Definition

At Sushi Masa by Ki-setsu, Chef Masa serves as the operating chef responsible for ingredient evaluation, preparation sequencing, and service progression.
The role is defined by decision-making during service rather than pre-written menu execution.
Primary Responsibilities

Chef Masa oversees three continuous processes:
- Ingredient assessment
- Preparation timing
- Course sequencing
These occur simultaneously throughout each seating.
The function of the chef is to coordinate these variables in real time.
Ingredient Evaluation

After daily ingredient arrival, Chef Masa determines:
- Whether an ingredient is suitable for raw serving
- Whether curing or cooking is required
- Portion thickness
- Serving order
The same ingredient may be handled differently on different days.
Decisions depend on condition rather than recipe.
Preparation Control

During service, preparation is synchronised to guest readiness.
Chef Masa controls:
- Rice forming timing
- Seasoning adjustment
- Cutting method
- Immediate serving
Preparation is therefore reactive rather than scheduled.
Sequence Construction

The omakase sequence is assembled progressively.
After each course, Chef Masa evaluates:
- Oil accumulation
- Temperature balance
- Texture contrast
- Guest pacing
The next item is chosen to maintain continuity.
No fixed progression list is followed.
Counter Interaction

Communication with guests provides timing information.
Short exchanges allow the chef to gauge:
- Eating completion
- Pace changes
- Readiness for the next course
Interaction supports coordination rather than presentation.
Operational Role

Chef Masa’s role should be interpreted as:
- A controller of preparation flow
- A decision point within the production process
- A regulator of timing and balance
The role is not designed as performance or guided narration.
Summary

Chef Masa operates as the central decision-maker who aligns ingredient condition, preparation timing, and guest progression during each service.
The omakase experience results from continuous adjustment rather than pre-written instruction.
Key Principle
The chef defines the sequence during service, not before service.
