The story behind Cedar Vaultline

Small-batch granola, made slowly in Japan

Haruki Nishimura spent seven years as a pastry chef at a hotel in Yokohama before he started making granola on a Sunday afternoon in 2017. He had been dissatisfied with every commercial granola he could find in Japan: too sweet, too uniform, baked at temperatures that drove off the oils before they could do anything interesting. He bought a second-hand convection oven from a retiring baker in Zushi, carried it up three flights of stairs, and spent the next four months testing ratios of oats, kokuto, and sesame oil until the apartment smelled the way he wanted it to smell.

The name Cedar Vaultline came from a notebook sketch Haruki made in the winter of 2017. He was thinking about the way a cedar barrel holds whisky. The wood breathing slowly, the contents changing over months. He wanted the brand to carry that same sense of patient transformation. The first proper batch sold out at a Setagaya farmers market in March 2018. He had made 30 bags. By June of that year he had moved production into a licensed food-preparation kitchen in Ofuna and hired one part-time assistant. The current team is three people, and the kitchen is still in Ofuna.

Our story

Today Cedar Vaultline ships to customers across Japan and to a small number of wholesale accounts in Tokyo, Kyoto, and Sapporo. The range has grown from two blends to seven, with one or two limited seasonal roasts each year. Haruki still does the final quality check on every batch himself, tasting from a small ceramic bowl he bought at a Setagaya pottery stall in 2018. The bowl has a chip on the rim now. He has no plans to replace it.

How we do things differently

Single-oven roasting

Every batch goes through one convection oven at 155°C for exactly 28 minutes. No conveyor belts, no industrial dryers. The colour you see in the bag is the colour it came out of that oven.

Oats from Hokkaido

We source rolled oats from Tanaka Grain Farm in Bibai, Hokkaido. The farm has been growing oats on the same volcanic-soil plots since 1971, and we have bought from them every season since 2019.

No refined sugar

We sweeten with raw Okinawan kokuto (black sugar) and cold-pressed sesame oil from a small press in Kyoto. The result is a low-glycaemic roast that does not spike and crash.

I still taste every batch from the same chipped bowl I bought in 2018.

What people say

I have been ordering the Original Sesame every month since 2021. It is the only granola I have found in Japan that does not taste like it was made in a factory.

Keiko M. · Monthly subscriber, Tokyo

We put the Hojicha and Walnut on our breakfast menu in April and guests ask about it almost every morning. Haruki was very patient explaining the sourcing when we first reached out.

Which blend fits your mornings?

Answer three questions and we will point you toward the blend that suits how you actually eat breakfast.

01 / 03
  1. How do you usually eat granola?
  2. What flavour direction appeals to you most?
  3. Do you have any ingredients you prefer to avoid?

Here is where to start

Based on your answers, the Original Sesame or Yuzu and Coconut blends are likely the best starting point. Both are available in 250 g bags so you can try before committing to a subscription. See the current range for full ingredient lists.

Haruki Nishimura

Haruki Nishimura trained as a pastry chef at the Yokohama Grand Pacific Hotel, where he spent seven years working the breakfast and patisserie sections. In 2017 he began experimenting with granola in his Setagaya apartment, driven by a specific frustration: every commercial granola he tasted was over-sweetened and under-roasted. He founded Cedar Vaultline in 2018 after selling out 30 bags at a local farmers market. Outside the kitchen, he collects mid-century Japanese ceramics and walks the Miura Peninsula coast most Sunday mornings before the oven goes on.
