Naikai Zosen Corporation: what insiders have been doing
Headquartered in Onomichi, Japan, Naikai Zosen Corporation is a listed company and traces its origins to 1944. Its latest reported headcount is 611 employees (2023). Filings by its managers are published through EDINET (Japan FSA). In the past year (18 October 2025 to 18 October 2026), 4 filings came from 1 insider.
Not one of the filings records a straightforward purchase or sale on the market. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.
Insider buying of Naikai Zosen Corporation has been absent for the past year. Filings reach the EDINET (Japan FSA) feed a median of 7 days after the trade. The shorter that gap, the sooner other investors can see what insiders have done.
With 4 filings in twelve months, the company is more active than the median of 3 filings across the 3,419 companies we follow on the same exchange.
