About the Mizuno JPX-923 Tour

The Tour is the compact end of the JPX 923 family, a Grain Flow Forged cavity back for single-figure players rather than the game-improvement Hot Metal that carries the same number. Lofts are traditional — 34 degrees at the 7-iron, six weaker than the JPX 925 Hot Metal — and offset is uniform and tight, moving only 0.025 inches across the whole set. Mizuno announced the JPX 923 family in 2022 and the Tour and Forged models reached retail in February 2023.

Finding a used set

The Mizuno JPX-923 Tour ran from 2022 to 2025 and is no longer in production, so the used market is the only source. Search the used listings on eBay, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.

Data compiled from:

2nd Swing Golf specification table for the Mizuno JPX 923 Tour iron set (2ndswing.com) — supplied every loft, lie, length, offset and swing weight above, the Dynamic Gold 120 stock shaft and the 4-GW set makeup.
golf.com '5 things you need to know about Mizuno's new JPX 923 irons' and mizunogolf.com's JPX923 summary — Mizuno announced the JPX 923 family in 2022, releasing the Hot Metal models on 13 October 2022 and the Forged and Tour models at retail in February 2023. year_introduced uses the announcement year, so a JPX 923 Tour set bought new will often be catalogued as a 2023 model.
Note: bounce is omitted — the source table did not carry a bounce column. Confidence is medium.
Predecessor is the JPX-921 Tour, the previous compact players model in the JPX line (announced August 2020), which the JPX 923 family replaced on its 2022 announcement.
Status check, 29 September 2026: year_discontinued is 2025. Mizuno ended the JPX Tour line when it launched the Pro S-3 in January 2025 (golf.com); the S-3 is the functional rather than a named replacement.
