NTT Docomoの収益モデルについて、RCR Wireless News公式の報道記事（https://www.rcrwireless.com/20200929/5g/ntt-plans-to-turn-ntt-docomo-into-wholly-owned-unit-via-tender-report）で確認できます。Existing references describe docomo as an NTT Group brand with Japan's largest subscriber base, contrasted with au/KDDI, but say nothing about the 2020 delisting/buyout transaction, so there is no overlap.具体的には「NTT expects to turn listed mobile carrier NTT DoCoMo into a wholly owned subsidiary via a tender offer, nearly JPY4 trillion ($37.9 billion). NTT, which currently owns 66.2% of NTT DoCoMo, is considering making a tender offer to acquire the remaining shares and delist the company. This deal will make DoCoMo stronger...generate greater synergies within the group and reallocate resources so that it can better compete with overseas rivals in areas such as 5G and IoT.」といった記載が確認できます。限界として、収益区分・課金体系は決算期や製品改定により変わりうるため、この内容は開示時点のものです。 The figure (nearly JPY4 trillion / $37.9 billion) reflects the initially reported deal size; the article does not confirm the final closing terms as later formalized.Current Statusとして、2026年08月27日に当該Sourceを取得し、上記の内容を確認しました。Source種別としては、これは第三者であるRCR Wireless Newsによる報道であり、企業の自己申告とは性質が異なりますが、報道時点の取材内容に基づくものです。
