もっといいクルマをつくろうよ Motto ii kuruma o tsukurō yo. Let's make ever-better cars.
Akio Toyoda · 豊田章男 Toyota Motor Corporation chairman; president when the quoted 2019 comment was made
Toyota Times' official retrospective reproduces Toyoda's June 2019 post-Nürburgring comment. He recalls the frustration of racing without corporate backing and says that frustration became his steady axis as president; this is the phrase he kept saying.
Why this date: A Tuesday reflection on continuous product improvement.
Language note: もっといい (motto ii) means better or even better; つくろう (tsukurō) is the volitional 'let's make'. よ (yo) adds direct emphasis.
Continuous improvement becomes concrete when a team can say what 'better' means today.
DJW practice example: 昨日より、もっといいものを作ろう。 Kinō yori, motto ii mono o tsukurō. Let's make something better than yesterday.
