BREAD THAT TOOK ITS TIME. DID YOU?

Hulk CoreVault is an artisan bakery in Kanazawa, Japan. We bake in small batches every morning (and we mean small. Sometimes we sell out by 10 a.m., so you have been warned). Everything starts with a long cold ferment and ends with you eating it over the sink because you could not wait.

BREAD & PASTRIES

This is what we bake. Not everything is available every day. The seasonal items rotate with what is actually in season, and some loaves are limited to a small number per bake. If you have your heart set on something specific, pre-order the evening before. We bake Tuesday through Sunday, doors open at 8 a.m.
01

COUNTRY MICHE

Our flagship loaf. Made with 80% Hokuriku wheat flour from our Toyama mill and 20% whole rye, fermented cold for 20 hours, then baked directly on the deck stone. The crust is thick and crackles when you cut it. The crumb is open and slightly tangy. This is the one restaurants order.

¥1,200
02

SESAME RYE

A denser, darker loaf made with 40% dark rye flour and a generous coating of toasted white sesame on the crust. The dough is mixed with a small amount of molasses, which gives it a faint sweetness that works well with strong cheese or miso butter. Baked in a pullman tin, sliced to order.

¥980
03

AUTUMN CHESTNUT BUN

A seasonal enriched roll filled with a paste made from Ishikawa-grown kuri chestnuts, a little brown sugar, and a pinch of cinnamon. The dough is brioche-style, enriched with local eggs and butter. Available through October and November only, while the chestnuts last.

¥420
04

PLAIN CROISSANT

Laminated with Hokkaido butter, folded 27 times over two days. We do not add vanilla or sugar to the dough. The butter is the flavour. Baked until the layers are genuinely crisp, not just golden. Best eaten within two hours of purchase.

¥480
05

SOURDOUGH FOCACCIA (HALF SHEET)

Baked on Fridays and Saturdays only. The dough is the same as our country miche base, pressed into an oiled tray, dimpled, and topped with whatever is good that week. Sometimes rosemary and flaky salt, sometimes roasted tomato and shiso from our garden. Ask at the counter for the current topping.

¥680
06

STARTER KIT

A small jar of our sourdough starter (enough to begin baking immediately), a printed feeding schedule, and a card with our basic country loaf recipe. We sell these on Saturdays only. The starter is ten years old and has a mild, yogurt-like sourness.

Autumn baking in Kanazawa: working with local chestnuts

Chestnuts in Ishikawa Prefecture start coming in from late September, and the season runs through November. The kuri grown in the hills around Kanazawa are known for their size and sweetness, and they are genuinely different from the smaller, drier chestnuts you sometimes find at supermarkets. Working with fresh chestnuts is more labour-intensive than using a commercial paste, but the flavour difference is significant enough that we have never seriously considered switching.

Here is where to start

Based on your answers, the Country Miche or Sesame Rye is likely your best match for savoury pairings, while the Chestnut Bun or Croissant suits sweeter mornings. If you are new to sourdough, the Starter Kit on Saturdays is a good way in. Check what we are baking this week or pre-order the evening before.

Maker

Sakura Ueda

Founder, Established since 2018

Sakura Ueda spent six years working the morning shift at a wholesale bread facility in Kanazawa before deciding that 4,000 identical loaves a day was not the life she had signed up for. She trained under a retired French-style baker in Kyoto for two years, learning to read dough by feel rather than by timer, then opened Hulk CoreVault in 2018 with one deck oven, a secondhand spiral mixer, and a sourdough starter she has kept alive since 2016. Outside the bakery, she grows shiso and myoga in a small plot behind the building, reads crime novels in the bath, and is mildly obsessed with the bread scenes in old Studio Ghibli films.
