Kino and X-mobile Push Joint Stake in Taiyo Bussan to 32.4%

Masanori Kino, an individual investor, and X-mobile Inc., the telecommunications company where Kino serves as representative director, now jointly hold 32.41% of Taiyo Bussan Co., Ltd. (9941), a company listed on the Tokyo Stock Exchange. That is up from 17.17% before July 1, 2026, according to an amendment to their large-shareholding report filed with Japan's Financial Services Agency on July 8.

The jump came from a single event: a share exchange completed on July 1 that added 86,567 shares to Kino's holding and a combined 350,205 shares to X-mobile's, 220,354 of them acquired directly and 129,851 through X-mobile Sky Fund No. 2. Kino now holds 436,567 shares, 17.98% of the 2,427,848 shares outstanding. X-mobile holds 350,205 shares, or 14.42%. Their combined 786,772 shares, 32.41% of the company, triggered a mandatory filing under Japan's large-shareholding rules, which require disclosure whenever a joint holding moves by one percentage point or more.

Before the share exchange, the pair had already been building a position. Filing records show at least 17 separate purchases between May 7 and June 30, including two larger off-market trades, 111,200 shares on May 7 at ¥1,084 apiece and 10,500 shares on June 12 at ¥1,216 apiece, alongside a series of on-market purchases ranging from 1,000 to 11,500 shares at a time. Kino reported using ¥437.3mn of his own funds to finance the purchases covered by this report.

The stated purpose of the holding is "pure investment and making significant proposals," language Kino and X-mobile used when filing under Japan's large-shareholding disclosure rules. Shares acquired in the July 1 exchange carry a catch: for six months, until early January 2027, neither filer can sell, transfer, pledge, or otherwise dispose of them without Taiyo Bussan's written consent, giving the company a window before the enlarged stake becomes freely tradable.
