The head of a Japanese university has been found guilty of research misconduct for self-plagiarism – technically, duplication – and has agreed to pay a one-time cash penalty for his transgressions.
According to the University of Aizu, a computer science and engineering school in Aizuwakamatsu, Toshiaki Miyazaki, the president and CEO, failed to appropriately cite his own work in four papers:

A tourism researcher in Japan has been suspended and demoted after university officials found that they had committed plagiarism in at least three papers in school publications.
In an August 4 statement, Atomi Gakuen Women’s University said Masami Murakami, formerly an associate professor, had been suspended from July 15 to September 14, and would now hold the rank of “full-time lecturer” at the school.
According to the statement, signed by university president Kiyoshi Kasahara, the punishment was “Based on the recognition of specific fraudulent activity (plagiarism) in the written paper.”

Ten months after a misconduct investigation into the work of a researcher in Japan four of his papers found to have serious issues have yet to be retracted.
According to an August 2020 report from National University Corporation Osaka University and National Cerebral and Cardiovascular Center Hospital about its investigation of Takashi Nojiri:

The misconduct case of an endodontics researcher in Japan who already has lost at least 24 papers for data problems has claimed two more casualties: the PhD theses of a pair of scientists he once helped train.
As we reported last year, Nobuaki Ozeki, who retired from Aichi Gakuin University in 2018, was found to have misused images, fabricated data and recycled text in 22 papers, 21 of which by our count have now been retracted. Ozeki’s total retraction count is 24, as three papers not identified in the investigation have also been retracted.
Now, we’ve learned that the university has revoked the doctoral degrees of two of Ozeki’s co-authors, Hideyuki Yamaguchi and Rie (Satoe) Kawai. Both researchers received their degrees in March 2016.

A scientist in Japan has lost her doctoral degree from Kyoto University after an investigation determined that she had plagiarized in her thesis.
According to the university, Jin Jing, who received her degree in September 2012 in human and environmental studies, has become the first person at the institution to have a doctorate revoked. In a statement about the move, Kyoto University president Nagahiro Minato said:

Nanotechnology researchers in Japan, who in November retracted a paper in Nature for lack of reproducibility, have retracted two more articles after what they said was a failure to replicate their findings.
As we reported previously, the authors, led by Kenichiro Itami of Nagoya University, called for an investigation into the problems with their work, the conclusions of which have yet to be made public.
The new retractions involve articles published in ACS Applied Nano Materials.
Here’s the notice for “Graphene Nanoribbon Dielectric Passivation Layers for Graphene Electronics,” a paper which appeared in July 2019 and has been cited 11 times, according to Clarivate Analytics’ Web of Science:

A materials scientist in Japan was found guilty of plagiarism and fabrication of data in a May 2019 paper, resulting in a six-month suspension, according to her institution.
Ye Zhang, of the Bioinspired Soft Matter Unit at the Okinawa Institute of Science and Technology Graduate University (OIST), was the senior author of “Enzyme-mediated dual-targeted-assembly realizes a synergistic anticancer effect,” which appeared in Chemical Communications on May 9, 2019. The paper has been cited seven times, according to Clarivate Analytics’ Web of Science.
According to OIST’s report on the case, five days after publication of the paper, a post-doc at the university filed a complaint with the school’s hotline, alleging that the article contained fabrication and plagiarism.
A month later, Zhang submitted a revised version of the paper to the journal, which issued the following correction:

A group of authors at Nagoya University and Kyoto University have retracted a 2019 Nature paper because of errors.
Here’s the retraction notice:

A stem cell researcher in Japan could end up with 23 retractions after officials at his former institution confirmed that he’d committed research misconduct in nearly two dozen papers.
According to a report released last week by Aichi Gakuin University, Nobuaki Ozeki misused images, fabricated data and recycled text in 20 papers. Ozeki has had 19 papers retracted to date, 17 of which are described in the analysis. The latest report — an offshoot of one in 2018 that found he had committed misconduct in three papers — expands Ozeki’s liability to 22 articles.
Ozeki has roughly 40 indexed journal articles on his CV, however, and journals may decide to conduct their own investigations into his work. Articles in the International Journal of Medical Sciences, Differentiation, and the Journal of Endodontics were named in the report but so far remain intact.

A group of researchers at Aichi Gakuin University in Nagoya, Japan, continues to lose papers for duplication of images and text from their previous work, and is now up to 19 retractions.
Please see an update on this post.
Here’s a typical notice, for “Bone morphogenetic protein-induced cell differentiation involves Atg7 and Wnt16 sequentially in human stem cell-derived osteoblastic cells,” a paper published in 2016 in Experimental Cell Research, an Elsevier title:
