After Taiwan became a Japanese colony in 1895 the government of Japan, always interested in proposals to increase its economic independence, began exploring the possibility of growing tropical drug plants on Taiwan.
The leader in such experiments was Hoshi pharmaceuticals, founded in the second decade of the 20th century. In the 1920s and 1930s, Hoshi was a leader in cinchona cultivation in Taiwan, and of cocaine, then used as an anesthetic.

Hoshi’s cocaine production grew quite large, and after better anesthetics were invented in the 1920s, Japan’s problem became disposing of all its production. Taiwan’s production was particularly useful. The coca leaf produced in Chiayi had twice the alkaloids of the Peruvian varieties (South America’s modern dominance of the cocaine trade is largely a historical accident of German chemistry, the US victory in World War II and Japanese destruction of Dutch coca plantations in Java during its brief occupation there) and it was far cheaper to ship it to Asian destinations than Peru.
How humans stimulate themselves is a product of politics and culture. In Taiwan, alcohol and betel nut, so destructive, are completely legal, while marijuana remains forbidden. Imagine today going down to Chiayi in some alternate universe to tour the endless plantations of high-quality coca or marijuana rather than betel nut trees and tea.
MALARIA

Cinchona became another key tropical product explored by Hoshi. The tree’s bark had long been recognized in Europe as a medicine against malaria, a problem until modern pesticide campaigns and swamp drainage wiped it out in most developed countries.
Westerners often associate malaria with the modern tropics, but in the US especially before the 1880s it was deadly, accounting for roughly 4.5 percent of all child deaths, and a major drag on the economy, just as it is today in malarial regions. Even in the brutal Little Ice Age in the 17th century, malaria was common in London and the surrounding region. Shakespeare refers to it in eight of his plays.
With Japan colonizing Korea, Taiwan and Manchuria, with plans to expand further south, malaria treatments became an urgent security issue. Into the 20th century it was the number three killer in Taiwan, after cholera and plague, and as late as 1940 it sent 1.7 million people to local hospitals and clinics. It wreaked havoc on Japanese soldiers in Korea, and a milder strain plagued Chinese mine workers in Manchuria, reducing coal output.

CINCHONA PRODUCTION
During Japan’s 1874 invasion of southern Taiwan, the army’s medical teams reported nearly 8,000 cases of infectious disease, roughly 4,500 of which were malaria. Cinchona had been introduced into Japan in 1876, but cultivation failed, and an attempt to grow it in Bonin Islands foundered. Given the empire’s problems with malaria, growing cinchona in Taiwan looked like a no-brainer.
As scholars have noted, Hoshi saw the western monopoly on cinchona as a threat to Japan. Japanese thinkers also proposed cultivation of cinchona as a way to solve what the Japanese saw as “the aborigine problem” — the problem of imposing Japanese imperial power on aborigines defending their lands.

Japanese scientists argued that Taiwan’s indigenous population needed to be moved away from slash and burn techniques, and that cultivating cinchona would create a more “sustainable” way of life. Of course, they also argued that since the indigenous population had no concept of land ownership, they didn’t own the mountain lands.
According to scholars Heather Rogers and Kelly Chan (“Mapping Ecological Imperialism: A Digital Environmental Humanities Approach to Japan’s Colonization of Taiwan,” Material Culture Review, Fall, 2022), Japanese thinkers saw this as a humanitarian and cooperative approach under which indigenous communities would be integrated into the colonial economy through cinchona cultivation on plantations and receive food and low-level agricultural educations.
“This dynamic thus placed agriculture at the center of the structure of colonial relations,” Rogers and Chan observe. In the form of indentured servitude for indigenous communities, I might add.
Successful cultivation of cinchona began in 1922. Hoshi established plantations in Taitung and in Kaohsiung, with other companies and private individuals creating them elsewhere in Taiwan. All located on what had been indigenous lands, they ran on indigenous labor. By 1934 Hoshi had produced quinine from the bark, thus creating an integrated supply entirely within the confines of the empire.
In 1937 Japan invaded China, and demand for quinine became urgent. The government directed Japanese in Taiwan to plant 8,000 acres of cinchona, for a production goal of 2,400 tons of bark (one-fourth the production of Dutch Java). Though there are few surviving records, scholar Ku Ya-wen (顧雅文) has produced some tentative maps of their locations, all largely at altitudes of over 1,000 meters. Ku observes that wartime demand meant that Taiwan, once more or less self-sufficient in quinine, developed shortages.
One of the features of science-based medicines is that they are quickly uptaken into traditional and alternative systems and extolled for their assumed amazing properties. In Japan cinchona bark became a treatment for all sorts of ailments, from “hysteria” to impotence (impotence is apparently the most traditional of ailments), and enjoyed a kind of vogue in the 1930s.
WORLD WAR II AND BEYOND
After Germany ignited the second world war in Europe it became almost impossible for Japan to get hold of anti-malarials like quinine, atabrine and plasmoquinine from Germany. The occupation of Java with its immense plantations of cinchona, responsible for roughly 90 percent of world bark production, eased the situation briefly, but shipments to Japan fell off as the war progressed.
Quinine remained the most important anti-malarial until other drugs took its place in the 1940s, and colonial production of cinchona was less important. In his book How to Hide an Empire, Daniel Immerwhar observes that the development of new technologies such as plastics and artificial rubber made colonies obsolete. No longer did they produce unique raw materials.
Taiwan’s next colonizing power, the Chinese Nationalist Party (KMT), as George Kerr observed in Formosa Betrayed, seized the Japanese stocks of raw opium and coca leaves.
“The narcotics industry as a State concern had been always a source of great friction between Formosans and the Japanese administration,” he wrote.
According to Ker, in the mid-1930s the Japanese, even under figures doctored to avoid attracting attention, admitted to holding over 4,000 tons of coca leaves and 125 metric tons of cocaine.
A decade later Chen Yi (陳儀), whom Chiang Kai-shek (蔣介石) had appointed to run Taiwan, said that the government had recovered only 9,700 pounds of opium and “a small amount” of cocaine. Chen Yi also stated that production of cocaine and coca would cease, and that he was taking over the coca plantations.
According to Kerr, the US government reported in 1949 that it had received no information from the KMT government on the production or inventories of such narcotics in Taiwan.

May 11 to May 17 Traversing the southern slopes of the Yushan Range in 1931, Japanese naturalist Tadao Kano knew he was approaching the last swath of Taiwan still beyond colonial control. The “vast, unknown territory,” protected by the “fierce” Bunun headman Dahu Ali, was “filled with an utterly endless jungle that choked the mountains and valleys,” Kano wrote. He noted how the group had “refused to submit to the measures of our authorities and entrenched themselves deep in these mountains … living a free existence spent chasing deer in the morning and seeking serow in the evening,” even describing them as
Yesterday, the Democratic Progressive Party (DPP) nominated legislator Puma Shen (沈伯洋) as their Taipei mayoral candidate, the Chinese Nationalist Party (KMT) put their stamp of approval on Wei Ping-cheng (魏平政) as their candidate for Changhua County commissioner and former legislator Tsai Pi-ru (蔡壁如) of the Taiwan People’s Party (TPP) has begun the process to also run in Changhua, though she has not yet been formally nominated. All three news items are bizarre. The DPP has struggled with settling on a Taipei nominee. The only candidate who declared interest was Enoch Wu (吳怡農), but the party seemed determined to nominate anyone
In a sudden move last week, opposition lawmakers of the Chinese Nationalist Party (KMT) and Taiwan People’s Party (TPP) passed a NT$780 billion special defense budget as a preemptive measure to stop either Chinese leader Xi Jinping (習近平) or US President Donald Trump from blocking US arms sales to Taiwan at their summit in Beijing, said KMT heavyweight Jaw Shaw-kong (趙少康), speaking to the Taipei Foreign Correspondents Club on Wednesday night in Taipei. The 76-year-old Jaw, a political talk show host who ran as the KMT’s vice presidential candidate in 2024, says that he personally brokered the deal to resolve
What government project has expropriated the most land in Taiwan? According to local media reports, it is the Taoyuan Aerotropolis, eating 2,500 hectares of land in its first phase, with more to come. Forty thousand people are expected to be displaced by the project. Naturally that enormous land grab is generating powerful pushback. Last week Chen Chien-ho (陳健和), a local resident of Jhuwei Borough (竹圍) in Taoyuan City’s Dayuan District (大園) filed a petition for constitutional review of the project after losing his case at the Taipei Administrative Court. The Administrative Court found in favor of nine other local landowners, but
