Analysis of Restaurant Sales Trends in June 2026

Postas Inc., headquartered in Chuo, Tokyo, has recently published the sales trend report for restaurants based on POS data for June 2026. The findings indicate a slight decline in sales in comparison to the previous year, reflecting changing dynamics within the restaurant industry.

Sales Performance Overview

In June, the total sales compared to the previous year stood at 97.9%, marking a decrease of 5.8 percentage points from the previous month. This represents the first negative growth in 9 months, suggesting a significant shift in the market.

When analyzing sales across geographical regions, the average year-on-year growth rate for June was 99.4%, which also saw a reduction of 4.5 points from May. Unlike the prior month, which saw exceptional boosts due to the Golden Week, the sales remained level throughout June.

A deeper dive into the daily sales trends reveals that during dinner hours, izakayas (Japanese pubs) led in sales, followed by specialist cuisine restaurants. In contrast, during lunch hours, quick-service (light meal) restaurants topped the charts, indicating varied consumer preferences throughout the day.

Cashless Payment Trends

The report reflects an increase in cashless payment adoption, with the national average now at 57.3%, up by 0.7 points from May. This suggests a growing acceptance of digital payment methods across various dining formats, where all categories exceeded a 40% adoption rate. Notably, both meal-centric and take-out formats embraced code-based payment systems, surpassing a 10% usage rate.

However, differences in cashless payment adoption remain pronounced across genres. Out of 28 categorized dining segments, 22 exhibited cashless transaction ratios exceeding 50%. For instance, the highest cashless adoption was seen in teppanyaki restaurants at 75.5%, whereas ramen shops trailed at 35.4%, illustrating stark contrasts between genres.

Comparatively analyzing the data from May to June, it becomes evident that the cashless payment rates have notably increased in categories such as specialist cuisine and izakayas. Specifically, credit card usage among izakayas surged by 1.3 points, standing out as the most significant increase, while other payment methods remained consistent.

In terms of transaction preferences nationally, credit cards continue to dominate at 45.1%, followed closely by cash at 42.7%, maintaining a 2.4-point margin.

Reports Summary

In summary, June 2026 reflected a pivotal moment for the restaurant sector, with an overall sales index of 97.9%, showing a downward trend in comparison to previous months. Regional sales patterns displayed consistency with last year’s figures, while the method of transaction demonstrated a positive tilt towards cashless options.
