Profile

A practice shaped by science, visual communication, and software.

Current base Sydney, NSW

Working across product concepts, web and app interfaces, multilingual UX, and visual media.

Study University of Sydney

Bachelor of Science student at the University of Sydney, combining Medical Science, Visual Arts, data analysis, and visual communication.

Languages Japanese / English

Native Japanese speaker with professional English, including practical interpretation, translation, and localization experience.

Approach

Build small, explain clearly, and use visuals to think.

I keep projects practical: define the problem, shape the interface, build a usable version, then explain the decisions behind it.

Build

Turn concepts into working products.

I treat app and web projects as complete systems across user flow, interface, implementation, content, and release.

Localize

Treat language as part of the product.

My Japanese-English work connects multilingual product strategy with details like furigana, pinyin, IPA, and context-aware copy.

Visualize

Use image, motion, and space to clarify ideas.

Visual studies, 360 video, and photography help me test composition, pacing, attention, and atmosphere alongside product work.

Selected work

Products, localization, and visual studies.

Selected pieces that show how I design, build, localize, and explain ideas.

Midnight Laundromat

A 360-degree waiting-room environment developed from initial proposal through visual direction, sound-led pacing, and final MP4 delivery. It turns a simple waiting concept into a finished spatial media piece.

Case Study

  • Mixed reality study
  • 360° equirectangular
  • 2025

A 360° space
where waiting
becomes physical.

Problem

How can a simple 360-degree scene make waiting feel physical without a fixed camera or heavy plot?

Approach

Repeated machine forms, rain, fluorescent light, warm dryer color, footsteps, and ambient audio guide attention.

What it shows

Concept iteration, visual direction, production pacing, and clearly explained creative decisions.

VR experiment

  • Spatial study
  • 360° loop
  • 2025

Immune system
as a 360° field.

Intent

Translating cellular interaction into an immersive volume the viewer can stand inside.

Outcome

A short 360-degree loop where scale, motion, and proximity carry the story without narration.

Portfolio blog

Short notes on product, language, and shipping.

Translation is a product problem

Good localization is more than text conversion. It connects intent, interface, search, support, and user trust.

Hospitality as a UX lab

Local restaurants expose practical multilingual problems: menus, booking flows, staff phrases, FAQs, and discovery.

AI-assisted shipping needs judgement

AI can speed up drafting, coding, and research, but final quality still depends on constraints, review, and taste.
