player is posted, signed, transferred, retained, or eligible for another pathway. |
| Contract values and release fees | This dashboard does not calculate live release fees, predict contract values, verify salary reports, or provide legal, tax, agent, or negotiation advice. | Use official MLB transaction guidance, league announcements, club releases, and primary contract reporting for final values and fee treatment. |
| Posting window and negotiation status | Dashboard pages do not show live posting windows, 45-day clock status, bidding status, club negotiations, medical review, or agent communications. | Check MLB, NPB, club, and official transaction channels for date-sensitive posting and signing status. |
| Rumors and player watchlists | News links can help users understand why a player is being searched, but rumors are not proof of posting consent or a signed MLB contract. | Separate current MLB reporting from official transactions, and re-check primary sources before making financial or travel decisions. |
