Web creation record

We were commissioned by Tokyo Gas Yokohama Chuo Energy Co., Ltd. to redesign their website.

The key points of this renewal were:

  • A large-scale website with over 1,000 pages
  • Structuring three sites for different purposes: corporate, recruitment, and renovation
  • Achieving both design quality and ease of updating

This project was built based on our KOTETSU BA Plan.
KOTETSU BA features a CMS structure that allows for easy updates. However, due to the extremely large volume of content for Tokyo Gas Yokohama Chuo Energy, the standard design components alone were not sufficient to fully express the content.

Therefore, we created additional custom design components as needed and handled the project flexibly.

In addition, for the top pages of the corporate, recruitment, and renovation sites, we applied our custom design option.
All of these top pages and additional components can be updated through the KOTETSU BA CMS interface.

Furthermore, Tokyo Gas Yokohama Chuo Energy had already been operating an owned media platform with several hundred pages of articles.
Migrating this data was also a key part of the project.

While addressing challenges such as the large data volume and differences in existing structures, we successfully completed the full data migration.

The client representative had a very high level of web literacy, which allowed the project to proceed smoothly overall.

However, due to the sheer scale of the project, it required a long-term and focused effort.
It ultimately became a highly rewarding project with a strong sense of accomplishment.
