Home Energy Assessment · ¥22,500
See your home's energy
clearly, without the noise
A two-hour on-site session maps how your household actually uses energy across a typical week. What follows is a written summary you can return to — no sales pitch, no pressure to act.
Back to HomeWhat this offers you
A clearer picture of where your energy actually goes
After this session, you'll have something most households don't: a calm, informed view of how energy moves through your home across a typical week. Not estimates from a utility bill — actual observations, shaped by someone who understands seasonal patterns in Japanese homes.
The written summary you receive five business days later is yours to keep and read at your own pace. Some people use it to have a more informed conversation with a contractor. Others simply find the clarity useful. Either way, you leave with more than you came in with.
Honest observations
What we find is what we share — including the parts that are already working well.
Seasonal awareness
Japanese homes have distinct patterns across the year. Our notes reflect that context directly.
No follow-up obligation
The session stands on its own. You decide entirely what, if anything, to do next.
What brought you here
Something about your energy use has started to feel unclear
Maybe the bills have crept up and you can't quite trace why. Maybe you've been meaning to look into insulation or hot water but haven't known where to start. Or perhaps you're simply aware that your home uses more than it probably needs to, but daily life hasn't left room to investigate properly.
These feelings are common, and they tend to sit quietly in the background — not urgent enough to act on immediately, but persistent enough to surface whenever a bill arrives or the seasons shift. What's missing isn't motivation. It's usually just a clear starting point.
That's what this session is for. A calm, unhurried look at your home with someone who can make sense of what they see.
Common situations people bring to this session
-
Heating and cooling costs that seem high relative to the size of the home
-
A sense that appliance habits could shift, but no clear sense of where to start
-
Wanting to reduce usage before beginning a renovation — not after
-
Moving into an older property and wanting to understand what you've taken on
-
Awareness of available rebate programmes but uncertainty about whether they apply
Our approach
A methodical walk-through, conducted at a calm pace
We arrive at your home and spend two hours observing how energy flows through the spaces you actually use. This includes the kitchen, hot water arrangements, insulation condition where visible, and any appliances or heating systems running in the background. We note seasonal context — the time of year, your building type, and regional patterns that affect interpretation.
We don't come with a checklist that rushes through rooms. We spend time in spaces that matter most to your usage pattern, and we ask questions that help us understand the habits behind the numbers. You're not required to prepare anything in advance.
Arrival and overview
We begin with a brief conversation about your household's routines and any areas of concern you've already noticed.
Systematic observation
We move through the home at an unhurried pace, noting insulation, ventilation, appliance habits, and hot water systems.
Contextual notes
Seasonal patterns and regional rebate programmes are considered alongside what we observe in your specific property.
Written summary
Within five business days you receive a clear document outlining observations, gentle suggestions, and relevant reference information.
What it feels like
An unhurried morning or afternoon, followed by a document you'll actually read
Most clients describe the visit itself as surprisingly relaxed. There's no formal structure to adhere to, no presentations to sit through. We walk the home together, pause in rooms that seem relevant, and talk through what we're noticing as we go. Questions are welcome throughout.
After we leave, the next few days pass normally. Then the summary arrives — written in plain language, without technical jargon or dense tables. It reads more like a considered letter than a report. You can sit with it for as long as you like before deciding anything.
Some households find that the clarity itself is enough. Others use the document as the starting point for a renovation conversation, or to explore the rebate programmes we reference. Both responses are entirely valid. There is no expected outcome beyond understanding your home a little better.
No need to tidy or prepare the home beforehand
Questions welcome at any point during the visit
Written summary in plain language — no jargon
Yours to keep — no expiry, no follow-up agenda attached
Investment
¥22,500 — a single, transparent fee
The price covers the full two-hour on-site visit and the written summary delivered within five business days. There are no add-on charges and nothing to subscribe to.
For context: regional rebate programmes we commonly reference during assessments can offset ¥50,000 or more in qualifying upgrades — which means the session often repays itself many times over simply by surfacing options that were already available but unknown.
Payment is arranged before the visit date. If a scheduled visit needs to change, we ask for at least 48 hours' notice and will find a time that works for you.

Homeowners and long-term renters who would like a clearer picture before making changes. No prior knowledge of energy systems required.
How we work
An approach shaped by observation, not assumption
Observation-first method
We record what we see rather than drawing conclusions from averages or benchmarks. Your home is treated as its own system.
Seasonal context applied
Hot water use patterns, insulation behaviour, and heating load vary significantly by season in Japan. Our notes account for this directly.
Practical reference list
Where relevant, we include a short list of rebate programmes available in your prefecture — not a comprehensive directory, but a useful starting point.
Plain-language writing
The written summary uses everyday language. No engineering terminology, no requirement for prior knowledge of building systems.
Realistic timelines
The summary arrives within five business days. We don't rush the write-up; it's one of the parts clients find most useful.
Gentle suggestions only
Our summary outlines options for consideration — not a ranked list of urgent actions or a case for any particular product or service.
Our commitment
You'll receive a document that reflects your home honestly
We won't claim the visit will produce a set amount of savings or a specific reduction in usage. Those outcomes depend on decisions and circumstances that sit outside our work. What we can commit to is a thorough, honest assessment and a written summary that reflects what we actually observed.
If you feel the summary didn't address your home thoughtfully, we're willing to revisit specific points in a follow-up conversation. We'd rather take the time to get it right than leave you with questions.
There's no obligation attached to contacting us. An initial conversation to see if this service fits your situation is always welcome — and always without any expectation on either side.
A note on expectations
We approach this work as a service to your household's understanding — not as a sales process. The summary is yours regardless of what you decide to do with it.
