Portals own the broad searches in Japanese and your agency is invisible
"東京 マンション 購入" (Tokyo apartment purchase) or "渋谷 不動産" (Shibuya real estate) — portals own these searches entirely. Your agency's domain does not appear. But "[ward] 不動産会社" (real estate company [ward]) and specific area searches are winnable for an agency with the right location content. Most never build it.
