As was already mentioned, the International Military Tribunal for the Far East tried Japanese citizens for war crimes and the like. Some more information on the tribunal:

• The Tribunal was established on January 16, 1946, and convicted 28 accused Japanese war criminals in November of 1948.

• The crimes were similar to those established by Nuremberg: crimes against the peace, crimes against humanity, and war crimes.

• The court considered (the initial indictment had 55 counts, only 10 counts were left by the end), and convicted, on the counts of: conspiracy to wage aggressive war, the waging of that war against China, the US, British Commonwealth, Netherlands, France, USSR, and Mongolian People's Republic, conspiracy to violate the laws and customs of war, and reckless disregard of duty in failure to prevent breaches of the laws and customs of war.

• The judgment had nine of eleven tribunal members concurring, and put blame on the Japanese army and Japan in general for waging aggressive war.

• One defendant was not charged because of insanity. Two died of natural causes during the trials. Seven were hanged, on December 23, 1948. Sixteen were given life imprisonment. Only one managed to get seven years imprisonment.

• India's judge exonerated the defendants, and France's judge called for acquittals, saying the blame should be laid at the feet of Emperor Hirohito (who did not stand trial). The court's other justices (with the exception of Australia's and the Philippines' judges, who wrote separate opinions) concurred in their opinions. The judge from the Netherlands argued for more leniency in his dissent for some of the accused.

The above are also called the "Tokyo Trials". There were other trials, however, and far more people indicted and convicted than those 28. As the 1945 Yalta Conference declared:

The conference agreed that the question of the major war criminals should be the subject of inquiry by the three Foreign Secretaries for report in due course after the close of the conference.

This, coupled with the 1943 Moscow Conference precedent for Germany, provided the precedent needed (as if Nuremberg wasn't enough) to try Japanese war criminals outside of the leadership.

The trials dealing with these "lesser criminals" (known as Class B and C criminals) were known as the "Yokohama War Crimes Trials", and were prepared for to great extend. From March of 1945, a War Crimes branch was created by the United States, and lists of suspects and cases were compiled. The moment hostilities were terminated, incarcerations took place as quickly as humanly possible. On December 6, 1945, General MacArthur ordered the appointment of military commission for the trials on war crimes, which were ordered to start immediately. The Legal Section for the Supreme Commander for the Allied Powers expected 300 trials involving 500 or more people would be held, and by May of 1950 there were over 952 people who had been tried, with 33 accused still on trial at that date. 996 would be tried total. Many prisoners had given themselves up voluntarily when their names were published on war crimes lists, and 200 were confined in Sugamo prison when the trials began.

The first commission convened on December 17, 1945, with nine high-ranking officers appointed to it. They established the precedents for the later trials to come. There weren't many who escaped notice, truth be told. As the Chicago Daily Tribune noted on September 17, 1945:

Japanese militarists crowded Yokohama prison today, and with the arrest of Shigenori Togo, who as foreign minister helped plunge his nation into war, the manhunt for the main war criminals suspects was nearly ended.

The Yokohama trials weren't the only ones to take place, however. All in all, the Pacific saw over 2,000 trials and 5,000 defendants, divided into categories based on whether or not they committed crimes against the peace and how severe their other crimes/positions were. At Yokohama, of the 996 tried, 854 would be convicted, and 124 were given death sentences (only 51 would be carried out as some sentences were reduced). 63 were sentenced to life imprisonment, 2 to 41-50 years, 410 would be given between 6 and 40 years, and the rest (255) got less than 5 years.

Other trials took place in China, the Philippines, and other areas for lesser criminals. Unlike the case of Israel and Eichmann, there was no high-profile leader on the run, and the leaders were summarily caught and handled much more quickly. There are some who undertake "Nazi hunting" on their own, but as far as I've seen there's no comparable effort by the Chinese or United States to track down Japanese war criminals, nor has there been much focus on it. The Nuremberg Trials overshadowed the Tokyo Trials by quite a bit, and because the Tokyo Trials dealt with all Class A criminals (the ones people at the time cared about, to be brutally honest), there was less incentive to go after any other Class B or C criminals, though some argued that the Japanese Princes (some, anyways) and Emperor should've been tried. But because the Yokohama and other trials were overshadowed by both Nuremberg and Tokyo, it's hard to find much on them and harder to imagine anyone going after Class B or C criminals well after the war ended, besides to very small degrees and the kind of degrees that don't get much notice.

Something kind of related that I don't know how many people know about was that large Japanese companies used American POWs as slave labor during the war. The conditions were brutal and many Americans died from unsafe conditions, malnutrition and violence from guards/foremen. After the war the American government refused to allow POWs to sue for reparations. Many of the companies which used slave labor are still around today.

I don't know if sources need to be academic but mine is my grandfather's memoir about his time as a POW. He was captured on Corregidor and spent almost the entire war as a POW being forced into slave labor for much of the time. While he didn't hold animosity towards the Japanese people he refused to ever buy products from several Japanese companies due to his experiences.
