Partnership and contract services
We respond flexibly across requirements organization, design, implementation and operations improvement — scaled to the work and the organization.
The goal of design isn't just delivery, it's an arrangement the business actually settles into.
System development
We split requirements into small slices and ship a working minimum system first, absorbing real-world drift as we improve.
RPA deployment support
Automation starts small and improves with on-site exceptions and operations in mind. Reliability over breadth.
Business and practical support in Japan (for foreigners)
We work with you as the Japanese-side operator for procedures, paperwork, and coordination when starting business or deals in Japan.
Business workflow improvement
We visualize the current state and start with the smallest change that yields a measurable effect, then verify in operation and expand only as needed.
Website development
We ship the smallest configuration that directly serves your goal, then watch response and operations to improve it.
Short-form video production
We produce short-form videos for social media and ads, starting from a small, workable format, then refine scripts and editing based on real response and build a setup you can keep running.
We carefully listen to the work and the on-site constraints, leverage existing cloud services or off-the-shelf software for the parts they cover, and only build the parts they can't. Operations, cost and security feed into the choice between cloud, on-prem or hybrid — we propose the shape that requires the least friction.
Not sure which one fits? Just tell us where things stand.
Strengths and stance
We design around "will it actually be used" and "can it be sustained".
Goal-first thinking with the right means
We build the minimum configuration tied directly to your goal and weigh whether the result is something operation can keep using. Off-the-shelf options are considered when appropriate.
Verify and iterate with an MVP (minimum viable unit)
We're good at building a minimum viable unit and improving it as we watch how it gets used.
A nimble project setup
A full-stack engineer handles everything directly, from first contact through design, implementation, and operation — nothing gets lost in hand-offs, and we stay flexible about structure, process, and contract shape.
How we work
Six steps focused on building small and improving while operation takes hold.
- Discovery (current state, goals, constraints)
- Visualization (operations and data flow)
- Fit & gap (matching requirements with the current state)
- Design (KPI definition, screens, scope)
- Implementation (BI / RPA / website / system)
- Operation (improvement cycle, handover)

Frequently asked questions
The points people most often check before reaching out.
Are there reference price ranges?
Operations organization or architecture review alone starts from a few tens of thousands of yen; deployment support around existing tools is roughly tens of thousands to over a hundred thousand; small-scale development starts in the low hundreds of thousands. Full-business system development is quoted per project.
What areas do you serve? Can I request work from outside Tokyo?
We are based in Minato City, Tokyo. We can meet or visit on-site (in Japanese), within Tokyo and Saitama Prefecture, depending on the content. Since we also use web conferencing in Japanese, clients outside Tokyo or further away can request work regardless of location.
Since this is run as a side business, what about turnaround times and response speed?
We mainly work weekday evenings and on weekends. This means we're not a good fit for short deadlines or projects that rely on a large workforce, but with advance scheduling we can also accommodate daytime web conferences and on-site visits (in Japanese). We aim to reply to inquiries within 2 business days as a general guide. By proceeding in stages, we propose a structure that keeps initial cost and risk down.
Is the first consultation free? What should I prepare?
Yes, the hearing is free. It's enough to bring three things: your purpose (what you want to solve), your current situation (existing operations and tool setup), and your desired timing — your challenge doesn't need to be fully defined yet. Sharing constraints such as security requirements and a sense of budget also helps improve the accuracy of the estimate.
About HoshimonoDesign
HoshimonoDesign is a sole proprietorship that restructures on-site operations and delivers system development, automation and visualization by building small and improving in production.
We organize the issues in existing work and shape them with the most appropriate means. A full-stack engineer and project manager with the PMP (Project Management Professional) certification shares the reasoning behind decisions and risk responses, guaranteeing both process and quality.
We are on the side of teams dealing with siloed tasks and too much manual work.
We offer wide-ranging options, including recommending existing products.
Based in Tokyo, we support both on-site visits and online meetings (in Japanese).
Expected outcomes
While staying mindful of cost and time-to-effect, we share the reasons behind decisions and design intent so you can decide without anxiety.
Reduced mental load
Quiet the "is this really okay?" worry so the work can move forward with conviction.
Fewer rework cycles
By sharing the decision criteria up front, the time lost on re-confirming, explaining and re-doing work goes down.
An improvement cycle that sticks
By visualising numbers and the situation, improvement keeps running on evidence instead of gut feel.
Availability and communication
Because we operate as a side business, primary availability is weekday evenings and weekends. Web meetings and on-site visits (in Japanese) are arranged in advance.
We keep costs in check while emphasising design and incremental implementation, so the approach and schedule are aligned carefully during the initial consultation.
Even if the brief is still fuzzy, you can start with a free consultation
Share your current situation briefly and we'll come back with a way forward and a rough cost range.
