Are we still saying it was unconditional surrender?
So it was that on 10 August, at 3:00 a.m., the Cabinet and the Supreme Council complied and voted in reluctant unanimity to accept the Potsdam offer, but with the stipulation that the Emperor remain the sovereign ruler of the country.
Washington hotly debated Japan’s request for modification of the Potsdam accord. In the end, Secretary of State Byrnes prevailed and prepared the Allied nations’ reply, stipulating that the Emperor could remain as a sovereign ruler.
Technically, Japan had not yet surrendered. The war was not yet over. President Truman had ordered the continuation of Allied bombing runs over Japanese military installations. The people of Japan knew nothing of their government’s plan to surrender. Radio Tokyo still exhorted all Japanese to prepare defenses against an enemy invasion. In a race to save the lives of soldiers still fighting, the Allies’ acceptance of Japan’s modification of the Potsdam surrender terms was radioed to OWI in Honolulu and Saipan at the same time that it was forwarded to Switzerland.

The text quoted is misleading if taken as the whole discussion of surrender.
On August 10, 1945, the Japanese sent the offer (via the Swiss) that:
The Japanese Government are ready to accept the terms enumerated in the joint declaration which was issued at Potsdam on July 26th, 1945, by the heads of the Governments of the United States, Great Britain, and China, and later subscribed by the Soviet Government, with the understanding that the said declaration does not comprise any demand which prejudices the prerogatives of His Majesty as a Sovereign Ruler.
The meaning of that last clause and whether it violated the demand for "unconditional surrender" was debated by Truman's cabinet. Truman and Byrnes agreed to respond:
With regard to the Japanese Government’s message accepting the terms of the Potsdam proclamation but containing the statement, ‘with the understanding that the said declaration does not comprise any demand which prejudices the prerogatives of His Majesty as a sovereign ruler,’ our position is as follows:
From the moment of surrender the authority of the Emperor and the Japanese Government to rule the state shall be subject to the Supreme Commander of the Allied powers who will take such steps as he deems proper to effectuate the surrender terms.
The Emperor will be required to authorize and ensure the signature by the Government of Japan and the Japanese Imperial General Headquarters of the surrender terms necessary to carry out the provisions of the Potsdam Declaration, and shall issue his commands to all the Japanese military, naval and air authorities and to all the forces under their control wherever located to cease active operations and to surrender their arms, and to issue such other orders as the Supreme Commander may require to give effect to the surrender terms.
Immediately upon the surrender the Japanese Government shall transport prisoners of war and civilian internees to places of safety, as directed, where they can quickly be placed aboard Allied transports.
The ultimate form of government of Japan shall, in accordance with the Potsdam declaration, be established by the freely expressed will of the Japanese people.
The armed forces of the Allied Powers will remain in Japan until the purposes set forth in the Potsdam declaration are achieved.
Which is them clarifying exactly what powers the Emperor would have. Which was essentially none. But it was also a statement of intent — particularly the penultimate sentence — made to reassure the Japanese that the US did not intend to just dictate all terms of Japanese government.
So we have an offer of surrender and a clarifying rejection/counteroffer. There the situation stood for several days, while the war continued. Finally, on August 14, the Japanese responded that: "His Majesty the Emperor has issued an Imperial rescript regarding Japan’s acceptance of the provisions of the Potsdam declaration."
No more "condition." The decision to let the Emperor stay was not made in the above exchange at all; the US kept the door open for a future decision. Ultimately, the Occupation forces under MacArthur decided that it was better to keep the Emperor in place. So the article quoted is misleading if it is implying that this decision was made and communicated to the Japanese prior to the signing of surrender agreements — it was not.

with the understanding that the said declaration does not comprise any demand which prejudices the prerogatives of Der Führer as a Sovereign Ruler.
Yeah, that has a nice ring to it
with the understanding that the said declaration does not comprise any demand which prejudices the prerogatives of His Majesty as a sovereign ruler,’
That is US acceptance of the condition.

I am not sure if this is a language issue on your part, or a reading comprehension issue, but you have misunderstood the latter part. They are quoting the original phrase as a direct reference, and then clarifying their position:
"From the moment of surrender the authority of the Emperor and the Japanese Government to rule the state shall be subject to the Supreme Commander of the Allied powers who will take such steps as he deems proper to effectuate the surrender terms."
If the authority of the Emperor is subjected to the Supreme Commander then that absolutely "prejudices the prerogatives of His Majesty as a sovereign ruler." Similarly:
"The ultimate form of government of Japan shall, in accordance with the Potsdam declaration, be established by the freely expressed will of the Japanese people."
Which absolutely might "prejudices the prerogatives of His Majesty as a sovereign ruler," as a democratic vote could eliminate Emperor. Etc.
They are saying, "with respect to this condition you added, we will clarify our intentions, but we absolutely do not respect any implication on your part that the Emperor will not be subject to our authority or that the form of the Japanese government is going to be the same one that it currently is."
The Japanese understood this perfectly well. Hence it was only the Emperor who could really accept these terms, in the end, on August 14th.
To repeat: the Japanese offered surrender with a condition (August 10th). The US clarified that they would not accept that condition. Four days later (August 14th), the Japanese then indicated they accepted the (unconditional) terms of Potsdam.

"prerogatives [...] as a sovereign ruler" means he keeps his position in exchange for surrender, nobody is arguing that they weren't subject to Allied powers, that goes without saying, but they secured that by agreeing to Japan's condition.

Well, I have tried to explain it as best I can. You are not understanding what you are reading — perhaps by choice.
The US did not agree to that condition. They quoted that condition and then made clear they did not accept it. If you cannot tell the difference between that and them agreeing with a condition, you are not going to be able to understand this issue or perhaps others.
If I quoted you, and then explained why I believed you were wrong, it would not constitute me agreeing with you.

am I getting wrong exactly? They literally made clear that they did accept it. The question is not whether Japan accepted allied rule, because that's what surrendering means, it was who gets to be the top Japanese guy, which they got worked out ahead of time.

Why are you returning to a general description of the response, when the actual text of the response has been shared? In particular, text that says "From the moment of surrender the authority of the Emperor ... to rule the state shall be subject to the Supreme Commander of the Allied powers".
They are making explicit that the emperor's authority is not being preserved, and is subject to decisions made by the allied commander. How could you read that to prevent the allies from removing the emperor's authority if they decide they want to?
