About HoshimonoDesign

HoshimonoDesign is not a business built to sell a specific product or technology. We carefully organize the work and the requirements, then design the shape that fits the current situation with the least friction.

On-site we've often seen tools and systems get ahead of vague requirements, only to stop being used.
Usually it's because what to solve and how far to go weren't organized enough, or because the existing work simply doesn't bend to fit the application.

So in this practice we organize the work and constraints first, then decide whether existing tools suffice, what to build, and what to combine.
We don't build more than necessary and we don't pick unneeded configurations.

Because this is a side-business operation, we can't run on tight deadlines or labour-intensive approaches. In exchange, progressing in stages lets us propose configurations that keep cost and risk in check.

It suits teams that value the conviction behind decisions and a design that won't trip them up later — more than raw speed.

Business overview

  • Trade name: Hoshimono Design
  • Business: software planning, design, development and maintenance
  • Local AI deployment support (AI that keeps data inside your organisation)

Base and service area

HoshimonoDesign is based in Minato, Tokyo.
On-site visits and meetings (in Japanese) are available in Tokyo and Saitama Prefecture, as appropriate.

Web meetings (in Japanese) let us communicate flexibly regardless of location.
We suggest the best mode based on the project and how it should progress.

Operator

A PMP-certified full-stack engineer handles everything — client communication, requirements, front end, back end, infrastructure, and operation. The person you talk to is the person who builds it, so nothing gets lost in translation. As a sole-proprietor product studio, we own design, implementation and operation for the quality bar of real work. We keep users in a state where they can see and manage their own data, and we clearly explain why we choose configurations that don't send data outside.

Technology stack

A stack tuned for landing things into operations — from the upstream design of business improvement to automation, data activation, web development and BI.

Business improvement / design (upstream)

  • Requirements definition / specification organization / acceptance design
  • Project management (the operator holds the PMP certification)

Local AI deployment (on-premises AI)

For workplaces that cannot send data to the cloud, we deploy AI that runs on in-house PCs alone.

  • Speech transcription and summarisation (already in production in our own product)
  • Selecting AI models to match the use case and the PC specs (including checking the developer and its country)
  • Explanatory material for security teams (which models are used, whether anything goes over the network)
  • Procedures for rolling out and updating across multiple machines

Automation and development (Automation / Engineering)

  • RPA: routine-task automation, workflow design, componentisation
  • Excel VBA: aggregation, reports, transfers, bulk processing — general business macros

Data analysis and visualization (BI / Analytics)

  • BI: KPI design, dashboard construction, update design that assumes operation
  • Python analysis: data wrangling, validation, automated report generation

Web service development (Full-stack)

  • Frontend: Next.js / TypeScript
  • Backend: FastAPI (Python) / MariaDB
  • Operations: VPS setup, Nginx, automated deployment

Maps and public data (GIS / Open Data)

  • Ingesting hazard maps, real-estate transaction prices and public transport data
  • Scheduled updates and automated quality checks

Web (within the necessary scope)

  • WordPress
  • Full custom development: requirements through implementation (including business tooling and small-scale systems)
Optional, on request

Financial data

  • Stock and FX data fetching / analysis (Python / automation)
  • MT4 / MT5 customisation
