A Silicon Valley entrepreneur who was accused of sexual harrassment online claims that his supposed female victim is in fact a male business rival.

Earlier this month Anis Uzzaman, CEO of San Jose-based Fenox Venture Capital, launched a lawsuit against the anonymous Japanese blogger who accused him.

But now Uzzaman has amended his complaint, saying that she is in fact Brandon Katayama Hill, the founder and CEO of San Francisco-based consulting business btrax.

The suit, initially filed in in San Mateo County Superior Court on June 5, said Uzzaman had been defamed by an unnamed woman on Japanese blogging site Hatena on March 11.

Uzzaman, who is fluent in Japanese and specializes in Japanese and South-East Asian investments, included English translations of the posts in his suit.

'I got sexually taken advantage of by a very famous Silicon Valley VC,' the blog said, according to the original suit.

'It was not that I was in a relationship with him, I was just pushed around and taken advantage of.'

Allegations: According to the suit, the article accused Uzzaman of taking advantage of 'very many cute girls' and identified him as a VC with 'dark skin' and 'sharp eyes'

It claims that he took her to dinner then 'pushed' her to go back to his five-star hotel room with promises of funding for her company.

'If you come with me, then you can operate in the global level,' the Hatena article quotes him as saying. 'You are going to lose the biggest opportunity if you do not come.'

The post doesn't say what is supposed to have happened after that, but does claim that he told her to stop calling her after that evening.

The initial court filing said that while the blogger didn't name Uzzaman, there were enough details that commenters on the post were able to identify him.

According to the suit, the article describes him as being 'not a Japanese' but a fluent speaker of the language, and 'a very famous VC, flying around the world,' and describes his 'dark skin color and sharp eyes.'

It also makes a number of other allegations against him, including how 'He says that he does things for Japan, but in reality, he does it for money, power, and women,' the suit claims.

The article also described how 'a lot of people from Japan, including students, and many very cute girls, come to him, and he takes advantage of them,' the suit said.

It also claimed that there are 'many other victims who fall into his trap' and that women in his company 'are taken advantage of' but don't speak up because of visa issues.

Rivals? Uzzaman's Fenox Venture Capital is a rival to Hill's btrax, he claims in a suit against Hill. He says he unmasked the deception when the IP on the blog was traced to Hill

Last week's updated filing includes a letter from Hatena, provided after Uzzman petitioned them through a Tokyo court, saying the post had been made from a San Mateo County IP address.

It includes another document from Comcast, which was subopenaed to provide details of the user, claiming that the IP is that of Brandon Hill, and giving a service address in Westmont Drive, a suburb of Daly City located south of San Francisco.

The court documents claim that both Fenox and btrax 'operate business in the same general domain, working with startup companies that are funded largely by Japanese corporations.

'While Plaintiffs obtain infestment funds from Japanese large corporations for investment in startup companies globally, Defendant Brandon Hill performs consulting services for those Japanese large corporations to give them access to the Silicon Valley ecosystem.'

The documents say that Hill was born and raised in Japan, is known for blogging on Hatena, and has a history of badmouthing Uzzaman and Fenox.

Denial: Hill denied Uzzman's (pictured) claims, saying that he does not consider them competitors and that more than 50 people could have used his WiFi to publish the article

It also claims that Uzzaman's company, Fenox, upstaged btrax last year by creating Startup World Cup, a competition that competed with btrax's Japan Night event.

The suit demands unspecified damages based on past and future lost earnings from the claims, and damage to Uzzaman's reputation. It also asks for unspecified punitive damages.

In an email to DailyMail.com, Hill denied all claims made against him.

He said: 'Regarding the allegation, we consider it as false allegation for the following reasons.

'Though it could be through the IP which I own, I am not the person who wrote or published the article.

'We do not complete [sic] their business, btrax is a design company while Fenox is a VC, invests in startups. Thus there is no business conflicts whatsoever.'

He also denied that Fenox's Startup World Cup in any way competed with his own Japan Night.

'We stopped organizing our event, Japan Night in 2015,' he said. 'The event itself is not profit-making business model in the first place. But we organize it to help Japanese startups companies go global.

'As a matter of fact, there was a case Fenox sponsored Japan Night back in 2014. In that we regards, we and Fenox share the same vision to help startups, and we support Startup World Cup by a few of us attending the event.

'I (we) have no reasons to damage their business. Earlier this month, we have notified Fenox that there is a possibility that my IP was used to published the article by someone as there are over 50 people who know the ID/PW [ID and password] of the WiFi.

'Currently we are communicating with Fenox via our attorneys.'

He added that he has 'never spoken negatively about Mr Uzzaman,' saying that 'I admire him and we've known [each other] over five years. I do not have any negative feeling towards him.'

And he said that he has 'never written any articles on Hatena in my lifetime.'

When contacted by DailyMail.com about Hill's remarks, Katrina Saleen, the lawyer representing Uzzaman and Fenox, said her clients had no choice.

'My clients had to stand up and protect their honor, find out who is behind these false accusations, and send a message to the blogger and the community that this is shameful,' she said.

'People cannot be allowed to hide behind anonymity and ruin reputations over false allegations.'

In a statement to Mercury News, she also noted that the claims came after increasing media coverage of sexual harassment in Silicon Valley.

Those previous cases have included Travis Kalanick being ousted as Uber CEO after ex-employee Susan Fowler Rigetti accused the company of having a toxic culture towards women.

'While I have seen a rise in awareness regarding sexual harassment in Silicon Valley in recent years, I have also seen a steep increase in anonymous online defamation,' Saleen said.

'We need to be careful to hold wrongdoers accountable, but not to blindly believe everything we read online.'
