From concept to continuous improvement.
With a production workflow built around generative AI,
I help small and mid-sized businesses move their digital marketing forward.
What matters most is not how beautiful a design looks,
but whose problem it is meant to solve.
For nearly two decades, I have worked across sales, frontline operations and corporate functions,
working on KPI design, process improvement and organisational coordination.
When I began working with design, I realised
that design is not simply about appearance; it is about how things are structured.
My AI-enabled production workflow
is a practical extension of that idea.

Case Study
CASE STUDIES
CASE 01
Brand Film / Current Study
SHINSAN DESIGN — Seedance × Premiere
Challenge
A short brand film expressing SHINSAN DESIGN’s approach, where AI, design and implementation work as one continuous process. Multiple shots were connected into a coherent sequence while preserving the visual language of the source images.
AI Direction
Each shot was generated separately in Seedance from a reference image. Instead of generating one long sequence, motion, camera behaviour and restrictions were specified shot by shot, then the most stable results were selected and edited.
Building on the earlier CASE 02, the workflow evolved toward reference-led visual direction, shot-level control and deliberate post-generation editing. The evolution of the AI video-production process is documented as part of the work itself.

CASE 02
Brand Film / Early AI Motion Study
SHINSAN DESIGN — Gemini Era
Starting Point
An early experiment in bringing generative AI into video production. Generated material and editing were combined to communicate the brand direction through motion rather than words alone.
AI Workflow
Visual material was generated with Gemini, while ChatGPT and Claude were used to structure the narrative and copy. Premiere was then used for cutting, typography and direction, rebuilding the material as a brand film for the web.
Process
Concept → Structure → AI Asset Generation → Premiere Editing → Typography & Timing → Web Delivery
Learning
This early work became the starting point for CASE 01, which introduced reference images, shot-level control and short segmented generations. The portfolio records not only finished work but also how the production method itself has evolved.

CASE 03
Recruiting LP / Live Prototype
Manufacturing / Recruitment & Corporate Communication
Business Issue
Job listings alone often fail to communicate the work, culture and potential for growth after joining. The experience was redesigned around the candidate decision journey so visitors could picture themselves working there.
Hypothesis / Solution
Rather than presenting information in the company’s preferred order, the site follows the candidate’s questions: company values → role → workplace → onboarding journey → FAQ → application, implemented as a responsive website.
Process
Research → Candidate Journey → Information Architecture → UI Design → HTML / CSS / JavaScript → Responsive Design → Interaction Implementation
Outcome
Recruitment problem definition, design, AI use and front-end implementation were connected in one workflow, resulting in a live prototype where the full journey from browsing to application can be experienced.
An experiment in AI-led education and training content, testing whether a presenter, device interaction and information display could work together as one coherent video.
AI Direction
Generated in Seedance from a character reference, with a focus on human performance and device interaction while separating areas where generative AI performs well from fragile areas such as text and UI.
Process
Character Design → Reference → AI Video Generation → Shot Selection → UI & Text Review → Premiere Editing → Web Delivery
Learning
Presented as a practical example of AI video direction: generated output is treated as source material, usable expressions are selected, and human editing is used to bring the work to a publishable standard.

AI Creative Experiment / From Generation to Direction
Seedance 2.5 — Exploratory Generation Study
Experiment
A 15-second experiment built from the abstract theme “SHINSAN DESIGN” and only minimal direction, leaving much of the visual narrative to the AI. It explores how the model constructs a brand image through people, data and collaboration.
What Emerged
The result produced unexpectedly strong visual ideas, but also unintended UI text, brand elements and inconsistencies. The first-generation state is deliberately shown to document what happens when more creative discretion is given to the AI.
Refinement Workflow
GENERATE → SELECT → REFINE → EDIT → DELIVER. Rather than accepting generated output as a finished product, usable shots are selected, references, regeneration or partial fixes are applied where needed, and timing, sound, transitions and typography are rebuilt in Premiere.
Learning
Where CASE 01 designs first and then controls the AI, this experiment lets the AI explore first and has a human evaluate and edit afterwards. It treats generative AI as a source-material engine and turns the human process of judgement and direction into the case study itself.
Tools
Seedance 2.5ChatGPTPremiere
The video intentionally retains elements from the first-generation state. Selection, regeneration and software editing after generation are considered part of the AI creative-production process.

Each piece includes the intent that shaped its design direction.
The work shown here was produced with workflows that incorporate generative AI.
Live Web ExperienceLIVE LANDING PAGES
These concepts go beyond static design proposals. Information architecture, UI and interactions are adapted to each objective and implemented as working HTML / CSS / JavaScript websites.
Recruiting / Employer Branding LP
Recruiting — Anxiety Reduction
Instead of listing job conditions, the page follows the candidate’s decision sequence across role, workplace, onboarding and FAQ, gradually reducing uncertainty before application.
Designed for two audiences—students and parents—with a journey from recognising the learning challenge to comparing courses, building parental confidence and booking a free trial. Includes course switching and a booking demo.
Built around trust, which is critical for intangible services: problem recognition → support areas → outcomes → self-assessment. Includes service tabs and a three-question diagnostic to help visitors understand their needs before making contact.
Designed to create emotion before explaining conditions, moving from travel atmosphere to plan comparison, itinerary and booking. The implementation also allows the hero area to be replaced with AI-generated video in the future.
Creative ExperimentsDesign the expression from a hypothesis.
Even with the same objective, creative changes depending on the entry point. Six hypothetical briefs were developed as A/B creative hypotheses, considering not only CTR but also downstream behaviour and lead quality.
01
EC / CONVERSION
Turn product appeal into purchase intent.
AB
TEST AXIS — Local Value / Food Experience
A communicates origin and regional value; B leads with appetite and sensory appeal. The test asks which entry point is stronger from awareness through purchase.
02
BtoB SERVICE / LEAD GENERATION
Clarify service value and turn interest into enquiries.
AB
TEST AXIS — Product Value / Brand World
A shows concrete value; B creates interest through brand atmosphere. The evaluation considers lead quality as well as volume.
03
BRAND / AI・DX

AB
TEST AXIS — Future Resonance / Willingness to Challenge
A starts with emotional resonance; B stimulates ambition and growth. Success is considered in terms of fit as well as application volume.
05
CORPORATE / BACK OFFICE DX
Make operational problems feel relevant and encourage action.
AB
TEST AXIS — People / Work Systems
A focuses on reducing human workload; B visualises changes in the system. The test distinguishes problem-aware audiences from solution-seeking audiences.
06
SALES PROMOTION / ACTION
Drive visits, purchases and participation through campaigns.
AB
TEST AXIS — Product Experience / Promotional Incentive
A creates desire; B creates a reason to act now. The comparison balances brand value against short-term conversion.
AI Movie / Selected WorksAI VIDEO / EDITING
Short-form video for social and web use. Generative AI is used as part of shooting and asset creation, while structure, selection and editing remain human-directed. Rather than publishing raw short generations, multiple shots are selected and connected, then music and fades are rebuilt in Premiere into a coherent web-ready film.
Café Promotional Film
INTENT
For a physical venue, atmosphere can be part of the reason to visit. The film focuses on steam, reflected light and tactile detail so the comfort of waiting for a cup is felt before the menu is explained.
Company Culture Film
INTENT
A recruitment and communications short built around an everyday moment between colleagues. Rather than conditions or benefits, the aim is to create the feeling: “I would like to work with these people.”
Travel Promotion Film — Shizuoka
INTENT
Travel promotion often benefits more from immersion than information density. Instead of explaining the itinerary, the film offers a preview of the memory of travelling there, designed to create desire.
Business Improvement Service Film
INTENT
An explainer for an intangible service, structured around a Before → After contrast so viewers can picture the operational change after adoption.
