Japan AI voice-cloning scam impersonates company presidents, with reported losses reaching JPY 4.5 billion

Japan’s ITmedia Enterprise reported on Sept. 3 that a voice-cloning scam using artificial intelligence is already being used against companies, citing a former Tokyo Metropolitan Police Department official. In the scheme, fraudsters clone a company president’s voice, call the accounting staff directly, and demand an urgent bank transfer. The report cited losses of JPY 4.5 billion, but did not say whether that figure referred to a single case or a cumulative total, nor did it specify the time period covered. The script described in the report is simple but effective: the caller tells accounting personnel to transfer JPY 10 million to a client on the same day and frames the payment as a confidential M&A matter that must not be discussed with anyone else. According to the report, these scams tend to work when three elements appear together: the caller ID shows the executive’s real mobile number, the voice sounds like the executive, and the caller keeps stressing urgency. ITmedia Enterprise also said only tens of seconds of audio may be enough to produce a usable cloned voice, with samples often available from earnings calls, recruiting videos, conference recordings, and YouTube.

Metaplanet stock option pool dispute draws renewed shareholder backlash

Shareholder criticism over Metaplanet’s 10th executive stock option pool is continuing, with objections centered on dilution and governance transparency. The Japan-listed bitcoin treasury company originally structured the pool at 20% of fully diluted share capital, with the size set to expand automatically as the company issued new shares to acquire more bitcoin. Some shareholders have called for the cancellation of 273 million additional shares created through the change and asked the company to provide clearer disclosure around future decisions. On Aug. 18, Metaplanet froze the option pool at 319.5 million shares, but critics said the move locked in heavier dilution because the pool had already expanded from 46 million shares to 319.5 million. CEO Simon Gerovich said he would revisit governance and compensation policies and clarified that he is only a significant non-controlling shareholder in MMXX Ventures’ parent company, not an executive. On Aug. 31, the company disclosed that Gerovich had exercised 92,000 shares from the pool.

Citi to launch tokenized deposit cross-border transfer service for Japanese firms by year-end

Citi will roll out an international transfer service for Japanese corporate clients by the end of the year, according to CoinDesk. The offering will use tokenized deposits and enable instant cross-border payments on a 24/7 basis across five countries. CoinDesk said the move would make Citi the first foreign bank to provide this type of service in Japan. The report ties the launch specifically to Japanese businesses and frames the product as a cross-border payments service rather than a broader consumer banking rollout. No additional details on the five countries or the service structure were disclosed in the brief.

Japanese writer tests Pangram: Gemini-written Japanese text flagged 100% AI, 2015 manuscript labeled 100% human

A test by Japanese Business author Masakazu Kobayashi put AI writing detector Pangram through a simple Japanese-language trial and got sharply split results. One sample, a Japanese article generated by the free version of Google Gemini, was labeled 100% AI-generated. The other, an afterword manuscript Kobayashi wrote for his 2015 book "AIの衝撃 人工知能は人類の敵か," was labeled 100% human-written. The report does not claim this proves Pangram works on Japanese with the same 99.99% accuracy the company has advertised elsewhere. It explicitly says two samples are far too few for that. Still, the test suggests Pangram, which is mainly offered as an English-language service, can process and identify Japanese AI text as well. The article also points to a larger issue around AI detectors. Pangram has said it looks for "many weak signals" associated with AI-generated writing, but it has not disclosed much technical detail. That leaves the core problem of explainability unresolved. The report further notes that the real debate is shifting away from a binary question of whether a text is AI-written and toward how much of a document was produced or reshaped by AI, especially in paid publishing environments such as Substack.

Japan’s FX Reserves Fall Below $1 Trillion as Treasury Selling Suspected in Record Yen Intervention

Japan’s foreign exchange reserves fell below the $1 trillion mark at the end of August after a sharp drop in foreign securities holdings fueled speculation that Tokyo sold U.S. Treasuries and other overseas assets to fund record-breaking yen intervention. Data released by Japan’s Ministry of Finance showed foreign securities holdings declined by $87.8 billion from a month earlier, closely matching the scale of the intervention. The ministry had already confirmed that authorities spent about ¥15.4 trillion, or roughly $98.6 billion, in the month through Aug. 26 to support the yen, marking the largest monthly intervention on record, with part of the operation carried out jointly with the United States. Japan’s total FX reserves fell by $94.6 billion to $995 billion. The data did not disclose the makeup or maturity profile of the securities sold, but market participants estimate that roughly 70% of Japan’s reserves are invested in U.S. Treasuries. Finance Minister Satsuki Katayama also said future intervention could use the Federal Reserve’s FIMA Repo Facility, which would give Japan access to as much as $60 billion in daily liquidity without requiring outright Treasury sales.
