Dokuyama has engaged with various controversial aspects of Japan's history, including nuclear displacement, 'comfort' women, and Japan's colonization of Taiwan. Having been deeply affected by the Fukushima disaster's impact on his hometown, the artist emphasizes the unpredictability of the contemporary world, exploring what it means to belong to a society in which people are too busy working to pay attention to the realities of politics and history. He often produces artworks based on interviews conducted while visiting locales where controversial incidents and events have occurred and been mediatized, investigating firsthand memories of these incidents as a way to reveal new truths, emotions, and histories that have been obscured by the pressures of meainstream society. Throughout his body of work, Dokuyama has attempted to maintain a neutral gaze from behind the camera, encouraging the personal testimonies and thoughts of participating interviewees and witnesses to waver audience perceptions regarding particular socio-political issues.
