Timeline
Sep 2023 - Ongoing
JapanDen is designed to be more than just a hotel search engine. It's evolving into a content-rich gateway for travelers heading to Japan offering not just rooms, but real insights, cultural context, and connected experiences.
The challenge
The platform was set to launch together with the Tokyo 2020 Olympics, but due to the global situation got derailed. We had to bring it up to spec for launch in 2025, in a world that had changed, both in technology and expectations. This included a new search engine, rework of legacy code and updated property database, payment SDK and live re-sync with partner API.
What we found:
- Incomplete booking flow with a complex API connection
- Inventory management without live synchronization
- Outdated payment gateway to bring to the latest working version, including security, reliability and user demands
- Backend panel that was needing content management.
- Missing hotel and room images
- Old versions of Ruby, Rails, JS libraries, and out-of-date dependencies
Partnership
Goal
From day one, we aligned with the clients' team and stakeholders. JapanDen needed to be more than a site that could process bookings. It had to be stable, flexible, and scalable - ready to support new products, partner integrations, multi channel content, and a marketing strategy that matched the ambition behind it.
Our shared goal was to
Launch a stable MVP before peak travel season
Lay the foundation for a multi-product travel platform
Improve usability and performance across devices
Give full control of the CMS to the content team
Build confidence - for users, staff, and future partners
The Result:
Before & After
Before We Got Involved
- Booking logic was not matching with latest integration and documentation
- The partner API lacked important functionality
- Lack of automated processes, both for the user and admin staff
- Outdated Ruby gems, Rails and JS libraries in need of an upgrade, multiple flows in need of general refactor
- Content updates required developer support
- Search results were unreliable and caused frequent timeouts
After Our Work
3,000+
Hotelsupdated with images, descriptions, and room data
Dynamic searchSearch now uses dynamic ranking and filters out error-prone results
