mare interno, a Japanese data-tracking agency and Stape’s official partner in Japan, was approached by a client facing a challenge. A cosmetics manufacturer, running their e-commerce site on EC-CUBE — a popular local CMS — noticed that the purchase data in EC-CUBE didn’t match what appeared in GA4. The marketing team needed a solution for more accurate tracking. 

That's where mare interno stepped in, using Stape’s solutions to help the client optimize their tracking setup and ensure data accuracy.

Challenge: rebuild accurate tracking

Data discrepancies between EC-CUBE and GA4 limited accurate marketing insights. The company lacked an in-house system manager, so every fix required external help. They needed a simple, reliable way to make tracking accurate again.

Solution: switching to Stape server-side tracking

mare interno provided a solution that included:

The setup only took one day. Verification took longer since the site used EC-CUBE and an external CDN, but with Stape’s support, they got it working smoothly.

Results: recovered 76% of all previously blocked browser requests

After implementation, the team checked their Stape Analytics dashboard, and the difference was clear.

“In the first 30 days, Stape recovered over 360,000 events that were previously blocked by browsers. That’s about 76% of all requests. 
Since most of our client’s users browse on Safari, this made a huge difference in how complete and accurate our data became.
Cookie Keeper also reached a 99.99% success rate, which gave us a stable base for all tracking.”
— Kenichi Uchiumi, CEO at mare interno

Now, their client’s GA4 data accurately reflects what happens in their EC-CUBE store. 

Why it matters: the ready-to-use model for local EC-CUBE integration

mare interno is the first official Stape partner in Japan. They also created localized setup know-how for EC-CUBE, helping other Japanese brands improve tracking accuracy without hiring technical specialists.

After seeing strong results, mare interno plans to expand Stape’s server-side tracking to other platforms, including Shopify Japan.

Takeaway: reliable data and no maintenance through server-side tracking

The client’s client-side setup was losing conversions and valuable event data because of browser restrictions and ad blockers.

By implementing a managed server-side GTM via Stape, mare interno ensured that all tags and identifiers ran reliably on their client’s EC-CUBE store.

Using Stape Analytics, they validated full data recovery and performance stability.

Why choose Stape:

  • Quick, guided setup: no developers required.
  • Custom Loader and Cookie Keeper ensure accurate tag execution.
  • Stape Analytics provides transparency and proof of recovery.
  • Stable data across all browsers improves attribution, optimization, and ROI.
