When you start a vacation rental business, the first wall you hit is the complexity of operations.
Airbnb, Booking.com, Rakuten Travel. Listing properties across multiple platforms, preventing double bookings, instantly replying to guest messages, coordinating cleaning staff, optimizing pricing. Try to do all of this manually, and things start falling apart once you go beyond three properties.
That's why you need a property management system (PMS). But for Japanese vacation rental owners, the available tools have had a long-standing problem.
International tools have inadequate Japanese support, domestic tools are expensive. And neither comes close to AI-powered automation.
We set out to solve this problem along three axes: "Free x AI x Japanese." That's StayFlow.
500 Properties Adopted, 4.9/5 Satisfaction
StayFlow launched in 2025 and has now been adopted by over 500 properties. Customer satisfaction is 4.9 out of 5. We believe this score reflects not just the tool itself, but the result of real-world, day-to-day use on the ground.
Why is it being chosen? The reasons are clear.
First, it's free to start. Zero upfront cost, zero monthly fees. Property management, reservation management, and guest management -- all the core features are available at no charge. The barrier to "just try it out" is as low as it gets.
Second, AI handles the real work. Features like AI auto-replies to guest inquiries and AI-driven dynamic pricing suggestions let you hand off tasks that humans shouldn't have to do. When a guest asks "What's the Wi-Fi password?" at 2 AM, the AI responds instantly.
Third, it's fully Japanese-native. Menus, notifications, reports, and even the guest portal -- everything is in Japanese. This might seem obvious, but anyone who's tried using an international PMS knows exactly how valuable that is.
Beds24 Integration: Freedom from Manual Syncing
Integration with Beds24, the channel manager used by many vacation rental owners, is another one of StayFlow's strengths.
Property information, reservation data, and guest message syncing are already implemented -- changes made in Beds24 are automatically reflected in StayFlow. On top of that, real-time sync via webhooks is scheduled for completion in March. This will completely eliminate the double-entry of "check Beds24, then manually input the same data into StayFlow."
enabler.fun — Proving It on Our Own Properties
We're not just the ones building the tool -- we're also the ones using it.
Through enabler.fun, we operate five properties, including an ocean-view villa in Atami, a natural hot spring lodge in Teshikaga, Hokkaido, and a beachfront house in Honolulu. We manage all of these properties with StayFlow, refining the product as our own most demanding users.
The Future of Vacation Rental Management Is "AI x Free"
Japan's vacation rental market continues to grow alongside the recovery of inbound tourism. For new owners entering the market, expensive management tools are a barrier to entry in themselves.
StayFlow removes that barrier. Free to start, AI to handle the tedious work, and everything in Japanese from end to end.
Five hundred properties is just the beginning. Our goal is to become the tool that Japanese vacation rental owners choose first and keep using to the very end.
If you're struggling with vacation rental management, start for free. AI will transform your operations.
