■ Background of Implementation
At Kyo Unawa Main Store Jingu-michi, the low number of reviews on Google Maps was an issue. Around the time of opening, it remained at about 10 per month, a situation where the store's dedication and the appeal of its products were not fully conveyed.
Furthermore, verbally asking customers to post reviews had issues such as:
- High burden on the staff
- Tendency to feel pushy
Because of this, there was a demand for a mechanism that generates reviews naturally.
■ Overview of Measures
The store introduced an 'Eel Quiz', quiz-style content created using the no-code tool 'Croissant'. Designed to be accessible from a 2D barcode on tabletop POPs, they structured the following experiential pathway:
- Customers participate in the quiz during their wait time after arriving and being seated.
- They understand the store's dedication (ingredients, cooking) in a quiz format.
- After the quiz, they are guided to post a review in a natural flow.
The main points are as follows:
- Turned 'dedication', which is hard to convey in customer service talk, into a quiz, transmitting it without feeling pushy.
- Integrated the pathway for reviews into the content, making verbal requests unnecessary.
- Accommodated inbound tourists by including English notations.
■ Numerical Results
After implementing the measure, the number of reviews increased significantly.
Monthly reviews: From approx. 10 → Over 350
It was not merely an increase in volume; reviews containing specific details, such as 'The aroma of the Binchotan charcoal is good' or 'The female eel is tender,' also increased. This has led to improved appeal in search results.
■ Unexpected Effects
The quiz content itself functioned as a brand experience within the store. Cases where customers discussed the content after their visit increased, spreading into real-world word-of-mouth.
Also, eliminating the need for staff to verbally request reviews created an environment where they could focus on customer service, contributing to improved service quality.
■ Future Outlook
Moving forward, the store plans to update the quiz content regularly. By adding content tailored to seasons and themes, they will enhance an experience design that even repeat customers can enjoy.
■ Summary
Kyo Unawa Main Store Jingu-michi's initiative is an excellent example of turning waiting time into a valuable experience.
- Experience design utilizing wait times
- In-house management of the review pathway
- A customer attraction structure independent of advertising costs
'Croissant' can be utilized not only in restaurants but in 'various business types where customer wait times occur' as a tool that realizes such experience designs without coding.
