The Taiwanese community in Japan tends to be treated separately from the Chinese ( PRC ) community , both officially and socially , and is quite close to the local Japanese population . However , controversies have arisen due to dual-citizenship of ethnic-Taiwanese politicians in Japan , e.g. Renhō , since Japan does n't technically recognise the Republic of China on Taiwan as a legitimate country , and since Japan does n't allow dual-citizenship , especially not in politics . Japanese people tend to have positive views towards Taiwanese people due to shared history , shared culture , shared values , and the close ties between Taiwan and Japan . Following the 2011 Tōhoku earthquake and tsunami in Japan , Taiwan was the most prominent humanitarian contributor , donating US$ 252 million in combined aid under then-ROC-president Ma Ying-jeou 's administration . This is one major reason why Japanese people tend to have favourable views of Taiwan
