A convenient box-shaped handmade pure copper grater with a stainless colander and a stainless container.
It has sharp perforations on the surface of copper plate. It can make delicious grated radish keeping original taste of radish and its
juice. It is suitable for grating Japanese radish. Grated Japanese radish is called Daikon Oroshi.
This grater's perforations are so sharp and grate them well because of being hand made by skilled Japanese craftsmen.
So you can grate them lightly with this and make delicious Oroshi.

The key to make the finest oroshi is uneven sharp perforations by hand.


The copper plate is tighten with a roller. Thus, it gets firmer and the sharp perforations on it gets more tough.

Moreover, the sharp perforations are made by hand,so they are not in a line and each of them is a little different size. As a results, ingredients are caught with them easily, so you can grate food efficiently. This is the most different things from mass produced products which all the forms are decided on.

It is superior in durability, it will be usable for the decade under heavy use by professional chefs. In addition it can be repaired three times.
Therefore,it can be used for 40 years. It will be able to used in your life time.


This hand made copper graters are made by Ohya factory in Japan one by one. It has been loved by a lot of people including professional chefs in Japan for many years.

This is a new product of Ohya factory. It becomes the box form with a convenient colander and a handle having the original firm copper plate and the sharp perforations.

First, it has a handle to fix the body. If you hold the handle firmly and grate a radish ,you can make oroshi too easily and too speedily.

Secondllys it has a convenient colander. Surplus juice of radish is purged through the network of the colander. So you can enjoy crunchy texture of radish without surplus juice.

I compared three types of graters by actually using.


Ohya's grater, ceramic grater, and aluminum grater.

First I tried the ceramic grater. I felt like I was grinding the radish with strong power and crushing the radish than grating, because the saliences on the surface were not so sharp, delicious soup of radish came out more and more. Actually the juice has good taste,so it's a pity to waste it. Since the juice went out from the inside of the radish,the completed oroshi was soggy and was not volumy. It was a hard work. I turned the radish up down, right or left on it.

Secondly I tried an aluminum grater. It was a little easier to grate than ceramic one. But the oroshi was also soggy and not volumy . It may cut too finely, so it was hard to feel the taste of delicious Japanese radish.
On the other hand, ohya's hand made copper grater has so large and sharp perforations on its plate. The perforations cut radish into pieces. The radish pieces were not too small. So the each piece may be able to keep delicious juice inside. It was crunchy, juicy and tasty.


※The picture shows a comparison between the oroshi grated with Ohya's one and ceramic one. Please look at this. There is a difference in the volume. It is obvious to the eye.

How to Care


After use,please wash it as soon as possible, it is difficult to wipe off water with dish cloth because of the rough surface. So you should through hot water on it and dry with remaining heat.

please scrape the fiber of vegetable and fruits which got into the ditch with tooth brush.

The copper plate gets plated, but it will discolor. Please continue using thinking it has taken an antique look.

At least more than 10 years is okay, but if the cutting quality gets worse, please contact us.[takuminohako@gmail.com] Craftsman of Ohya repairs it. The old sharp perforations are cut off and the copper plate gets plated again. New sharp perforations are made by the craftsman. When your grater comes back from repair, it will seems to be new. It will be shiny although there are traces of cutting old sharp perforations.
(The charge for the work is at half price of the product's price.)

The grater on the right side of the photograph was made by Ohya's predecessor He continued using it more than 40 years. It is exactly usable throughout the life.

Interview to Mr Ohya.

A grater that can make delicious oroshi.


--- What is the goodness of the copper grater?

We hit the copper plate with a thickness of 2 millimeters again and again to tighten it and then we start to make sharp perforations. By doing so, the strength of the copper increases, so sharp perforations can be made on the plate. Stableness increases.
And because we make the size of each sharp point delicately different, it can catch vegetable's surface efficiency. And we also make the sharp point a little bit big,therefore each pierce of the completed oroshi is big and it keeps water. Tasty crunchy oroshi is completed. It is the taste only by the handicrafts.
