However, it was not possible to reply to the attack email. When our association contacted the email address listed in the email to verify the facts, the email could not be delivered, and an \"Address not found\" error was returned by the receiving server.<\/p>\n\n\n\n In other words, while defamation-type emails were unilaterally sent to parties related to our union members, when our union attempted to check directly, the person alleged to be the sender was unreachable.<\/p>\n\n\n\n The delivery failure notice confirmed by our association displayed the following message:<\/p>\n\n\n\n Address not found Furthermore, the following wording has also been confirmed in the response from the remote server:<\/p>\n\n\n\n This user doesn\u2019t have a yahoo.co.jp account.<\/p>\n\n\n\n Did the email address not exist from the beginning? At this time, our union does not assert either of them. However, regardless of which possibility it may be, the core of the issue remains unchanged.<\/p>\n\n\n\n A person sent an email to associates of our union members containing content that negatively impacts contractual and business relationships, while keeping their own contact information unverifiable. This is neither a normal inquiry nor a public-interest whistleblowing activity. It is an act aimed solely at damaging the reputation of others while keeping accountability ambiguous.<\/p>\n\n\n\n Our union considers such methods to be extremely malicious and cowardly.<\/p>\n\n\n\n What our association views as the most problematic is not the fact itself that the email address was undeliverable.<\/p>\n\n\n\n What is truly serious is how a person who cannot even be identified by their reply address was able to obtain the contact information of our union members' associates and deliberately send emails targeting them.<\/p>\n\n\n\n That email was not merely a comment on one of our association\u2019s published articles.<\/p>\n\n\n\n The content of the message was intended to urge our union members' associates to review their contractual and business relationships based on a specific relationship. In other words, it is possible that the sender had, at least in some form, acquired information regarding our union members' associates.<\/p>\n\n\n\n Then where did that information come from?<\/p>\n\n\n\n Is it actually from Mr. Nakano Tsunayoshi himself? Or did Last One Mile Co., or individuals related to or surrounding the company, obtain information regarding our union members' associates and involve themselves in attacks using third-party names?<\/p>\n\n\n\n At this time, our union does not conclude the involvement of any specific individual or corporation.<\/p>\n\n\n\n However, there is no reason to exclude it from the scope of the review.<\/p>\n\n\n\n This is because this email was not sent directly to our union, but was sent to parties outside our membership\u2014that is, to our business partners.<\/p>\n\n\n\n This is not a statement issued by our union itself, but rather an attack aimed at our members\u2019 social credibility and livelihoods.<\/p>\n\n\n\n Regarding Mr. Tamaki Nakano, it has been reported that the Kagoshima District Public Prosecutors Office prosecuted the Kagoshima-based consulting firm Global HR Technology and its representative, Defendant Tamaki Nakano, for violations of the Consumption Tax Act and other offenses, and subsequently re-arrested him on suspicion of subsidy fraud and other charges.<\/p>\n\n\n Our union is neither an investigative nor a judicial body regarding these criminal cases. Therefore, we are not in a position to make final judgments on individual illegality or criminal liability.<\/p>\n\n\n\n However, there is one characteristic to the problems surrounding Mr. Nakano that our union has been aware of up until now.<\/p>\n\n\n\n The repeated concern that has surfaced is that actual records, communications, devices, relationships, and flows of money are being obscured\u2014after becoming problematic\u2014through damage, deletion, shifting of blame, substitution of names, and other methods.<\/p>\n\n\n\n This email under the name of \"Kenichi Tanaka\" is also very similar in structure.<\/p>\n\n\n\n Our union views this matter as extremely serious.<\/p>\n\n\n\n Regarding this matter, our union is naturally considering the possibility of attacks by Mr. Nakano's relatives, associates, and collaborators. Our union is taking another possibility very seriously.<\/p>\n\n\n\n That is the possibility that this email is a new move of domination intervention and union attack against our union by Last One Mile Co. or related parties around them.<\/p>\n\n\n\n We recognize that Last One Mile Co. and its affiliates have long and continuously subjected our union and its members to coercive and intimidating domination and intervention.<\/p>\n\n\n![\"\"](\"https:\/\/minnanounion.info\/wp-content\/uploads\/2026\/07\/\u30e1\u30fc\u30eb\u4e0d\u901a-1024x336.png\")
<\/figure>\n\n\n\nDominant intervention by a person with no return address<\/h2>\n\n\n\n
Your message wasn\u2019t delivered because the address couldn\u2019t be found, or is unable to receive mail.<\/p>\n\n\n\n
Was it deleted after being sent?
Is it just a typo?
Did a third party use someone else's name?<\/p>\n\n\n\nThe issue is not the email address. It is the information acquisition channel.<\/h2>\n\n\n\n
Is it from Mr. Nakano's relatives, associates, or collaborators?
Did individuals close to Mr. Nakano use affiliated party information to counter our union's messaging?<\/p>\n\n\n\nSimilarity to the pattern of \"erasing what once existed\" surrounding Mr. Nakano<\/h2>\n\n\n\n

But that's not all.<\/p>\n\n\n\n
