The name is Kenzo. I build websites that earn their keep.
Websites that show up when someone searches for what you offer — and then convert that visitor into a paying client. Design and SEO built together from the first line of code, not bolted on after the fact.
What that looks like in practice: your client opens their inbox to a lead who found you on Google — without a single ad spend. That is the only version worth building.

Why “BraneBox”?
In physics, a brane is a multidimensional object — a structure that doesn't exist on one plane but across many simultaneously. Most people hear “BrainBox,” which is fine too. But the spelling is deliberate.
Most digital problems look simple on the surface. A slow website is a design problem — until it's a hosting problem, a server configuration problem, a bloated JavaScript problem, or a content architecture problem. A site that doesn't rank isn't just “missing SEO” — it's missing technical structure, content depth, internal linking logic, and schema.
BraneBox is built to see all of it at once — package it into something clear and actionable, and execute without the overhead of an agency that turns every layer into someone else's department. For clients, that means working with someone who sees the whole problem, not just the piece their department handles.

I know what it costs to start a business.
I have started several. Not all of them made it.

Cafe PaManna — Quezon City
Cafe PaManna was a restaurant I opened in Quezon City. Within eight months we crossed one million pesos in gross sales. I ran everything: concept, design, menu, staff, marketing. It taught me that even with capital and momentum, businesses are hard. Business owners I have spoken to say the same thing — most need four to five years just to climb out of the deficit. Blood, sweat, and tears before the numbers stop being frightening.
BraneBox came after — founded and registered as a sole proprietorship in Nagoya, Japan on 27 February 2019, with almost no capital, working with clients like AXA Singapore and Hexagon Metrology Japan. Then COVID hit. Contracts stopped renewing, one after another. BraneBox became a sideline, not by choice but by circumstance.
I moved my family back to the Philippines for them. In Japan, we had no family close by — and when you have children, emergencies have a way of reordering your priorities.
Now BraneBox is the main focus again — operating from the Philippines. That history is not background noise. It is the reason every project I take on is treated as if it belongs to someone who cannot afford for it to fail — because most clients can't, and I know exactly what that feels like.
If your website is currently doing nothing for your business — no rankings, no leads, just a digital brochure nobody finds — I know exactly what that silence costs. And I know how to fix it.
Japanese precision. Filipino resourcefulness. 15+ years of SEO that actually works.
I am 75% Japanese. My father is half Filipino and half Japanese. My mother is from Yokohama. I grew up between two cultures and absorbed something from each that proves useful every day: the Japanese instinct to do things correctly or not at all, and the Filipino capacity to find a way when resources are scarce and conditions aren't ideal. In the Philippines we call the second one madiskarte.
I have a Bachelor of Science in Computer Science. I am not a designer who learned to code. I am a technologist who learned to build things people want to look at and use. That distinction matters when a site needs to be fast, crawlable, secure, and convertible — not just designed.
My SEO approach is not a checklist. It is a methodology built on one premise: write for people first, then make sure Google understands what the page is about. I ranked a personal website to number one on Google in 2007 and held it for sixteen years through every algorithm update — Panda, Penguin, Hummingbird, BERT, Helpful Content. All white hat. No shortcuts. The principle never changed even when the tactics evolved.
At GoWithGuide — the number one private tour company in Japan — I built the Marketing Team from scratch, created a content system that ranked articles on Google Page 1 within weeks of publication, earned backlinks from sites with Domain Authority 90 and above, and increased conversions by removing bottlenecks and adding strategic scarcity. Newsletter campaigns reached 45% open rates and 4% click-through — multiples above industry average.
A well-built site is not a cost — it compounds every month it ranks. Every month without technical SEO is a month your competitor is pulling further ahead.
That is the record. Not claimed. Demonstrated.

Some things the industry gets wrong.
Most web designers build websites and then add SEO. By then, it is already a compromise. Technical SEO lives in the structure of the site — in how pages are built, not in what you add after the fact. Every BraneBox project is built SEO-first. What that means for you: your site starts working toward page-one rankings from day one, not six months after launch when a consultant finds the structural problems.
A website without SEO is a store built in the middle of the desert. The interior can be beautiful. Nobody will find it — and invisible to Google means invisible to the clients you need.
SEO without technical SEO — just keyword optimization — is half a job. Google rewards pages it can crawl, understand, and trust. That means speed, schema, site architecture, and content depth. Keyword placement is the last 10%. What this means for your business: rankings that hold when Google updates its algorithm, because the foundation is correct — not because someone gamed the system.
On animation: more is not better. The purpose of a website is to communicate clearly and move visitors toward a decision. Excessive animation shifts attention from your message to the motion. Pages that communicate clearly and load fast convert better. That is the goal — and the reason BraneBox builds with intentional motion, not decoration.
Finding a web designer who genuinely cares whether your business grows is rare. Most are paid to deliver a site, not to care what happens after it launches. I am telling you plainly: I do. Every project is treated as if the business behind it cannot afford to fail — because most can't, and I will not pretend otherwise.
