Pick the update you stopped at. This page shows what came after it, and admits which stretch of the patch history I could not verify instead of filling it in.
Most of this site's guides were written for Update 24, the week the game launched. The roster has moved on since then, and this is the one page built specifically to close that gap instead of assuming everyone reading is still on Update 24.
Select the update number you were last on. The list below filters to only what happened after it, so you are not re-reading patch notes you already lived through.
The fullest patch note in the entire record. Verbatim: ADDED DESTOROYAH FLY FORM, ADDED SHOWA GHIDORAH, ADDED SHOWA MOTHRA, ADDED GOJIRA 1964, ADDED X2 EXP, BEAM CLASH, LIMIT BREAK. This is the only official mention of beam clash or limit break anywhere.
Full guide →ADDED GOROSAURUS. The archive has no capture between 2026-05-27 and 2026-06-16, so this could have shipped anywhere in that window.
ADDED MINILLA, plus three balance lines: attacking while flying was fixed, max flight speed was cut from 45 to 37, and air attack cooldowns went up. This is the one and only update where the developer published actual numbers.
ADDED MONSTER X. Nothing else. If you have read elsewhere that this update also added Queen MUTO or buffed Godzilla 2019, that is not in the official text.
ADDED SHOWA JET JAGUAR. Its abilities and unlock cost have never been documented by anyone.
No capture of the description survives for Update 38. What does survive is the official place name, which read Final Wars Godzilla on 2026-07-15, four days before Showa Gigan and Update 39 appeared. So Final Wars Godzilla was live by then and 38 is the likely number, but the pairing is an inference and not something the developer stated.
ADDED SHOWA GIGAN. Still the live update as of 2026-07-28, which makes this the longest run without a new release since the record begins. Its stats and unlock cost are undocumented.
This is the same update schedule the tracker above filters, laid out as one reference table. Details on each entry are one section up once you pick a starting point; the Update 24 and 25 log has the long-form patch notes and meta analysis for the launch window.

SULU KAKA does not publish patch notes. What they do instead is overwrite the game's Roblox description with a line like NEW UPDATE 39 and ADDED SHOWA GIGAN, and rename the place itself to whatever kaiju headlines the release. Both of those are official, and both get captured by the Internet Archive. So the archive is the only machine-verifiable patch record this game has, and the table above is built from it rather than from other guide sites.
That method has a hard ceiling. The description is overwritten in place, so if the archive happened not to capture the page during an update's run, that update's contents are gone for good. Updates 22, 23, 26, 27, 29, 30, 33, 34, 35, 36 fall in those blind spots. That is not a gap I can close by searching harder, and it is not one I will fill with guesses.
For the live Roblox game-page status and an explanation of why archive observations cannot provide a schedule, see the Kaiju Alpha next update tracker.
Even where a description capture is missing, the archived page title often is not. Because the developer renames the place to the headline kaiju, each archived name is official proof that a kaiju was live by that date. It carries no update number, so it cannot fill the table above, but it does tell you roughly when things arrived.

Two things worth reading off that list. The x1.5 Coin, X2 EXP and X2 XP entries are timed events the developer ran, not anything you can buy, which matters because several guides describe them as purchasable passes. And Showa Gigan has held the title since 2026-07-19, the longest stretch without a new release anywhere in this record.
If you kept a screenshot of the in-game changelog from one of the undocumented stretches, the contact page is open. That is the one thing that would actually close those gaps.
They are observed-live-by dates from Internet Archive captures, never release timestamps. The archive can miss releases between captures, so the record documents confirmed historical observations rather than a complete schedule or cadence.
The separate Kaiju Alpha Next Update page checks the current official Roblox game-page metadata and explains why it does not infer a release schedule. This tracker remains a retrospective record of confirmed additions and their provenance.
Showa Gigan, in Update 39. That comes straight from the official game description. Before it, Final Wars Godzilla was live by 2026-07-15 and Showa Jet Jaguar arrived in Update 37. What none of them have is documented stats or unlock costs. The developer has never published any, and no creator has measured any, so anything you read describing their abilities in detail is somebody guessing.
Nobody can answer that honestly. SULU KAKA has not published its stats, no creator has measured them, and a tier placement without either would be a guess dressed up as an answer. What is on the record is that flight got harder for everyone in Update 31: attacking while flying was fixed, max flight speed was cut from 45 to 37, and air attack cooldowns went up. That is the only balance change the developer has ever put a number on, and it landed before Jet Jaguar arrived.
Because the record they would come from no longer exists. SULU KAKA publishes each update by overwriting the game description, so the previous note is destroyed every time a new one goes up. The Internet Archive is the only thing preserving those notes, and it did not happen to capture the page during updates 22, 23, 26, 27, 29, 30, 33, 34, 35 or 36. Searching harder does not help. Filling the gap with plausible-sounding patch notes would, and that is exactly what several other sites have done.
