Pushing back on the F1 engine in his second year
He was transferred to the engine development team of Honda's second F1 era. He confronted his superior over an engine with an extremely big bore, saying, "Of course it breaks," and was lectured almost every night at a yakitori shop in Narimasu.

Building a four-cylinder on his own in the six-cylinder department
Honda, then struggling financially, did not have the means to build a factory for a large minivan. To build it at an existing plant, the body had to be smaller, which meant it could only take a four-cylinder. Asaki, who was in the six-cylinder development unit, began developing a four-cylinder no one had asked for, and kept going even when he clashed with his boss. Some in the company mocked it as a "hot-spring car," but the first Odyssey was a big hit and saved Honda.

Fitted to
The hardest of all: cylinder deactivation
The V6 fitted to the fourth-generation Inspire rests the three cylinders on one bank while cruising to save fuel. Resting them causes vibration. Asaki turned to an active engine mount that had been built in-house for diesels but had never been used, and won over its developer, half by trickery, to work with him. He says the hardest thing he ever worked on was not the N-BOX or F1, but this cylinder deactivation.

Honda can't build it cheaply, so it has to be the roomiest
With the strong yen after the Lehman shock making exports difficult, Honda needed a car that would sell in Japan. In kei cars, where price decides everything, Honda could not build cheaply. So it set targets of the world's smallest engine compartment and the largest cargo space within kei car rules, bringing the minivan thinking that began with the Odyssey to a kei car. In his own words, a "mini-minivan." It was developed with a sense of crisis that Honda would be in trouble if it didn't sell.

Six months from retirement, called back to F1
After launching the N series, with six months to go before retirement, he was put in charge of developing Honda F1's power unit. He withdrew his retirement to take it on. For the MGU-H, which kept failing, he brought in engineers from Honda's own HondaJet program, who identified the problem with the bearing position.
The championship in the year of withdrawal
In Honda's final year before withdrawing from F1, Verstappen, with a Honda power unit, won the drivers' championship. When years without wins go on, engineers acquire a "losing habit" of looking for excuses. That, he said, was the one thing he did not want to leave behind.
