Omi Hachiman is the home of the Omi merchants, who built the foundations of Japan’s economy by doing business around the country from the Edo period (1603–1868). Guided by Ms. Masayo Shiraishi, deputy secretary general of the Omi Hachiman Tourism Association, the journalists toured the town with its traditional architecture that has been preserved, and went to the Omi Hachiman Municipal Museum (the former residence of the Nishikawa Clan) where they learned about the history and philosophy of the Omi merchants from the museum’s director, Mr. Masaharu Maesaka.

Next, the journalists visited the Hachiman-bori canal, constructed by Toyotomi Hidetsugu (who ruled the area during the Warring States period) and connected to Lake Biwa. The tour heard from Ms. Shiraishi about how the canal grew polluted in the late 1950s, but regained its former beauty thanks to efforts by local community groups.

The journalists showed interest in the amenities and daily goods people had in their residences in the past, asking questions about daily life such as how people stayed warm as they thought about history.

Yamasho Co., Ltd.

The journalists visited Yamasho Co., Ltd., a long-standing company in Nagahama, Shiga which makes moxa for use in moxibustion. Company director Mr. Tatsuki Oshitani explained the history of moxa production and the traditional medicinal herb culture around Mt. Ibuki, as well as explaining production methods and the concept of pressure points in Eastern medicine. Journalists from countries with less context for Eastern medicine seemed particularly interested in this concept. The journalists experienced moxibustion for themselves, gaining a deeper understanding of what it felt like and the effects of its heat.

Next, the tour went to Yamasho’s factory and heard from factory head Mr. Takashi Maekawa about how moxa is made. The journalists asked questions about where the mugwort used to make moxa grows and about any differences in quality and effectiveness based on price. Mr. Maekawa responded that moxa was made in a variety of places and at different price points, and that a higher price did not necessarily mean the product was more effective.. Instead, each product burned at a different temperature and speed, and had a different scent, so using them appropriately was important for treatment, according to Mr. Maekawa.

Marusan Hashimoto Co., Ltd.

As the final stop on the tour, the journalists visited Marusan Hashimoto Co., Ltd. in Nagahama. Since its founding in 1908, the company has made strings for traditional Japanese instruments such as shamisen and koto, and it is trusted by professional musicians not only in Japan, but around the world.

Mr. Hidekazu Hashimoto, president of Marusan Hashimoto Co., Ltd., briefed the journalists on the instrument strings his company made using silk from the Kinomoto-cho Society for the Preservation of Silk Strings for Japanese Musical Instruments (Tsukuda Heishichi Silk Reeling Workshop) and the current state of their overseas business, followed by the tour seeing instrument strings being made in the workshop. The journalists were able to film and photograph up close a demonstration of the traditional komayori technique, which Marusan Hashimoto is the only company in Japan to still use.

Next, the tour listened to a performance by Mr. Gashu Toyozawa, a professional musician, playing a futozao (thick neck) shamisen using silk strings made by the company, and experienced the rich sound made possible by silk strings.

The journalists asked Mr. Hashimoto about the reason behind the unique movements for komayori, carried out by two artisans at once, and the characteristics of silk strings compared to metal or polyester strings. There was also a question to Mr. Toyosawa about what he thought of the Marusan Hashimoto silk strings, and he replied that their strength was that they had a thick, deep sound which carried the sound throughout the venue even without a microphone.
