It was a routine basis thing with strong religious overtones. It started in China when Japanese troops were encouraged by their officers to eat parts of the bodies of Chinese soldiers (and to kill Chinese PoWs specifically so that their body parts could be eaten). It spread from there until it was commonplace throughout the Imperial Japanese Army and it long predated the point in WW2 when isolated garrisons were cut off by the American advance. For many years, it was covered up, not least because U.S. authorities in particular didn't want to tell the immediate families that their sons/husbands had been killed and eaten.
The religious aspect to this can be illustrated by the fact that very often the liver was cut out of the victim (very often while said victim was still alive), cooked and shared out in small portions across a unit while the rest of the body was unceremoniously dumped. Obviously, had the cannibalism been the result of starvation, most or all of the body would have been eaten. A well-documented case occurred in Chichijima in February 1945, when Japanese soldiers killed and consumed five American airmen. This case was investigated in 1947 in a war crimes trial, and of 30 Japanese soldiers prosecuted, five (Maj. Matoba, Gen. Tachibana, Adm. Mori, Capt. Yoshii, and Dr. Teraki) were found guilty and hanged. During his trial, Major Matoba described a number of occasions on which the flesh of murdered prisoners of war was consumed in the Japanese officers' mess. This took on the character of a festive occasion, with the flesh being washed down with sake. Very senior army and navy officers attended the officers' mess when human flesh was consumed and they encouraged this behaviour.
In his book
Flyboys: A True Story of Courage, James Bradley details several instances of cannibalism of World War II Allied prisoners by their Japanese captors. This included not only ritual cannibalization of the livers of freshly-killed prisoners, but also the cannibalization-for-sustenance of living prisoners over the course of several days, amputating limbs only as needed to keep the meat fresh.
In New Guinea, there is an abundance of easily grown natural foods, including paw paw, coconut, and various types of sweet potato. Cannibalism was, however, widespread amongst Japanese troops serving in New Guinea with numerous recorded cases of Australian troops finding bodies of captured personnel having been butchered for meat. 'Toshiyuki Tanaka, a 43-year-old scholar from Fukui in western Japan, working at the Political Science Department in Melbourne University found documents concerning cannibalism include captured Japanese army memos as well as sworn statements by Australian soldiers for war crimes investigations. Mr Tanaka says he has amassed at least 100 documented cases of cannibalism of Australian and Indian soldiers as well as Asian forced labourers in New Guinea. He has also found some evidence of cannibalism in the Philippines.'
'In some cases the (Japanese) soldiers were suffering from starvation, but in many other cases they were not starving at all,' said Mr Tanaka. 'Many reports said the Japanese soldiers were fit and strong, and had potatoes, rice and dried fish.' The researcher also denied it was a result of a breakdown in morale: 'The reports said morale was good. Often it was done in a group under instruction of a commander. I think it was to get a feeling for victory, and to give the soldiers nerves of steel.' He said it helped the soldiers to bond 'because the whole troop broke the taboo (of cannibalism) together' (

In fairness, it should be noted that some Japanese officers strictly forbade the practice of cannibalism in their units. The commander of the 41st infantry division issued an order on November 18 1944 stating that any soldier found eating human flesh would be summarily executed. Of course, the very fact that such an order had to be issued is indicative of the scale of the problem.
A google search for cannibalism "Japanese Army" will give you all the sources you need. In addition, I strongly recommend the book highlighted above.
