That gives managers at Suntory, whose non-alcoholic brands include Ribena, Lucozade and Orangina, another incentive to come up with a design that works.
"We are working on how we can have izakaya gatherings using face shields," Niinami said in an interview. "It looks weird but being weird may be acceptable in the new normal."
The team at Suntory have generated several ideas, from face shields that resemble an astronaut's helmet to a sun visor hat that customers could keep on while eating and drinking. The hope for both is that they contain any virus-laden droplets while allowing people a proximity to each other previously standard in bars and pubs.
The company has not released any photographs of the proposed new designs.
Japan's hospitality sector has so far relied on a mix of social distancing measures, disinfectants, masks, temperature checks and plexiglass shields on tables to keep people safe.
Already punished by the lockdowns governments imposed across the world, the hospitality sector faces a fraught reopening given the risk that alcohol reduces discipline on social distancing and many pubs, bars and restaurants only have indoor space.
Experts in the UK will be watching to see whether infection rates have climbed since pubs were allowed to open earlier this month. In Texas, which is in the grip of a severe outbreak of Covid-19, governor Greg Abbott has said he reopened the state's bars too quickly.
Suntory, which competes against the likes of AB InBev and SABMiller, has already tested some prototypes on employees of izakaya pubs.
But company officials admit that they have yet to come up with a winning design, with some staff at the pubs where the prototypes were tested complaining they were cumbersome and awkward to wear. It is also unclear whether customers would be willing to reuse a shield that has been used by others even if they are washed and disinfected.
Although Niinami has recently rejected several ideas from his team because they fell short on reducing infection risk, he has not given up.
"It may not be a state of art technology but we have to think outside the box," said Niinami, pointing to the need to be creative in this crisis.
