Natto master (Birth of NYrture New York Natto. Part III)

A student must seek out the best teacher possible.

On the hottest day of the 2014 summer, I went to visit the oldest natto business in the city of Tokyo.  There, I was to meet Hiromitsu Amano, a fifth generation natto maker to learn about his methods.

Amanoya is located down the street from the famous Kanda Myojin Shinto shrine in the busy Akibahara/Ochanomizu area of central Tokyo.

The Amano family has owned and operated Amanoya, which produces premium natto as well as a number of other traditional Japanese fermented foods (amazake, koji and miso) since 1846. The small corner shop in front sells all the specialty foods they make; behind and underneath it are the facilities where they are created. The building and its underground fermentation rooms (similar to cheese aging caves) have been designated an official historic preservation site by the local ward government.

The Amanoya production facility includes specialized underground fermentation rooms over a century old.

Amanoya is the oldest natto producer still operating in metropolitan Tokyo. His family's Amanoya natto is a top-tier small batch product, available only in Tokyo in their own Amanoya shop and in a few local gourmet retailers and restaurants. In the 170 years since the Amano family began making natto, the basic technique has remained largely unchanged. Though technical advances have improved equipment, his natto is still made by methods passed down through generations and packaged by hand.

Hiromitsu Amano kindly invited me into his home to learn about his family's work producing natto and many other traditional fermented foods.

"Selecting the best available soybeans is key to making the best natto." shared Amano-san.  He said he sources his soybeans from the northern island of Hokkaido, where cooler temperatures produce high quality beans--sweeter and larger than most native Japanese soy varieties. From year to year he may buy from different farms, always looking for the best crop of that season.

Amano-san shared his knowledge and brought us inside his natto workshop to see how his natto is created.  There, I saw the simple set-up where he was able to produce such wonderful food, and I was inspired. He explained his natto-making process as his sons worked around us. But finally he said, "There is no great secret; the difficult part [of making natto] is in the simple doing with consistency and care". How modest, yet true of so many things.

Amanoya includes a beautiful little cafe where we sampled some fantastic amazake, a traditional fermented rice drink.

Much gratitude to Amano-san and his family for their kindness and generosity in opening their doors and sharing their wisdom.

Taking Amano-san's teaching to heart, we at NYrture have done our best to look far and wide across America for the best GMO-free soybeans to use in producing our natto. We will continue to do so.

Natto exploration (Birth of NYrture New York Natto. Part II)

In Japan, natto is an everyday staple food for a significant portion of the population, so many different natto manufacturers compete for grocery store shelf space. Supermarkets generally carry both national and local brands, but most of these are pretty similar in taste and all packaged in a standardized way-- stacks of three or four single-serving flip-top styrofoam boxes.

Foodie heaven can be found in the giant food halls (depachikas) located in the basements of nearly all department stores. In these markets, an amazing variety of exquisitely presented specialty edibles are sold and free sampling opportunities abound.

In depachikas, "artisanal" natto from small-scale producers are available; many of these are packaged in more traditional, eco-friendly ways and show more noticeable variation between makers--in quality, taste, freshness and packaging.

This one was packaged simply in folded water-resistant paper. Also, the beans here are much larger than those in popular commercial brands.

This one was made with even huger soybeans and packed in a lovely natural paper-thin sheet of pine bark folded into a triangle shape.

As is true for any food, fresh high quality natto is much more delicious than the cheaper, industrially-produced version.  Premium natto created by artisanal producers is made from carefully chosen soybeans, sourced from small (GMO-free) farms for their particular breed- and climate-dependent flavor/nutritional profiles and bean size, all of which can affect the progression of bean fermentation.

The best kinds of natto are generally produced on a small scale, may only be available in a local area and are delivered fresh without ever being frozen.  Natto is a living food containing live probiotic bacteria. Freezing and thawing natto kills most of these microorganisms and also negatively affects its taste and texture. To preserve all of its best qualities, New York Natto will always be fresh and alive, never frozen before sale.

How was NYrture New York Natto born? (Part I)

As a Japanese-American, I have enjoyed eating natto for much of my life. I was introduced to natto by my aunt during visits to see my grandparents in Japan. She would serve me what, to her, was a normal breakfast consisting of rice and natto, miso soup with clams and sometimes a pickled salad.  Born and raised in America, I thought this was pretty odd and may not have been entirely happy at first, but I did learn to love natto there.

In Japan, one can buy delicious fresh natto in just about any food shop. In a few places in America like NYC, natto may be found in Asian specialty groceries. However, I was always disappointed that the available natto is always imported frozen from Japan, packaged wastefully in non-recyclable styrofoam/plastic, and made from low quality GMO soy. I wished there was a good alternative.

I'm also a microbiologist and particularly interested in fermented foods made with the help of friendly microorganisms which contribute so very much to our health and to the health of our planet (see MISSION page). Natto (and its close relatives: see more recent BLOG posts) are the only widespread fermented food made with the benign microbe Bacillus subtilis. This bacteria is now recognized as an important member of our gut microbiome, the diverse community of microorganisms living inside of us.

So I decided to spend last summer in Japan with my sons to learn more about natto and how to make it. That is the beginning of the story of how the idea for NYrture New York Natto was born.
