Daihatsu CEO right now is ex Toyota regional CTO for APAC, so there's that. One of contributing factors, as being told in news narratives, is Daihatsu relied on shortened time to market and therefore reduced engineering man-hours as a cost saving measure, and there were barely enough time for scheduled tests, let alone for delaying ones affected by known issues, which had incentivized test engineers to just rig the test and/or forge documents. Toyota is also known for persistently demanding suppliers to contribute towards $20-30MM yearly cost saving target by reducing price by 1% every half years(~100MM and 5.85% every 3 years). That surely had contributed, and frankly that itself is a culture issue.
