The Background / Challenge
Hana-Musubi 華御結, a premier Japanese-inspired rice ball brand in Hong Kong, has partnered with Prizm for the past three years to enhance customer engagement and retention through a comprehensive CRM and Loyalty Program. The initial objective was to establish a robust membership base and incentivize repeat purchases with a structured rewards system.
As membership growth surged, Hana-Musubi recognized the need to elevate the customer experience further. To achieve this, they introduced fully automated ordering platforms, including:
- Point of Sale (POS) System
- Self-Service Kiosks
- Mobile Ordering App
These digital solutions were meticulously designed to integrate with Omusubi 's in-house developed omusubi vending machines, ensuring a seamless and efficient ordering process for customers.
Current Challenge:
In light of Hong Kong's economic slowdown, Hana-Musubi has faced a decline in sales growth. In this competitive landscape, the brand increasingly relies on its loyalty program to drive repeat purchases and sustain revenue.
Prizm's CRM and data-driven loyalty strategies play a pivotal role in assisting Hana-Musubi to:
- Increase customer retention through personalized rewards and promotions.
- Encourage higher purchase frequency via targeted engagement campaigns.
- Optimize marketing spend by leveraging customer insights from Prizm’s analytics.
By continuously refining the loyalty ecosystem, Prizm ensures that Hana-Musubi remains a preferred choice for Omusubi enthusiasts in Hong Kong, even amid challenging economic conditions.
The Strategy
To enhance customer loyalty and drive repeat purchases, we developed a dynamic loyalty program with the following key components:
- Personalized and Rewarding Offers
- Tailored Discounts & Bundles
- Tiered Rewards
- Gamification Elements
- Prepaid Membership
To improve cash flow and customer commitment, we introduced:- Prepaid Credit Packs
- Exclusive Member-Only Deals
Win-Win Outcome is expected:
-
- For Hana-Musubi: Stabilized revenue stream and improved liquidity.
- For Customers: Enhanced value and convenience.
- Discount Card Subscription
To cultivate long-term engagement, we launched a subscription-based discount card:- Monthly/Annual Plans: Subscribers pay a fixed fee (e.g., $50/month) for unlimited discounts (e.g., 10% off every purchase).
- VIP Perks: Subscribers gain early access to exclusive omusubi and events.
This approach helps predict revenue while fostering brand loyalty.
- Data-Driven Marketing
Utilizing customer lifecycle analytics, we implemented targeted marketing initiatives:- Segmented Campaigns: New customers receive exclusive offers, while loyal members get personalized discounts.
- Behavior-Based Triggers: Automated reminders and offers are sent based on customer behaviors (e.g., cart abandonment).
- Preference-Based Recommendations
- Streamlined Purchase Experience
To enhance convenience, we focused on simplifying the ordering process across all touchpoints, including:- Pre-order and Skip Queue Options: Minimizing wait times

The Execution
To successfully implement Hana-Musubi’s digital transformation and loyalty strategy, Prizm adopted a phased, data-driven approach based on four core principles:
- Start Small – Pilot Testing Under "Omusubi" Brand
We launched the new loyalty program and automated ordering systems under the "Omusubi" sub-brand to:- Minimize risk
- Gather early feedback
- Refine mechanics
Key Actions:
-
- Launched initial engagement drivers like Stamp Cards and Missions.
- Introduced self-service kiosks in select locations.
- Monitored adoption rates and customer feedback.
- Quick Test, Analyze, Enhance – Iterative Rollout
Features were deployed incrementally for continuous optimization:- Phase 1: Launched Stamp Card & Missions to drive trial and measured redemption rates.
- Phase 2: Introduced a Loyalty Points System, tracking member retention and average spend.
- Phase 3: Tested a Prepaid Wallet in high-traffic stores, monitoring cash flow impact.
- Data-Driven Decision Making
Every initiative was tracked and analyzed in real time:- Evaluated coupon efficiency, member growth, and customer lifetime value.
Actions Taken:
-
- Adjusted discount structures based on redemption patterns.
- Scaled successful campaigns (e.g., "Double Points Week").
- Paused underperforming features to reallocate resources.
- Hyper-Personalization
We implemented dynamic customer profiling for targeted marketing:- Behavioral Tagging
- Preference-Based Automation
- Lifecycle Marketing
- Scaling Success – Full Brand Rollout
After validating the model with Omusubi, we expanded the loyalty program to all physical stores, integrated mobile ordering and kiosks chain-wide, and launched subscription plans as a premium retention tool.
Key Takeaway: By starting small, iterating quickly, and using data to guide decisions, we ensured maximum ROI on every investment.
