A Choko is a small ceramic cup used for drinking sake or as a dipping sauce container for soba noodles.
There are theories as to where the name “choko” came from.  One of them says that the word was derived from “choku”, a small dish used in a ceremonial table setting during the Edo period.  Another legend says that choko, which is written “boar’s mouth” in Chinese characters, was named after a boar’s snout, which is wide on top and narrow on the bottom.
When warming up sake, people are advised to consider what the temperature of it will be after it is poured into the choko. For example, when sake is heated up in a Tokkuri sake flask to 40°C, the sake, after being poured into the choko will be around 35°C, or approximately body temperature. It is then called “hitohada-kan (body warm sake)”. There are other elegant names to describe sake temperatures such as hinata-kan (sun warm sake), ryou-bie (cool sake) and hana-bie (flower cool sake).
Soba-choko, which is mainly used as a dipping sauce container for soba noodles, has many different patterns such as the ishigaki (stone wall) pattern and the karakusa (arabesque) pattern. Soba-choko is also used for a variety of other purposes.

The name of Toshiga Waterfall comes from the resemblance of the waterfall's shape to a toshi bottle of sake.

Toshiga Waterfall is approximately 48m high and 27m wide, and is one of the most prominent waterfalls of the Adatara Mountains.

There is a legend that a dragon god lives deep within the basin of the waterfall and would bring rain to the region if a young woman was sacrificed. It is said that after hearing this, the daughter of the regional lord plunged herself into the basin, and saved the lives of countless villagers who were suffering from drought.

Due to the abundant water flow and high water quality, part of the river is blocked in order to secure water for daily use, irrigation and aquafarming.

There is a hiking course near the waterfall; it passes through a rich natural area, well maintained with rest spots and signposts. It is a popular spot for cooling off in the summer, and viewing the reddening leaves in autumn.

The Sanshuu-Izutsu-Yashiki is an estate found in Hikita, Higashikagawa-shi, Kagawa Prefecture. The building was a famous old izutsuya store, which brewed soy sauce and sake.
   The history of this estate dates back to 1692, when the reputation of the izutsuya stores, which started the soy sauce business, spread as far as the Kanto region. In 1913, the Sanshuu-Izutsuya started to brew sake, and by 1920, was making shouchu (another kind of liquor) as well as mirin (a kind of condiment used in cooking). At their most productive, the Izutsuya was considered the best merchant family in all of Hikita.
   Despite the reputation and respect the Izutsuya had gained up until 1989, by 1997, the old Izutsu-yashiki had become vacant. The existence of this historic example of old architecture was in danger, but, thanks to petitioning by local residents, the house was acquired by the town of Hikita. It was renovated and reopened as the Sanshuu-Izutsu-Yashiki.
   Currently, the house is at the center of a resort area, and has become an important site revealing something of the history of soy sauce- and sake-making in Japan.
