Netherlands Indies (modern day Indonesia) was formally established as a Dutch Colony in 1800 when it took the islands from the Dutch East India Company. Over the years, the resource rich colony expanded and flourished, but typical with colonial systems, the local population were exploited by their rulers. The colony, spread over more than tens thousand islands often experienced rebellions and resistance to colonial rule.

Far to the north of the colony, the every expanding Japanese Empire was advancing on the Chinese Mainland. Eventually, World War 2 broke out in the pacific as Japan attacked Pearl Harbor and other Allied ports in the Pacific in Dec, 1941. The Netherlands declared war on Japan on Dec 8th, shortly after those attacks. The Netherlands, ruled by a government in exile in London, was already under Nazi occupation in Europe. Continuing to the south, the Japanese invasion of the Dutch Indies began on Jan 10th, 1942 on Borneo. Dutch forces in the Indies along with the Americans, British, and Australians, were unable to hold back the Japanese war machine, and eventually surrendered on March 8th, 1942.

Initially, the Japanese were seen as potential liberators by the local population, as Sukarno, a popular Indonesian nationalist leader supported the Japanese occupation. However, the Indonesians soon discovered that Japanese rule was even harsher, as many were conscripted into forced labor while food and materials were shipped off of the islands to support the war effort. Additionally, more than 100,000 European, Chinese and other western people were held in internment camps, where many eventually died of starvation.

During the occupation, the Japanese divided the colony into three separate regions. Java, administered by the Japanese 16th army, Sumatra administered by the Japanese 25th army, and the outer islands called Borneo and the Greater East which was administered by the Japanese navy.

For Sumatra and the Greater East, the primary goals of the occupation was to maintain law and order, and to extract the valuable resources available in the region. In Sept, 1942, the Japanese placed Sumatra under the same administration as Malaysia, but this only lasted 6 months, when it was returned to a separate administration.

The occupiers took food and vital materials from the region, causing widespread starvation among the Indonesians. Forced conscription of locals to work in defense related projects was common practice. Many of the laborers (romusha), were also sent to the outer islands and other Japanese occupied regions to work on various wartime construction projects.

In the last few months of the war, the Japanese promoted the independence moment, to frustrate the ability of the Allies to re-occupy the islands. Eventually, the Japanese surrendered to the allies on August, 15, 1945, but Sukarno immediately declared an independent Indonesia. This resulted in a 4 year civil war against the Dutch, eventually, leading to an independent Indonesia, established in 1949.

Stamps

FE - Sumatra, Japanese Occ StampALBUM

During the occupation, the Japanese divided the colony into three separate regions. Java, Sumatra, and the outer islands called Borneo and the Greater East. Each ran their own postal authorities and issued their own stamps. For the first year of occupation, Netherlands Indies stamps, except those featuring Queen Wilhelmina, were used.

Sumatra was placed under the Japanese 25th army, and both local and regional postal authorities overprinted with various designs of pre-war stamps from the Dutch Colony. More than 50 different overprints have been identified, with a multitude of local varieties. Since these were locally and regionally applied, there are a huge variety of overprints. Identifying the various overprints can be very complicated, therefore specialized materials, such as those published by Dai Nippon is required. During the 6 month attachment to Malaysia, Sumatra used occupation stamps from the Malay States.

On April 29th, 1943, the Japanese authorities issued a set of attractive definitive stamps for Sumatra. The 12 denominations featured 5 different designs with scenes specific for the island. All of the stamps were denominated in Dutch currency, except the highest denomination, which was 1 roepiah, the currency introduced by the Japanese.

Banknotes

While postal authorities and administration differed during the Japanese occupation, the control of banking and currency was much more centralized. After the occupation was complete, Japanese authorities liquidated all of the banks and voided all debts. New banknotes, inscribed “Japansche Regeering”, or Japanese Government were printed and issued by the Japanese government beginning March, 1942. The new notes denominated from 1 cent to 10 gulden were expected to be exchanged 1:1 with the former Dutch currency.

While the goal of the Japanese was to over time replace the Dutch Indies currency, pre-occupation currency remained as legal currency. It soon became apparent that the invaders printed far too much currency, causing rampant inflation of the Japanese currency. As a result, people hoarded the Dutch Indies currency, and replacement never happened.

Two years into the occupation, the Japanese began to encourage the growth of Indonesian nationalism, because they believed that local government was in their own strategic interests. In 1944, the Japanese issued a second set of notes in Javanese and printed in Java which was denominated in Roepiah. The notes ranged from 1 – 10 roepiah.

In addition, two additional notes (100 and 1,000 rupiah) were printed in Japan for exclusive use in Sumatera. The circulation of these notes are doubted by some experts.
