Prior to 2009, Japan Post was not connected to the Japanese Bankers Association (Zenginkyo) payment processing network, making it impossible to wire money directly between Japan Post and most other Japanese banks.
Før 2009 var Japan Post ikke forbundet til den japanske bankorganisations (Zenginkyo) betalingsnetværk, dermed var det ikke muligt at overføre penge direkte mellem Japan Post og de fleste andre japanske banker.
