In-house listing site that bypasses SUUMO/HOME'S 反響単価 — broker pays ¥49,800/mo flat, keeps 100% of 仲介手数料
受注インパクトJP brokers report ¥250k-¥500k+ ad spend per closed contract on SUUMO; mid-size firms burn ¥10M/yr on portal ads (80% of marketing budget). At ¥49,800/mo (KGA price), break-even is <1 contract — every additional close is pure margin recovered. This is THE pitch for SMB brokers
開発工数Medium — Next.js listing template + faceted search (Algolia/Typesense) + 内見予約 calendar; reuse Komoju for application fee or guarantor fee collection

初期費用 simulator embedded on every listing card with editable 敷金/礼金/保証会社 sliders + auto-total in yen
受注インパクト礼金 sticker-shock and opaque 初期費用 are the #1 and #2 friction points (Yahoo知恵袋 + YOLO Japan 47% data). Showing 'this 西荻窪 1K ¥85,000/mo costs ¥425,000 to move in, breakdown below' on the listing kills bounces and pre-qualifies leads → fewer wasted 内見s
開発工数Low — 13 inputs, deterministic formula; can be a stateless React component reused across listings
3
360° VR 内見 + LINE chat inquiry (no phone, no relative-in-Japan demand, no agent calling landlord behind your back)
受注インパクトEliminates the two failure modes that cost SMB brokers their best foreign + younger-Japanese leads: pushy 営業電話 fatigue and the late-stage phone-veto by landlord/guarantor. Brokers who adopted VR内見 report 90% vacancy reduction (Spacely case studies)
開発工数Medium — Spacely/Theta 360 embed is plug-and-play; LINE Login + reservation flow needs LINE Messaging API + a calendar (Cal.com/custom)
