Nippon Zaitaku Automates Lead Acquisition During Non-Operating Hours of Inside Sales, Securing an Average of 7 Leads Per Month

We are pleased to announce that "immedio," an AI inside sales solution provided by immedio Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Hideki Hamada; hereinafter "immedio"), which automatically increases qualified leads, has been adopted by Nippon Zaitaku Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; President: Tsutomu Shigeyoshi; hereinafter "Nippon Zaitaku").

Nippon Zaitaku is a company that develops real estate investment services for second-hand condominiums in Tokyo. It faced a structural challenge where, during nights and holidays when inside sales were not active, prospective customers' interest was high, but leads could not be converted into business opportunities. By introducing immedio's web engagement function to its private property viewing site in November 2025, Nippon Zaitaku established a mechanism to automatically generate leads even when inside sales personnel are not working. In just a few months since its introduction, approximately 40 cumulative leads have been acquired via web engagement, achieving high cost-effectiveness. Furthermore, by continuously improving popup wording and implementing immediate follow-ups right after bookings, they continue to pursue both the quantity and quality of business opportunities.

Background of immedio's Implementation

Nippon Zaitaku's inside sales team operates from 11:00 AM to 8:00 PM on weekdays. However, prospective customers often gather information after work, from 8:00 PM onwards, or during weekend nights, creating a significant mismatch with operating hours. Even if customers visited the private property viewing site when their interest was highest, inside sales could only approach them from the next business day onwards. During this time, their enthusiasm would wane, and valuable opportunities that could have led to negotiations were lost.

Traditional follow-up methods combining email, SMS, and phone calls were all designed assuming inside sales operation and could not handle automatic lead generation during nights and holidays. Additionally, in recent years, it has become difficult to connect by phone and obtain consent after connection, further exacerbating the problem of declining efficiency in phone-dependent follow-ups.

Deciding Factor for Implementation

Another background factor was the renewal of the private property viewing site, implemented in the fall of 2025. Previously, the mainstream flow was for inside sales to guide customers through properties after an application. However, receiving feedback such as "I thought I could view it immediately after applying" and experiencing sluggish application growth, they changed to a new experience design that allowed free viewing of properties for 30 days after application. Mr. Masuda reflects, "Many other services allow immediate viewing after application, and we felt disadvantaged when compared in terms of user experience."

The site renewal increased viewership, but a new challenge emerged: how to convert customers who view and then leave into business opportunities. The addition of a web engagement function, in addition to existing immedio utilization, emerged as a realistic solution to bridge the gap between "viewing" and "negotiation," leading to the decision to implement.

Results After Implementation

Since its introduction in November 2025, the number of leads converted into business opportunities via web engagement has reached approximately 40 cumulatively. This mechanism automatically handles a certain percentage of the approximately 200 monthly leads, functioning as a channel that can generate leads without the need for inside sales operation. Data showing that most applications concentrate on weekends and nights further supports this, and its evaluation within the company as a highly cost-effective measure is increasing.

Alongside increasing the number of leads, efforts were made to improve the "quality" of negotiations. Initially, due to ambiguous popup wording, mismatches occurred where customers considering entire buildings, which were not handled, flowed in. By explicitly changing the wording to "Tokyo Used Condominiums," mismatches were significantly reduced. Furthermore, a system of immediate calls by inside sales right after booking to confirm needs has been established.

NEXT immedio - Towards Sales Operations That Complete Lead Acquisition at Exhibition Venues

Going forward, they are considering embedding immedio not only in the current private property viewing site but also in LPs distributed to a house list of approximately 30,000 people monthly. While email newsletter open rates are around 20% and high-quality LPs are already created with varying themes each month, there is a challenge in converting views into actions. Mr. Oikawa expresses his vision: "Among those who visit the LP, those who spend a certain amount of time thoroughly viewing the page are highly likely to be considering its content. Displaying web engagement to such individuals should result in higher motivation."

By narrowing down highly interested prospective customers based on behavioral data such as dwell time and then engaging with them, they aim to achieve both improved call efficiency and expanded lead acquisition. Also, phone calls...
