This highly polite greeting expresses gratitude for ongoing support or a good working relationship. It's common in business when contacting clients or partners you've worked with before, acknowledging their continued contributions. Example: "いつもお世話になっております、ABC会社の田中です。" (This is Tanaka from ABC Co., thank you for your continued support.)

日頃の感謝や継続的な関係に使う丁寧な挨拶。ビジネスで取引先や顧客によく使います。例：「いつもお世話になっております。」
