Kumamoto craft beer company goes bankrupt with debts of about ¥366 million

Diamond Brewing (Kumamoto), a company that brewed local craft beer and also ran a beer hall in Kumamoto Prefecture on Kyushu, in south-western Japan, was granted a bankruptcy commencement order by the Kumamoto District Court on 5 June 2026. According to the credit research firm Tokyo Shoko Research, its total liabilities came to about ¥366 million, owed to 138 creditors.

Even after raising capital more than fifty-fold

According to press reports, the company had increased its capital from ¥3 million at its founding to ¥156.78 million in the end. This suggests it was raising money from outside investors to expand the business, yet it still could not keep going. The latest reports do not explain in detail how it came to bankruptcy. A business that combines a brewery with a restaurant can become a gathering place for local people, but it also carries the burden of running two operations at once.

The appeal and fragility of “craft”

The Brewers Association, the American craft beer trade body, names being small and being independent of large alcohol companies as the conditions for a craft brewer. In Japan, the word “craft” is widely used to convey a handmade feel, rarity and the dedication of the maker. Being small gives a brewer character, but it also means thinner margins in sales and cash. The cause of this bankruptcy has not been made clear, but it is a reminder of how hard it is to run a small brewery. Many sake breweries in Japan are also small, and they may not be free of the same challenges.

For readers in Europe: look at the makers

When choosing Japanese craft beer or regional sake in Europe, look beyond the brand name and find out who makes it and where. Products from small makers are imported in small quantities, so you cannot count on finding the same one again next time. If you come across a bottle you like, it is worth asking the shop or importer how the maker is doing. Because the flavour of beer changes greatly with freshness, check the production date and best-before date, and choose bottles that have been stored refrigerated. One way to support small breweries is to learn about the makers and their products and to choose with conviction.
