Gyutan Sumiyaki Rikyu Implements Workplace Management Tool 'hataLuck App' — Building an internal information-sharing environment to bring Miyagi's culinary culture nationwide —

HataLuck and Person Co., Ltd. announced that 'Gyutan Sumiyaki Rikyu,' operated by Rikyu Co., Ltd., has fully implemented the service-industry-focused store management tool, 'hataLuck app.' As Rikyu expanded its store footprint and diversified its workforce, it faced challenges with fragmented information sharing and a dilution of its corporate brand culture. By leveraging the 'hataLuck app' for last-mile communication, the company has seen improvements in sales capability and a stronger infiltration of its brand culture.

### About the 'hataLuck app'

The 'hataLuck app' is a dedicated business application specialized for the service industry. Designed to enhance productivity and engagement, it provides an all-in-one solution including shift management, communication, manuals, and surveys. It is accessible from the smartphones of store employees (part-timers and store managers) and has been adopted across various sectors including dining, hotels, retail, and entertainment since its 2019 launch.

### About Rikyu

Since its founding in 1988, Rikyu has delivered the charm of Miyagi's local produce nationwide through its self-manufactured 'Gyutan-yaki' (grilled beef tongue). Accelerating its national expansion, the company adopted the tool in 2025 to ensure employees embody the spirit of 'making customers smile' and to establish a timely information-sharing environment.

### Challenges Before Implementation

Previously, store communication relied on a mix of paper, emails, and various chat tools, leading to siloed information. As stores expanded, there was a growing challenge in ensuring headquarters-level information reached frontline staff, and a dilution in brand awareness concerning Miyagi's food culture.

### Results

1. **Unification of In-Store Communication** Consolidating shift submissions created a common communication platform for all staff. This streamlined shift planning and personnel management, while automated labor cost tracking enabled more precise alignment with budget requirements.

2. **Sales Enhancement Through Information Sharing** By utilizing the 'Contact Note' function to share sales data, stores achieved a 224% increase in sales of featured products and a 160% increase in purchase index (PI value) compared to stores that did not, fostering a sense of ownership among staff.

3. **Infiltration of Brand Culture and QSC Improvement** The company established a system to share customer feedback between headquarters and individual stores, driving company-wide improvements in QSC (Quality, Service, and Cleanliness). Internal newsletters and unique communications regarding food culture have helped create a fun, educational workplace environment.
