Otoriyose.net Transforms with Generative AI

In an ambitious bid to modernize user experience, Otoriyose.net, one of Japan's largest gourmet review platforms, has undergone a complete revamp using a generative AI-driven development technique known as Vibe Coding. Managed by Island Corporation based in Shibuya, Tokyo, this transformation was officially unveiled in May 2026, marking a significant leap forward for the long-established platform.

Key Achievements and Innovations

The redesign not only enhances aesthetic appeal but significantly boosts functionality. Within just one month of its launch, the platform has achieved notable results:

• - SEO Score: A perfect score of 100 on Google’s PageSpeed Insights for both mobile and desktop versions, showcasing outstanding performance and optimization.
• - Increased User Engagement: Individual page views per user have surged by approximately 25%. This improvement can be attributed to enhanced responsive design and optimized navigation, encouraging users to explore more products.

Addressing Longstanding Challenges

For over two decades, Otoriyose.net has served as a crucial bridge between gourmet food providers across Japan and consumers. Yet, this long history came with challenges. Originally built without consideration for mobile devices, the system had grown increasingly complex, leading to a decline in the site improvement pace and issues with URL fragmentation between desktop and mobile interfaces.

Recognizing these hurdles, the latest redesign was initiated to streamline user experience and enhance service adaptability moving forward.

Vibe Coding: A New Era in Development

The technical overhaul was spearheaded by Koji Hasegawa, the development lead who has been integral to the platform since its inception in 2003. By implementing Vibe Coding, Hasegawa enabled engineers to engage in a symbiotic relationship with AI, merging human creativity and machine efficiency.

Here’s a timeline of the transformation:

• - November 2025: Idea conception began with design implementation tests using ChatGPT. This stage validated the feasibility of AI integration in the redesign.
• - December 2025: Commencement of the full-scale overhaul while addressing early-stage challenges related to AI memory and prompt optimization.
• - January 2026: Transitioning to Google Antigravity allowed for direct AI modifications to the source code, enhancing development speed to three to five times faster than prior methods. This facilitated simultaneous development across three different system aspects.
• - February to April 2026: Collaborative design efforts used Figma to create layout prototypes, which AI subsequently coded. This phase emphasized confirming design accuracy and optimizing user interface efficiency through meticulous testing methods.
• - End of May 2026: The platform was launched fully responsive, equipped with an AI concierge feature to assist users in finding their ideal gourmet products.

A Commitment to User Experience

Hasegawa expressed pride in creating a site where users can effortlessly discover delectable offerings. The revitalized platform not only disentangles the complex site structure but also supports rapid service improvements in the future, ensuring that Otoriyose.net remains a valuable resource for food enthusiasts across Japan.

The redesign also showcases Otoriyose.net’s commitment to blending user-centric design with advanced technology. Features include an AI concierge to help users find the best products and a uniform interface responsive across all devices, solving the structural issues that have long plagued the site.

Looking Ahead

As Otoriyose.net embarks on this new chapter, it aims to continually bridge the gap between users and gourmet products by leveraging generative AI to enhance service speed and user satisfaction. This redesign marks not a conclusion, but a start towards creating enriched online dining experiences.
