One-Soup One-Dish: A Japanese Cooking Principle for AI Fatigue

Developer and creator Takuya, writing on his blog Devas Life, draws a parallel between the Japanese cooking principle Ichiju Issai (one soup, one dish) and the overwhelming pace of AI tooling. The core idea: strip away the unnecessary to maintain mental health and creative focus.

The Problem: AI Fatigue

New AI services emerge daily, and major releases from big companies change workflows weekly. Chasing every hype doesn't increase security — it clouds the essential skills developers need. Takuya calls this AI fatigue.

The Solution: Ichiju Issai for Tech

Ichiju Issai is a meal style centered around rice, one soup, and one side dish. Chef Yoshiharu Doi proposed it to free home cooks from the pressure of creating elaborate meals. Takuya applies this to software: treat your core development environment (editor, AI coding agent, or framework) as the rice — the constant that never changes — and allow yourself only one primary tool and one secondary tool. The goal is to create a rhythm where you can return to a comfortable, heart-centered place.

Practical Takeaways

• Decide what NOT to do. Doi says: “By simplifying meals to Ichiju Issai, cooking becomes free of stress.” Your tech stack should follow the same rule.
• Find tools you never get bored with. Just as a parent’s cooking brings comfort through familiarity, your core tools should feel like home.
• Avoid tracking gossip or drama. Social media algorithms try to grab attention; Takuya advises deliberately ignoring them to preserve calm.
• Direction over strategy. Moats can be flexibly changed; the important thing is knowing where you want to go as a developer and artist.
