Neodymium magnets
In August 2015, Nitto Denko announced their development of a new method of sintering neodymium magnet material. The method exploits an "organic/inorganic hybrid technology" to form a clay-like mixture that can be fashioned into various shapes for sintering.  Most importantly, it is said to be possible to control a non-uniform orientation of the magnetic field in the sintered material to locally concentrate the field to, e.g., improve the performance of electric motors. Mass production is planned for 2017.

Sponsorships
On 25 May 2017, it was announced that Nitto Denko will be the main sponsor for the ATP Finals, at least until 2020. On 10 September 2020, Nitto Denko announced it will extend its title partnership of the ATP Finals for another five years, until 2025.
