■ Background and Challenges

According to a survey by the Ministry of Land, Infrastructure, Transport and Tourism, approximately 64.3% of businesses in the real estate industry responded that improving operational efficiency is an urgent task. Meanwhile, another survey shows that over 30% of prospective tenants are lost to other properties due to delays in initial response, clearly indicating that the speed of inquiry response directly impacts the closing rate.

However, in reality, many real estate companies continue to rely on phone calls and human effort for inquiry response. Inquiries received outside business hours are often left unattended until the next business day, and even during business hours, sales representatives are often too busy with property viewings and contract work to make immediate calls. Hiring an inside sales representative solely for inquiry response incurs a cost of 300,000 to 500,000 yen per person per month.

"Inquiries are coming in. But there's no one to make the calls."

This is the biggest pain point for real estate company executives.

■ What is 'Hanyo AI Call-kun'?

'Hanyo AI Call-kun' is an AI voice service specializing in real estate inquiry response that detects inquiries from real estate portal sites in real-time and has AI make immediate calls and engage in conversations.

Traditional inquiry response outsourcing services have limitations in response speed and operating hours because human operators make the calls. 'Hanyo AI Call-kun' uses a fully autonomous AI that combines speech recognition (STT), large language models (LLM), and speech synthesis (TTS) to handle phone responses, enabling the first outbound call within a minimum of 30 seconds from inquiry generation, 365 days a year.

■ Key Features

1. Immediate Outbound Calls for Inquiries

Automatically detects inquiries from portal sites such as SUUMO, HOME'S, and At Home. AI starts making calls within a minimum of 30 seconds from the inquiry, even outside business hours or on holidays.

2. Conversational AI Optimized for Real Estate Sales

Equipped with conversation flows necessary for real estate inquiry response, such as hearing desired property conditions, adjusting viewing schedules, and providing information on surrounding areas. It converses in natural Japanese indistinguishable from a human.

3. 365-Day Operation, Zero Missed Opportunities

Responds immediately to inquiries on holidays and Sundays. Prevents customer churn caused by "calling back on the next business day."

4. Automatic CRM Integration

Call content is automatically recorded in HubSpot and Salesforce. Sales representatives can start follow-up simply by checking the list of pre-qualified leads the next morning.

5. Overwhelming Cost Advantage

Compared to hiring one inside sales representative (300,000 to 500,000 yen per month), 'Hanyo AI Call-kun' can start from tens of thousands of yen per month. This significantly reduces the cost of inquiry response.

■ Future Outlook

Rabona AI Co., Ltd. aims to support humans in focusing only on essential tasks, not only with phone AI agents but also by addressing customer support operations currently handled by call centers and through real-time AI video agents.
