Japan’s capital expenditure boom is shifting to the services sector, stirring fears that self-checkout systems and software will take the human touch out of omotenashi, the country’s vaunted commitment to hospitality.

The economic forces at work are undeniable. The working age population is forecast to shrink by about one-third in the next half century, and companies simply cannot hire enough workers.

Turning to automation raises productivity and removes a bottleneck to economic growth — but marks a retreat from a services-oriented culture where the customer is king.

“The level of omotenashi depends on where you shop, but regardless, we place a lot of emphasis on face-to-face interaction,” Naoki Kobayashi, 52, a sales manager at a telecommunications company, said after buying drinks from a store in northern Tokyo that had no staff. “We also have a shrinking population, so I can understand why some retailers have to change.”

East Japan Railway Co. worked with information technology consultancy Signpost Co. to set up the store last month at Akabane Station.

For payment, shoppers swipe a special card at the entrance and again when they leave. AI-powered cameras track which products they choose.

There are still some bugs: In Kobayashi’s case, the system confused his order with that of his co-worker. The staff-less store is still being tested but could be opened elsewhere in response to labor shortages, a JR East spokesman said.

Omotenashi helped Japan rank No. 1 last year in customer satisfaction, according to a World Economic Forum study on tourism.

Most commonly, it embodies intense personal interaction with customers, an extreme willingness to respond to even the slightest request, to speak only the most polite Japanese, and to bow frequently.

Even workers at supermarkets and budget hotels are trained to bow, speak in polite tones and are more attentive than most of their counterparts abroad.

But Japanese companies are now forced to consider how much of a personal touch they can afford. The ratio of new jobs to applicants is already at a four-decade high and is likely to rise even further.

Japan’s working age population will fall 35 percent to 50.7 million in 2065 from 78.1 million in 2015, the United Nations says.

Capital expenditure in the services sector, which started to accelerate in the last quarter of 2016, rose 9.2 percent in the first half of this year, the fastest increase in almost three years.

The investment could pay off in Japan, which has the lowest productivity among Group of Seven countries.

Matsuya Foods Holdings Co. is remodelling some of its beef bowl restaurants to self-service. Customers pick up their food from a counter, pour their own tea and clear their own trays, meaning less interaction with staff.

Convenience store operator Lawson Inc. is testing a system that allows shoppers to scan and pay for goods with their mobile phones.

At Takashimaya Co.’s Nihonbashi department store in central Tokyo, veteran concierge Masanori Shikita, 71, scowled when asked whether omotenashi will lose its human touch.

“Our basic philosophy is we put people first,” he said. “Omotenashi means you remain at the customer’s side, and you see things from the customer’s perspective as you show them hospitality.”

To be sure, some elements of the customer service tradition are not likely to disappear. Takashimaya’s building in Nihonbashi, constructed in 1933, is designated an important cultural property and has elaborate, staff-operated elevators.

Yuria Nagamoto, 22, has been working as an elevator operator for the past three years. Dressed in a dark uniform and pillbox hat, she announces what items are available before stopping the elevator at each floor.

“At Takashimaya, customers ask you so many different questions that I had to study a lot, but it is important to be able to reply to the customers’ needs,” she said.

But some companies say machines help them keep the human touch in omotenashi.

Fast Retailing Co. has installed self-checkout tills at 195 stores for its low-cost apparel brand GU. The company says customers like the machines, but it will not cut staff.

“The new system increases efficiency for store operations significantly, hence store staff can spend more time with customers when shopping,” a spokeswoman for Fast Retailing said.

“This initiative actually improves our service level.”
