AI × MARKETING × PRODUCTION
NEXT VALLEY is a Japan-based team that puts AI to work for small businesses.
From marketing to websites and landing pages, we recommend only what fits your goals —
and help you win more customers with less busywork.
Both are completely free. No pushy sales calls, ever.
PROBLEM
Neither your marketing nor your workload will fix itself while you're just winging it.
Do any of these ring a bell?
01
Website, social media, ads — you're doing a bit of everything, but none of it is really turning into inquiries.
02
The site you built ten years ago is still up, untouched. The face of your business is quietly costing you customers every day.
03
You'd love to use AI to save time, but you don't know where to start — and the daily grind leaves no room to figure it out.
04
You can't tell which efforts are paying off, so it's hard to get your team on board — or to justify next year's budget.
It's not your fault.
The people who build your website and the people who bring in customers are usually two different companies.
SELF CHECK
Not ready to talk to someone yet? Both tools below are free and need no sign-up. Send us the results on LINE and a pro will turn them into concrete next steps, at no charge.
SITE CHECK
If you already have a website
Answer 15 yes/no questions and get your web marketing score, plus the fixes to tackle first.
Start the site checkTakes 3 minutes. Results shown instantly.
AI CONSULT
If you don't have a website yet, or aren't sure where to start
The AI you already use (ChatGPT, Claude, Gemini, or Perplexity) asks you a few questions, helps you sort out your situation, and turns it into a Consultation Memo you can send straight to a specialist.
Takes 5–10 minutes, using your own AI account
Note: The AI assessment is not a NEXT VALLEY chatbot. The conversation stays between you and your AI, and nothing is sent to NEXT VALLEY automatically. Whether to share it is entirely up to you.
What we do
AI at the core, from marketing to production.
We won't try to sell you everything. We recommend only the moves your business actually needs.
AI CONSULTING
Want to use AI to work smarter but don't know where to begin? We use AI every day in our own production work, so our advice comes from practice, not theory. From choosing the right tools and training your team to redesigning your workflows.
WEB PRODUCTION
Websites and landing pages designed around who you're reaching, what you're saying, and how you'll say it. We work backward from results — not just from what looks nice. Website-only projects are always welcome. Building something new? Take a look at our free preview and see a design before you commit.
SEO / MEO
Get found in search results and on Google Maps by the people who are looking right now. We don't chase rankings for their own sake — we build a path that leads to inquiries.
SNS MARKETING
From Instagram and X to setting up and running your official LINE account. If “what should I even post?” sounds familiar, we'll take the whole plan off your plate.
DESIGN
Logos, flyers, brochures, banners — all your marketing materials from one team. Print and web that share the same look, so your message actually lands.
OPERATION SUPPORT
Our in-house tool lets you safely update your live website just by sending a chat message. AI drafts the change, and nothing goes live without your approval. Currently available to existing clients on request.
Why NEXT VALLEY
01
REASON
The people who plan your marketing are the same people who build and run it.
Nothing gets done in isolation — every move connects to a plan that leads to revenue.
02
REASON
We use AI daily in our own production and marketing, cutting builds that used to take a month down to as little as 3–5 days.
We hand you those same working methods — practical support, not theory.
03
REASON
Every month you get a report on traffic, inquiries, and other results.
No “it feels like things are better” — you can always judge by the numbers.

Start with a free site checkOur work
Over 50 businesses served, from real estate and construction to e-commerce, fitness, online media, and schools.
Education & Schools
They built exactly what we asked for, and with real care. I knew nothing about websites and had questions at every step, but they always answered kindly and patiently. They also came up with all sorts of ideas, and the site turned out even nicer than I'd imagined. I'm truly glad we asked them.
Education & Schools
It was our first website and I had no idea what I was doing, so I left almost everything to them — and they walked me through it one step at a time. They also suggested lots of ideas, and the site turned out even nicer than I'd imagined. I'm truly glad we asked them.
Education & Schools
Alongside the English school's main website, we built a landing page for their Eiken (English proficiency test) prep course, giving them two entry points for new students.

Launch is just the start. We keep improving your site based on real traffic and inquiry numbers.
From the founder
Hi, I’m Shun Kurabayashi, founder of NEXT VALLEY.
“It’s probably expensive.” “Will it actually work?” In our experience, those two doubts are what keep most people from reaching out.
So we show you the real thing first. We take a close look at where your business stands, then put together concrete recommendations and a quote — free of charge. If it’s not for you, just say no.
No pressure, no hard sell. Judge us on the substance of the proposal.
Founder, NEXT VALLEY Shun Kurabayashi
Common questions
We won’t promise “guaranteed results.” What we do instead is spell out, in the proposal itself, exactly what we’ll do, in what order, and which numbers we’re aiming for. After launch you get a report every month, so there’s never any ambiguity about whether it’s working.
Yes. Build-only projects are welcome. We only bring up marketing or AI if it’s genuinely relevant to you. “I just want a website for now” is a perfectly good place to start.
No. We never make sales calls. All communication is over LINE or email, and we won’t contact you out of the blue.
Absolutely. We explain things in plain language and help with everything from writing the copy to preparing photos. All you need to bring is your knowledge of your own business.
Of course. “I just want to know how to fix my current site” is reason enough to reach out. The proposal and quote are free.
Thanks to our AI-assisted workflow, a build that normally takes about a month can be done in as little as 3–5 days. If you’re on a tight deadline, let us know.
Yes, we work with clients anywhere in Japan. Everything happens online — LINE, email, and video calls.
