BEER BULK J (10ants brewing) is a beer pub in the Seiseki-Sakuragaoka area of Tama City, Tokyo. It specializes in draft beer poured by weight, while also offering bottled and canned beer for both on-site drinking and takeaway.

In its July 6 Instagram post, the shop announced hours from 16:00 to 24:00 and told followers to check the image for the day’s tap list. The lineup visible there includes `THE Fourth Dimension Blue label` and `BONE BONE` from 10ants Brewing, `府中Sweet Potato Stout` and `Belgian White Ale` from GLaSS Hopper Brew Team, `Blanche du Paradis` from `Dieu Du Ciel!`, and `NEW WORLD IS YOURS` from `Derailleur Brew Works`. The selection spans IPA character, stout, Belgian-style wheat and white beer, and a grapefruit-led hazy lager, giving the bar a broad but coherent range.

The post also previews `Craft Beer Fes in Tokyo Tama Mirai Messe 2026 Summer`, scheduled for July 10-12 in Hachioji. BEER BULK J plans to join with beer and food, and the shop will be closed during those event days. It is a good snapshot of how the bar balances its daily taproom role with event appearances across the Tama beer scene.
