They met on a total of about 10 occasions, with the former worker allegedly receiving meals and entertainment, as well as cash totalling some 700,000 yen, in exchange for the information.
The MPD believes the former worker became aware of the industrial espionage nature of the meetings over time, but failed to sever the relationship.
The two reportedly communicated exclusively in Japanese verbally during meetings, making subsequent arrangements on the spot.
They are believed to have avoided phone calls or emails, a common tactic used by Russian operatives to avoid leaving traces.
This marks the first case built by the MPD against alleged Russian espionage since 2020, when a former Russian diplomat in Japan was referred to prosecutors over confidential corporate information leaked by a former manager of Japanese mobile communications firm SoftBank Corp.
Japanese police have built 11 such cases in total since the former Soviet Union collapsed in 1991.
