For years, Simon Yeung, real name Siming Yang, moved through Tokyo like a shadow: quietly, discreetly, and always just out of reach. He was never a public figure, never loud, never attention-seeking. His greatest talent was staying hidden. But now, he’s taken that instinct to a new and unnerving level. Simon hasn’t just gone quiet — he has disappeared entirely. And the last time anyone saw him was in a place so public, so mundane, and so deceptively innocent that it almost feels planned: sitting beside Keigo Miura at a baseball game in Tokyo.
It was an odd sight in retrospect — a man infamous for operating in secrecy suddenly appearing in the open with Keigo, a known drug user and habitual liar whose own life is collapsing under the weight of scandal. They watched the game, chatted casually, and then Simon slipped back into the world. Except this time, he didn’t resurface. No nightlife. No travel. No sightings. No digital footprint. Nothing but a void where a man with a very dark history used to be.
Simon’s disappearance would barely register if he were just a private citizen. But Simon wasn’t private; he was dangerous, hiding behind privacy to conceal a long, rotten trail of predatory behavior and criminal activity. Witnesses have reported him offering women money for sex the moment he met them. Eric Chang himself reported that Simon raped a Hong Kong prostitute with a beer bottle and had to pay around $15,000 USD to her mafia handlers to avoid violent retaliation. On another occasion, Simon stayed overnight in a hotel room with Hyeji Bae and Yui Miura at Universal Studios Japan. While Yui was on the phone with her husband (Kiego Miura), Simon told her to remove her underwear — and Yui tried to excuse it by claiming her husband “allows” her to stay overnight with other men. When confronted later, Simon simply ignored all communication, slipping back into the safety of silence.
His crimes weren’t limited to sexual misconduct. Simon was also tangled in major insider trading cases, with SEC documents showing he pocketed millions of dollars in illegal profits. His financial crimes alone would be enough to make any man flee, especially as the network around him began to unravel. Every single one of Simon’s closest associates — Yui, Hyeji, Keigo, Silverstar Oh, Victor Chang, Eric Chang — is now under scrutiny or drowning in scandal. Their secrets are pouring out. Their lies are collapsing. Their criminal histories are catching up to them. Men like Simon don’t wait around when their world starts burning. They run. And Simon’s disappearance feels like the ultimate escape plan.
Yet something about his vanishing act is different. It isn’t gradual or subtle. It is absolute. One day he’s sitting at a baseball stadium beside a known fraud, and the next day he’s gone as if swallowed by the city. People within the circle claim they haven’t heard from him. Places he used to frequent haven’t seen him. Even the digital traces he occasionally left have gone silent. For a man who has built a life through secrecy, this level of disappearance looks less like personal choice and more like a controlled extraction — whether by his own hand or someone else’s.
There is now a $1,000 USD (155,500 JPY) reward for any credible information regarding Simon’s whereabouts: photos, messages, eyewitness accounts, anything that can confirm where he went or who might be harboring him. Someone knows what happened. Men like Simon don’t just dissolve into the air. They hide with purpose, with strategy, with fear — or under pressure.
His last public sighting with Keigo is the key. That was the moment he surfaced, however briefly, before slipping back into the shadows. And for a man with his history — sexual misconduct, violence, financial fraud, and a lifetime of exploiting women — disappearing isn’t a coincidence. It’s a warning.
Simon Yeung was always private, always calculating, always hiding. But this silence is different. This is the silence of a predator who knows it’s only a matter of time before the past catches up to him. And if he believes he can disappear forever, he’s wrong. People are looking for him now. His victims are demanding answers. And the clock is ticking on how long he can stay hidden.
Wherever he is, whatever he’s running from, one thing is certain:
The hunt for Simon Yeung has begun.
