TOKYO (AP) — Hiroo Onoda, the last Japanese imperial soldier to emerge from hiding in a jungle in the Philippines and surrender, 29 years after the end of World War II, has died. He was 91.

Originally, 引き揚げ (hi-ki a-ge, recovery) refers to the repatriation of Japanese civilians and non-combatant Japanese soldiers (with the ranks of 軍属 and 軍夫) after WW2 from occupied territories including China, Korea, Russia (also 樺太島, the Sakhalin Island, or 庫頁島 in Chinese), Southeast Asia, and of course, Taiwan. For the combatants (軍人), it was 復員 (fuku-in, to re-group); and for the IJN, 解員 (kai-in, to disband). More recently, however, 引揚 is taken to mean the repatriation of all Japanese.

Organized Japanese emigration actually started during the Meiji Era when the increase in population could no longer be supported by the agriculture. Some emigrated overseas to Hawaii and the Americas. The dominating military decided, however, that the most expedient way to resolving this issue was to grab lands off the neighboring Korea and China and send the Japanese there. And as they say: the rest is history.
The first Japanese immigrants of 133 families (385 members) arrived in Taiwan in 1899, organized by a private 賀田Kata company. They settled in Hua-lien area in a brand new village named 賀田村 (the village is still there today under the same name). This first attempt did not fare too well, though. The immigrants were allowed contractually to grow only sugarcane, not staple food. Plus eastern Taiwan was not exactly a hospitable place. There were the hostile Aborigines and malaria to contend with. Some died from diseases and many moved out or went back to Japan.
The pace quickened somewhat in 1909-18 after the Governor General of Taiwan had instituted a new policy that offered free land use plus 3 years of free medicine. Home construction, health care, and purchase of agricultural equipment were all subsidized. More than 1,700 immigrated and settled in Hua-lien and Tai-tung areas. Between 1917-24, private enterprises then took over and recruited more immigrants from 四國Shi-koku and 九州Kyu-shu. They were again all sugarcane farmers.
By 1932, the settlement sites had shifted to western Taiwan in the dry river beds in the southern plains of Taichung, Tainan, and Kaohsiung. In addition to sugarcane, the farmers were now permitted to grow rice and other crops to become self-sufficient. The tillable lands were divided into large squares and each village was completed with irrigation canals, levees, roads, and drinking water supply. About 4 hectares of land was allotted to each family; however, no land ownership was ever granted.
The immigrants were in fact all tenant farmers working for the Japanese-owned 製糖會社sugar factories. Their villages numbered:
Hua-lien and Taitung: 15
Taichung: 8
Tainan: 2
Kaohsiung: 3
And the total population of these farmers was around 50,000.
This farmer immigration into Taiwan was hardly a success; although the Japanese Government has thus far remained reticent on this issue. The farmers were only a small portion of the approximately 1/2 million (to be exact: 479,544) Japanese repatriated form Taiwan in 1946. Most Japanese immigrants at that time were not farmers. Instead, they occupied a higher niche, not only as the ruling class, but in a modernizing society, they were also administrators, businessmen, teachers, physicians, engineers, artists, musicians, students, military, and (the much feared) policemen. Most migrated to Taiwan on free will and stayed in metropolitan areas and small population centers (e.g., Danshui). And undeniably, gratuitous superiority complex sometimes did raise its ugly head.

Around 30,000 were allowed or asked to stay until 1948/9, most of them technicians and engineers needed for the infrastructure. And a few were scholars and university professors. An estimated 10,000 went underground, through marriages to Taiwanese husbands (some at the last minute) - never to re-surface as Japanese again. We remember one of these women living in Danshui as a shopkeeper who spoke Japanese-Hoklo to the great puzzlement of little kids.
And one of the few professors was 高坂知武Takasaka Tomotake (1901-1997) of National Taiwan University. He arrived in Taiwan an assistant professor in 1930, retired as Professor Emeritus and returned to Japan in 1987. He was a noted agricultural engineer/educator and an accomplished musician. He also founded the Imperial Taihoku University Symphony Orchestra which is now the NTU Symphony Orchestra. A building on NTU campus, the 知武館, was dedicated in 1989 in his honor.
A brief slide show of his life is presented here (accompanied by Haydn's Symphony No 94 in G-major - the very first piece performed by Prof Takasaka's orchestra in 1932):
