Japanet Withdraws Twinbird Bid After Opposition

Japanet Holdings withdrew its tender offer for home appliance manufacturer Twinbird on September 2, 2026.

Meanwhile, Yomiuri Shimbun highlighted the strategic rationale behind Itochu's ¥200 billion+ bid for Dentsu Soken, noting Itochu's intent to strengthen its digital business capabilities through this consolidation with the Dentsu Group subsidiary.
