Suzuken (JP3398000004) is scheduled to resume production at its Kumamoto plant on October 19, 2026, a development reported by Moomoo on October 16, 2026. The restart gives investors a concrete operational marker before the company's next results date.

What does the restart mean?

The Kumamoto facility is operated by Suzuken unit Sanwa Kagaku Kenkyusho. The production resumption follows an interruption linked to the 2026 Kumamoto earthquake, and the October 19 date places the event immediately before the next reporting milestone.

Financial context points to moderate growth with uneven profitability. GoAI Digital reported fiscal 2026 revenue of JPY 2.49 trillion, up 3.61 percent from fiscal 2025, while operating income fell 2.02 percent to JPY 36.38 billion and net income rose 10.55 percent to JPY 38.14 billion. For investors, the plant restart matters because it adds an operational checkpoint to a year in which revenue expanded faster than operating income.

Buyback timeline reaches 990,000 shares

On August 28, 2026, Japan IR reported that Suzuken had authorized a buyback capped at 4,000,000 shares and JPY 18.00 billion. From September 1 through September 30, 2026, the company acquired 990,000 shares for JPY 5.13 billion, according to the same October 1 disclosure.

On October 16, 2026, the production restart was the latest dated operational event, with the October 19 resumption date as its central figure. The sequence links capital allocation, plant continuity and the upcoming financial update without relying on a peer-ratio comparison.

When are the next key dates?

The Kumamoto production resumption is scheduled for October 19, 2026. Suzuken's next results are scheduled for November 12, 2026, according to Shikiho Online. That report should provide the next dated test of revenue, operating income and the effect of the production interruption.

Stock context before the results

Suzuken's market capitalization stood at JPY 357.9 billion on October 16, 2026. The combination of a JPY 5.13 billion September buyback, a scheduled October 19 plant restart and November 12 results gives the stock three company-specific reference points for the next phase of trading.
