Mitsui Matsushima (Cap: ¥146B) on 7/22/26 announced:

1. a modest upward revision to FY3/27 guidance,

2. a dividend hike from ¥76 to ¥130 (+76%), and

3 the acquisition of Sanyo Co.

Items (2) and (3) largely explain the sharp share-price move. I highlighted Mitsui M on 4/13/26 (note available to paid subscribers) when few analysts were paying attention to this “ultra‑mini SoftBank.” Shares have since appreciated ~70%.

The company has exited its volatile, SDG‑misaligned coal business and now focuses on small/mid‑sized M&A across industrials, services, and adjacent sectors—targeting niche, stable, easy‑to‑understand businesses.

Sanyo fits this profile. It is a leading domestic cotton‑swab manufacturer with 50+ years of technology and quality control, top share in general‑use swabs, and a growing global footprint, including supplying the largest U.S. distributor. It also operates in higher value‑added industrial and medical segments; its HUBY brand is used in semiconductor, electronics, and optical‑component production where ultra‑low fiber shedding is essential.

My original thesis was Mitsui M’s ability to locate and consolidate growth businesses. The Sanyo acquisition validates that thesis, and the market responded with a ~45% rally over two days.

Guiance Drivers:

Special gain from listed‑stock investments at MM Investments

Incremental FY3/27 revenue from Sanyo

Adoption of a progressive dividend policy, with ¥130 as the new baseline

Valuation:

When first highlighted, shares traded below 1x P/B and ~13–14x P/E. They now trade around 1.5x P/B and 20x P/E. After the sharp rerating, some profit‑taking is possible on 8/7 when Q1 FY3/27 results are released.
