Japanese Invasion Money

When the Japanese had captured the Asian countries , thus began the process of Japanisation of the subjects of the occupied countries.The Japanese authorities set up governments in all territories and one of the first things they did was name changing which will be stated in the posts. And in all occupied territories they had designs for banknotes which will be used by the local population once they have become citizens of the Japanese empire.These banknotes would later become victim to inflation due t the uncontrolled printing of these notes by the Japanese authorities.Emperor Hirohito

These Japanese Invasion Money was officialy known as the Southern Development Banknotes was issued by the Japanese military authority.In February 1942, a law was passed in Japan to establish the Wartime Finance Bank and the Southern Development Bank.These institutions issued bonds to raise funds. The former had also loaned money primarily to military industries but also had loaned money to other ventures, including hydroelectric generators, electric power companies, shipbuilding and petroleum.
The latter provided financial services in the areas occupied by the Japanese military, and the Southern Development Bank notes were used as the one and only currency circulating. These banknotes were printed without control and whenever the Japanese authorities needed money to pay for whatever supplies they needed, they would resort to the printing machine to print banknotes. Amount of money in circulation in the occupied territories would increase from millions to billons.

Life became very hard as prices rose and rose until prices for the most basic items such as rice was too expensive for people who were poor.More on the Japanese invasion money(JIM) in the next posts.Below are the exchange rates for the Japanese invasion money for local currency.

1 Japanese Rupee=1 Burma rupee
1 Japanese Gulden=1 Javanese Gulden
1 Japanese Dollar=1 Malayan Dollar
1 Japanese peso=i Philippine peso
1 Indochinese Piastre = 0.976 Japanese Yen
1 Japanese yen=2 Japanese Oceanic Shillings

Japanese Invasion money of the Philippines

Flag of the Second Philippine Republic under the Japanese

The Philippines, an American possession in Asia obtained from the Spanish, changed hands once more in 1942, this time by the Japanese who were rapidly conquering countries in South East Asia. On 10 December, 1941 Japanese troops landed on Luzon. The Japanese overran Manila on 2 January, 1942
Japanese Bombing of Corregidor

In the process of capturing the Philippines, more than $20.5 Million in U.S. and local cash and an unknown amount of foreign currency and bullion in that capital city and after that,the Japanese Military would confiscate all hard currency, both on a federal and individual level, and replace it with notes printed locally and bearing a proclamation of military issue. The Japanese used this hard currency abroad to purchase raw materials, rice and weapons to fuel and feed its war machine. In its place the Japanese issued several series of invasion notes.

All notes bear the name of the issuer, “The Japanese Government” while some notes proclaim the “promises to pay the bearer on demand…” This money, called “Mickey Mouse Money” by local Filipinos was considered valueless after the overthrow of the Japanese, and literally tons of it was burned. Additionally, Japanese troops were ordered to destroy bank records and any remaining currency prior to capitulation

The occupying Japanese government issued fiat currency in several denominations known as Japanese government-issued Philippine fiat peso. The Japanese-sponsored Second Philippine Republic under Jose P. Laurel outlawed possession of guerilla currency and declared a monopoly on the issuance of money and anyone found to possess guerilla notes could be arrested.
Due to the fiat nature of the currency, the Philippine economy felt the effects of hyperinflation.
Japanese troops go ashore to complete the occupation of Corregidor island. General Homma’s original plan of attack had nearly been defeated by strong American resistance—but his forces had gained a foothold despite their losses, and fought their way towards the heart of Wainwright’s defense at Malinta tunnel.

The Filipinos called the fiat peso, "Mickey Mouse" money, because it was similar to play money and next to worthless. 75 Mickey Mouse pesos, or about 35 U.S. dollars at that time, could buy one duck egg.In 1944, a box of matches cost more than 100 Mickey Mouse pesos.
Many survivors of the war tell stories of going to the market laden with suitcases or "bayong" (native bags made of woven coconut or buri leaf strips) overflowing with the Japanese-issued bills. This story is similar in all the occupied countries, the only difference is the thing used to carry the banknotes but these situations are all the same.

Additionally, Japanese troops were ordered to destroy bank records and any remaining currency prior to capitulation

The first issue in 1942 consisted of denominations of 1, 5, 10 and 50 centavos and 1, 5, and 10 Pesos. 1943 brought “replacement notes” of the 1, 5 and 10 Pesos while 1944 ushered in a 100 Peso note and soon after an inflationary 500 Pesos note.
Near the end of the war in 1945 the Japanese issued a 1,000 Pesos note. Plates for this note were first completed in Manila shortly before U.S. troops entered the city on 3 February, 1945, and the Japanese printed the 1,000 Pesos note while they were retreating from Manila to Baguio. The Japanese were on the defensive and short of supplies, including printer’s ink, which they diluted with duplicator fluid in an effort to stretch their stores. These invasion notes are shown below including an issue unknown to many collectors featuring Jose Rizal on it.

1942 Issue
1943 Issue

1944-1945 Issue

After Us Troops landed in the Philippines, many Filipinos were reluctant to accept the Japanese military notes introduced and prompted the Japanese to issue a new currency which they hope would be more acceptable by designing notes bearing the Jose Rizal and would be printed in Tagalog instead of English and issued in the name of “Bangko Sentral ng Philipinas” under the authority of “Republika ng Philipinas”.However there wasn’t enough time and by the time the first note was completed the war was over.Below is the only denomination that was finished and was never circulated in the public.

Japanese invasion money of Indochina

Flag of Indochina under Japanese Occupation

Indochina or present day Vietnam,Cambodia and Laos and was occupied before the invasion of Malaya.In August 1940, Japan pressured the French government to allow Japanese forces to be stationed in northern Indochina, adjacent to the border with China. A year later the Japanese would have 40,000 troops stationed there. By September 1941, Japanese forces were marching into Saigon.

There were two years in which these notes are issued.First issue was between 1938-1940 and the second issue was in the year 1942.These notes looks like the Military yen of the Japanese occupation of China and they both contain almost similar designs and currency unit.These are the issues of the invasion money and their respective date.

Japanese invasion money of Malaya

Japanese troops advancing through Kuala Lumpur
The Japanese had attacked Malaya on the same day as the attack on Pearl Harbour. The Japanese who were much better trained and equiped swiftly took Malaya in less than two months far shorter than what the British took to control Malayan states from its rulers many years before.General Yamashita became known as the Tiger of Malaya for his successful conquest of Malaya.Singapore then fell although it had much more men than the Japanese and the British army surrendered.Soon after that British North Borneo,Brunei and Sarawak fell, luckily for the White Rajah of Sarawak, he and his family had gone to Australia before the invasion and stayed there during the duration of the war.

Following the fall of Singapore on February 15,1942 the Japanese had designed banknotes for the use in Malaya,Brunei,British North Borneo and Singapore and introduced it as a replacement for the local cureency which at that time was the Malayan Dollar.These notes were to be exchanged at a rate of 1:1.The Japanese wanted everyone to exchange all Malayan Dollars for the Japanese Occupation banknotes and for those who did not comply with this rule would be severely punished by the authorities. Some people had hid some of their Malayan Dollars as they anticipated that it would be worth more when the British returned to become the rulers again.

To supply the authorities with money whenever they required it, they simply printed more notes. This resulted in high inflation and a severe depreciation in value of the banana note. Moreover, counterfeiting was rampant due to its lack of a serial number on many notes. Increasing inflation coupled with Allied disruption of Japan's economy forced the Japanese administration to issue banknotes of larger denominations and increase the amount of money in circulation. Sharp drops in the currency's value and increased price of goods frequently occurred following a Japanese defeat in battle abroad.

The Japanese had issued paper script currency of 1, 5, 10 and 50 cents and 1, 5 and 10 dollars in 1942. The 1, 5 and 10 dollar notes initially had serial numbers; these were later omitted. In 1944, inflation lead to the issuing of a 100 dollar note. In 1945, a replacement note 100 dollar bill was issued as well as a hyper-inflation 1,000 note. The 1942 series of notes, including the 50c and 1, 5, 10, and the 1944/45 100 dollar all contained the text [The Japanese Government] “Promise To Pay The Bearer On Demand”. Interestingly, the 1944 ,100 dollar replacement note no longer contained this message.No coins were issued during the occupation as the metals needed to produce was better used for the war effort, that is why the paper notes of 1,5,10 and 50 cents were issued instead of metal.Many people had stacks of these notes and going shopping was a troubling activity due to the fact that they had to carry bags of currency around

One must be wondering how is it like during the occupation with all this inflated money,well In Theresa Ee-Chooi's biography of her father Ee Peng Liang, she noted that an egg went for $100. During the Japanese Occupation, $100 buys you one egg. Lee Chin Gee, son of Lee Choon Seng, a former chairman of OCBC, told the bank's biographers that he sold his wife's gold chain for $3,500. Yet that money was not enough to buy even two big fishes, so he settled for a medium-size fish and two bananas. Many people at that time could be seen going shopping with a big bag of this worthless money.After the war ended many people who were suffered so much during the occupation simply burned the money, imagine if they knew how much one piece of this worthless money is worth they would think twice before doing so.
General Tomoyuki Yamashita,the Tiger of Malaya captured Malaya

The 1,5,10 cents had prefixes of fractional letters and block letters.The 1,5 and 10 dollars with serial numbers are worth much more than the ones with block letters and they are quite rare to,finding one is a blessing for a collector of these invasion banknotes.The second type of the 100 dollar note with an image of rubber tapping is worth much more than the one with the two buffaloes behind the note.The first letter M on all notes represent Malaya the area where this currency should be used. Block letters prefix worth more
Fractional letters prefix worth more
Block letters worth more

The second version of the 100 Dollar note(above),worth more than the common one (below)

If the prefix of the 1000 Dollar note is black instead of red, you just found yourself a small fortune
