20% Sales Increase in 3 Months: Izakaya Chain Case Study

20% Sales Increase

"Maybe we've reached our limit."

The division manager of Company A, which operates a 25-store izakaya chain in the Tokyo metro area, murmured this in his late-night office.

Labor costs kept rising. But part-timers weren't coming. Food waste wouldn't decrease. Reservation calls rang non-stop during business hours. Store managers were exhausted, and turnover hit an all-time high.

"If we keep going like this, no one will be happy."

Thinking this, the division manager made a decision.

"The Phones Stopped"

The first thing they implemented was the LINE reservation system.

24 hours a day, AI handles customer reservations. "Friday at 7pm, party of 4." "Private room please." "I have allergies."—AI handles it all and confirms reservations.

One month after implementation, reservation calls dropped by 75%. Store managers were amazed: "I had no idea not having the phone ring could be this relaxing."

A Future We Can "See"

Next came the customer traffic prediction AI.

Historical data, day of week, weather, nearby events—combining all these, AI predicts "tomorrow looks like it will be a busy day."

Store managers just need to create shifts based on these predictions. They were freed from the dilemma of "schedule extra people just in case, and waste labor costs on slow days."

Less "Throwing Away"

Then came the AI ordering system.

Based on sales forecasts, AI suggests "order less fresh fish this week, more chicken." Store managers just confirm and click OK.

Food waste dropped by 30%. Kitchen staff who said "it hurt every time I had to throw things away" showed expressions of relief.

What Happened After 3 Months

Sales increased by 20%. Labor cost ratio improved by 4 points. Reservation completion rate rose by 24 points.

But what made the division manager happiest was something else.

"The store managers' faces brightened up."

When there's breathing room, people can smile. AI was the tool that created that breathing room.
