Jobs-to-be-Done

"When SoftBank needs to communicate complex technology investments and portfolio strategy to a global audience, make the digital experience as sophisticated and forward-looking as the company itself."

This is the core job SoftBank Japan hired Tebeau Group to get done — the real outcome they needed, not just the deliverable they asked for.

What We Built

Scope of Work

Comprehensive solutions delivered across strategy, design, development, and marketing.

Responsive Design System

Designed and built an award-winning responsive design system that delivered a consistent, premium experience for SoftBank's 50M+ monthly users across mobile, tablet, and desktop. The design system was built to accommodate the specific typographic and layout requirements of Japanese digital design — including high-density information presentation, kanji-optimized typography, and the visual hierarchy conventions that Japanese users expect from a tier-one telecom brand.

Responsive DesignDesign SystemMobile-First

Japanese Market UX

Developed UX design optimized for Japanese user behavior patterns, typography standards, and cultural design preferences — a discipline that requires deep understanding of how Japanese users navigate information-dense digital environments differently from Western users. The UX work included user research with Japanese consumers, information architecture adapted for Japanese content density norms, and interaction patterns that felt native to the Japanese digital experience.

Performance Optimization

Executed front-end performance optimization that achieved sub-2-second load times across all device types in the Japanese market — a critical benchmark for a telecom brand whose customers judge their network by the performance of their own digital properties. Optimization work included image compression, critical CSS extraction, lazy loading, and CDN configuration optimized for Japan's network infrastructure.
