Yahoo! Japan レビュー 

サイト自体が1995年からそのままのような見た目で、まったく変わっておらず、時代に全く適応していません。ごちゃごちゃしていて、無駄なものだらけです。
極めつけは、アカウント作成からたった1日で、理由もなくアカウントを停止されたことです。「乱用・不正利用に相当する行為が確認されたため」とのことですが、意味不明です。
こんな会社、早く潰れてほしい。

Yahoo ist absolute trash. They bombard me with spam mail and i can't unsubscribe because they want me to login first. I forgot my password and funny enough i don't get an email for resetting it. God awful. Let people unsubscribe from your bull crap without having to login.

Recently, I had one of the most frustrating and surreal experiences I have ever had with an online service. I had purchased tickets for an event through Yahoo Japan’s PassMarket system, using their recommended convenience store payment. The payment was completed, and the tickets appeared in my account.

Then, without any notice, warning, or explanation, Yahoo permanently suspended my account. I could no longer log in to retrieve the tickets I had legally purchased. When I contacted customer support, I received nothing but templated replies stating that my account was blocked due to “suspicious activity” and would never be restored.

What shocked me most was not only the lack of any specific reason, but the total absence of any human consideration. There was no appeal process. No one reviewed my case individually. No effort was made to confirm whether I was, in fact, a legitimate customer who had simply bought two tickets and paid properly.

This is not how a modern platform should treat users. Even companies often criticized for being “evil,” like Facebook or Google, have multiple warnings, structured appeals, and at least some level of accountability. With Yahoo Japan, it was simply: one vague accusation, instant irreversible lockout, and zero help in recovering my purchase.

Had I not decided to check my tickets days in advance, I would have shown up at the event with nothing—no proof, no recourse, no refund. This experience completely destroyed any trust I had in Yahoo Japan as a company.

Fortunately, the event organizers were kind and professional enough to verify my purchase manually and issue alternative confirmation. Their human approach stood in stark contrast to Yahoo’s automated contempt for customers.

This was the last time I will ever rely on any Yahoo Japan service. If you care about your data, your purchases, or your peace of mind, I strongly recommend you do the same.
