Google

Customer Engineer at Google Cloud (AI & AppMod) | Japan Tech Team (Data & AI) | Full-Time | Apr 2023 - Present | Japan

Generative AI, AI Agents, Data Analytics, Cloud Migration

  • Support enterprise customers across all aspects of Google Cloud adoption — leading technical PoCs and strategic architecture proposals that span cloud migration, Generative AI, and AI Agent implementation, bringing a researcher's background to problem-framing and logical reasoning.
  • Technically led a large-scale (2,000+ seats) enterprise rollout of an AI-powered coding-assistance tool, and moved a multi-million-dollar cloud migration forward through detailed cost estimation and technical validation.
  • Designed and implemented AI Agent solutions that automate expert-dependent, tacit-knowledge processes — including test-planning automation for mission-critical systems — and led hands-on builds of RAG-based enterprise search agents with the Agent Development Kit (ADK) and Agent Engine.
  • Developed several new Generative AI delivery offerings, including secure enterprise NotebookLM adoption, a video-analysis AI solution, and unstructured-data (document/image) structuring pipelines built with Document AI and Gemini.
  • Drove technical enablement through 20+ customer workshops and hands-on sessions per year with consistently high customer satisfaction, and contributed to the technical community as a GenAI tech-blog reviewer and a BigQuery ML hands-on instructor.

Pixie Dust Technologies, Inc.

R&D Engineer | Part-Time | May 2020 - Mar 2023 | Japan

Python, JavaScript (AngularJS), HTML, CSS

  • As the lead engineer, implemented one of the largest accessibility-friendly questionnaire websites, featuring mouse tracking, VoiceOver, and alt text. Conducted an in-depth web-based survey on online shopping and e-commerce with 133 visually impaired participants, and clarified serious issues among them (e.g., difficulty buying and selling goods via apps, and recognizing product images, textures, design, and size).
  • Published research paper [3] and press release with Mercari, Inc., one of the world’s biggest flea market companies, and contributed to future research on accessibility, inclusivity, and diversity, particularly for visually impaired people, by sharing the thorough survey results and insights.

Rakuten Group, Inc.

Product Manager | Internship | Feb 2021 - Apr 2021 | Japan

User Research, Market Research, PRD, Usability Test

  • Created a product concept covering market, personas, problem, solution, and competitor analysis. Identified a critical gap in current OTAs — the lack of end-to-end confirmability of hotel accessibility — by uncovering user pain points through research with nine elderly and low-mobility participants, then validated new accessibility features that eased OTA hotel booking through usability tests.
  • Key takeaways: 1. Focus on the real issue by finding the root cause behind users' deep pain points. 2. Keep asking 'Why' about the product to avoid the build trap. 3. Learned practical problem-solving that balances tech, business, and UX by observing other PdMs' meetings and discussions.

Projects

ElectroMagnetic Guitar: Chord Playing Support System on Guitar by Electromagnets

Academic | Apr 2019 - Mar 2020 | First author | Two project members

⚠️ Problem:
It is difficult for beginner guitar players to play chord properly because of the complexity of left hand shape for string pressing on guitar.

💡 Solution:
We made ElectroMagnetic Guitar (EMG) with an original fretboard with controllable electromagnets mounted and attached it to the normal classic guitar. EMG ‘draws’ player’s left hand fingers with magnetic material attached toward proper chord positions on the fretboard. As a result of an informal user study, our EMG prototype offered sufficient magnetic force to keep chord form, though not enough power to properly draw fingering.

A Picking Interface Seamlessly Connecting Passive and Active Performance on Guitar

Academic | Apr 2019 - Mar 2020 | First author | Two project members

⚠️ Problem:
There are limited ways to handle multimedia such as CG and music effects while playing musical instruments naturally.

💡 Solution:
We have designed an interface that allows a guitar player to manipulate another channel, such as the manipulation of visual effects, while playing the guitar and immediately reflects the performer's intentions without turning away from the guitar playing motion. We proposed a method to distinguish 3 picking states (Chord stroke/Single note/Non-picking) by sensing pressure on the pick and the rotation angle of the player’s index finger. Our brief experiment showed that our method can correctly identify the picking state with high accuracy.

Auditory-centered Vocal Feedback System Using Solmization for Training Absolute Pitch without GUI

Academic | Jun 2020 - Sep 2021 | First author | Five project members

⚠️ Problem:
Most current training systems and applications for absolute pitch acquisition have focused on providing visual feedback. However, many people having perfect pitch describe that they hear music as words rather than envisioning visual notes.

💡 Solution:
This study proposes an auditory-centered training system using solmization to artificially acquire and train absolute pitch by providing vocal feedback of musical notes through a musician’s voice. Furthermore, our proposed system does not require a Graphical User Interface (GUI), in contrast to traditional training systems, such as tuners and the visualized guide melody of Karaoke. In an experiment with 10 participants, our system’s training with vocal feedback improved six non-potential ab- solute pitch users’ absolute pitch by approximately 25%, although extant system with visual feedback didn’t make an improvement.

Shokyu

Business | Dec 2020 - Present | Founder | Three project members

⚠️ Problem:
English speakers living outside of Japan have few opportunities to learn authentic Shodo from Japanese instructors. Plus, some of them have no access to Shodo tools such as brush, paper, ink, and underlay.

💡 Solution:
Shokyu provides opportunities for English speakers to learn calligraphy online while living abroad.

Momentary English

Business | Dec 2020 - Present | Founder | Sole project

⚠️ Problem:
As a tendency of English skills, Japanese can read, write, and listen to some extent, but are not good at speaking. The problem is that the training to convey what you want to say instantly in English is not enough, and the English composition circuit is not built in the brain.

💡 Solution:
We have developed a website that allows training to instantly translate Japanese sentences into English by diverting the flash mental arithmetic method. By continuing this training, users can build an English composition circuit in the brain to tell what they want to convey smoothly in English. With Momentary English, you can efficiently train English speaking from your smartphone or computer, although there are already books for momentary English composition. Furthermore, the system of this website is applicable for other languages and other memorization subjects.
