A Day in the Life of Omori’s Nori Fishermen

Nori production in Omori 
centered around midnight work.

Around 1:00 a.m., 
The harvested seaweed,
long and thin like wakame,
was finely chopped 
in a process called “norikiri.”

Around 3:00 a.m., 
The work of “nori‐tsuke” began — 
spreading the chopped nori 
into the familiar size 
of roasted seaweed sheets. 

Around 7:00 a.m., 
As the sun rose, 
the drying process, 
“nori‐hoshi,” 
would begin. 

During harvest season,
this cycle was repeated
every single day.

It is said
they had only
about two days off per month.

The Life of a Nori Fisherman

Omori’s nori fishermen
lived a semi‐fishing, semi‐farming life.

Yet it is said 
that nori alone 
could provide 
a year’s worth of income. 

Entire families worked together. 
In addition, many seasonal workers 
came from places such as 
Sagae City in Yamagata Prefecture  
to support nori production in Omori. 

Current Nori Production Near Tokyo

Nori cultivation in Tokyo 
has come to an end. 

However, 
nori‐making itself 
has not disappeared. 

While the Ariake Sea is well known, 
in the Kanto region 
nori is still harvested 
in cities such as 
Futtsu and Kisarazu  
in Chiba Prefecture.

On the day of the experience,
nori from Futtsu was used.

The Skill of the Nori Fishermen

It is said 
that skilled fishermen in Omori 
could spread 
250 to 300 sheets 
of nori per hour. 

The work required 
refined technique 
and intense concentration. 

What Is “Nori‐tsuke”?

On a screen (nori‐su),
a wooden frame (nori‐tsuke waku)
is placed.

Finely chopped nori 
is scooped with a measuring box 
called a jubako 
and poured evenly 
into the frame. 

In the experience program, 
each participant performs this process twice. 

Experience as Inheritance

In alignment with the harvest season,
the event is held monthly 
from autumn through early spring.

A Popular Hands‐On Event

Most participants 
are families with elementary school children.

Each session attracts many visitors 
and remains a highly popular event.

It offers a rare opportunity 
to experience and learn 
the history of Omori’s nori production firsthand.

The Finished Nori

Participants may choose
postal delivery (paid)
or in‐person pickup.

When it arrives,
lightly roast it
until it turns green
to enhance its flavor.

In Closing

Otapedia hereby registers  
the experience program 
held at Omori Nori Museum 
as an “Unrecognized Local Heritage of Ota City.”

Otapedia seeks to revive 
the memory of Ota City.

We turn our gaze once more 
toward those 
whose names are fading,
bringing them back 
to the shore of memory.

Even if their activities 
or traces disappear,
we will carry forward 
the marks they left behind 
into the future.

These designations are 
original to Otapedia 
and are not official recognitions 
by Ota City.
