About us

A triangle zone that the peoples and culture gather,
which created by the ceramic ware production company
Maruhiro Inc.

We are Maruhiro Inc., the ceramic ware production company based in Hasami town, Nagasaki Prefecture.
The following three facilities we have completed, the private park “HIROPPA”, the multi-purpose space “OUCHI”, and the head office “KOUBA”, are located in a peaceful place along the river that runs through Yumuda-go, Hasami town. The three facilities are adjacent to each other within 1 or 2 minutes on foot.

We have various ideals and dreams for this place. We want our friends and new acquaintances to feel free to come see us and have a good time here. We want the local citizens to visit here like a routine. We also want to make here such an attractive place that will become a top travel destination. By doing so, we will be able to build a new connection with many people regardless of where they live, generation, or gender.
By bringing together people and cultures, we eagerly desire to create an environment where the children who will be leader in the next generation can grow up, and give back to the craftsmen in this production area who have supported Maruhiro so far.

Park & Shop


HIROPPA is a private park created by Maruhiro in 2021. It was born from the desire that the ceramic production company Maruhiro wants to provide a place where the local children who grew up in a ceramic production area could laugh, play and become interested in the crafts made in Hasami town, which is called “Hasami-yaki” in Japanese, in their future.
This lush green park is designed with terrain instead of installing standard playground equipment. It is a place filled with Maruhiro’s fun gimmick and art, and there is Maruhiro flagship store with coffee stand so visitors can also enjoy having a coffee break and shopping here.

The site area of HIROPPA is approximately 4,000 square meters, and the lawn is spreading out wide so children can have a blast running around in this park. Additionally, various kinds of trees and plants such as zelkova, cherry blossoms, maples, kiwis, apples peaches and walnuts, that can be enjoyed throughout the year, are planted in this park.

The playground, which is fused with the landscape, is designed to let children decide freely how to play with their own imagination. There are sculptures and murals designed by domestic and overseas artists that Maruhiro has connected through Hasami-yaki projects. The barrier-free passages are also available, so we hope that visitors with stroller or in wheelchair can have a fun here in HIROPPA.

MultiPurpose Space


We have created the new “functions” and “values” of the Japanese-style house, which is built with Japanese traditional construction methods in 1932, by utilizing the current condition of building as much as possible, but also by changing the impression boldly. It is a space to hold various exhibitions or popup events. And, on the other hand it has a function as the artist-in-residence, so the artists will be able to stay at this facility and concentrate on creative activities.

What’s Hasami-yaki?

Hasami-yaki is the traditional crafts that has been inherited for over 400 years in Japan

Hasami-yaki is a general term for ceramic ware produced in Hasami town, Nagasaki Prefecture, and has produced a lot of daily use ceramic tableware since Edo Period, 1603-1867. Since ceramic products were very expensive at that time, there is a history that Hasami town succeeded in mass-production them and those became popular throughout the country as common tableware for general public. The name Hasami-yaki came to be known relatively recently, because it has been distributed as a part of Arita-yaki in the past. Arita is the famous ceramic production area located in Saga Prefecture and it is just next to Hasami town.
Unlike other Japanese ceramic production areas, Hasami-yaki does not have a traditional style that can express its own uniqueness, so there are various designs and different kind of material are used flexibly. Such variety and flexibility are surely the most notable character of Hasami-yaki. Even now, 20% of the daily tableware in Japan is produced in Hasami town, and Hasami town continues to create products that meet the needs of the times.

Many craftsmen are involved in the production

The total land area of Hasami town is about 56㎢, and the population is about 15,000 people that approximately 30% of the population in this town are involved in ceramic-related work. Hasami town has a history of emphasizing the production efficiency under the specialized “division of labor system” in which the craftsmen are divided for each production process, such as clay manufacturers, mold factories, bisque ware producers, and pottery.


Maruhiro is a ceramic production company that develops and distributes products

Maruhiro Inc., which has started its business as a street vendor in 1957, is a company that develops and distributes ceramic household goods such as tableware and interiors called “Hasami-yaki”, the original crafts of Nagasaki Prefecture. Maruhiro is a “ceramic manufacturer” that does not have its own factory. Hasami-yaki is produced by the specialized “division of labor system” in which the craftsmen are divided for each production process, and Maruhiro plays a role as a bridge between these craftsmen. Maruhiro requests the craftsmen in each process to produce products with its own designs. Then Maruhiro distributes those finished products to both Japanese and overseas markets as a “trading company”. We Maruhiro always want to be a joyful company in anticipation of the next generation that will not be bounded by any stereotypes as ceramic production company.
