Yet despite the existence of legitimate academic article databases, users from around the world download over 350,000 articles each day from Sci-Hub; almost 3,800 of those daily downloads originate in Japan. In this paper, we first outline the trends pertaining to Sci-Hub. Next, we analyze the Sci-Hub download log data from 2017 and investigate the Sci-Hub Usage in Japan. Comparison of the results with Kuriyama\u2019s (2016) survey reveals that the number of downloads and citations confirmed that Sci-Hub use has increased.
