Jaitley, who arrived here yesterday on a six-day trip to Japan to meet investors and policymakers, is scheduled to meet Suzuki Motor Chairman Osamu Suzuki tomorrow.
"I think the Indian auto sector is extremely comfortably placed. This is all transient phase which happens and I don't think that with the kind of large market that Suzuki has, it is in any way likely to be adversely affected," he said.
The ban on sale of large diesel cars and sport utility vehicles with engines of two litres or more was first imposed in December and was recently extended to Kerala. The one in Kerala, however, has been temporarily stayed by the state high court.
It has led to some automakers reworking their plans and introducing models with petrol options or smaller diesel engines.

Maruti Suzuki India Chairman R C Bhargava had last month termed the ban as "totally arbitrary".
Maruti Suzuki, the country's leading automaker, has about 60 per cent of market share for petrol vehicles while for the diesel segment, the share stands at 28 per cent.
Earlier this month, the world's largest automaker Toyota said the restrictions would be the "worst advertisement of India".
