Is it a bit narrow? The children of a nearby nursery school are playing well.

Itabashi Gymnasium Pool is also a good place.

Itabashi-ku designated monument Sander impression wheel monument This compactor wheel is an opportunity to produce black powder. The material is known as European marble. Purchased in Belgium by Saro Tarozaemon, a shogun who was designated to study in Europe to study ship operation, gunnery, gunpowder manufacturing, etc. in 1886 is. Sawa was reportedly working as a worker at the Koval gunpowder factory in Wetteren, Belgium, where he was borrowed from the foreman for drawings of carbonization kettles necessary for the production of gunpowder, and was instructed about the polishing machine. The Also, through the chief engineer of the plant, it is said that gunpowder and other explosives manufacturing machines have succeeded in insects. Sawa, who returned home in Kaiyo Maru in Keio 3rd year, will participate in the construction of the cannon and gunpowder factories of the Shogunate in Kita-ku, which was already planned by Tadanobu Oguri. Will be suspended, and Sawa will steer to Hakodate. Some of the gunpowder manufacturing machines imported at this time were transported from Takinogawa and loaded onto warships, but the trends in the grinding wheels are not known. Sawa later posted to the new government troops, but in 1877, immediately after being released, he served in the Ministry of Military Affairs and played a central role in the construction of an explosives factory in Itabashi. It was. In July 1894, the Ministry of Military Affairs asked the government to hand over a part of Itabashi Kanazawa Prefecture's residence (formerly Kaga Kanedo Shimodashi Hirao residence) to be used as a site for an explosives factory. The reason for this is that the power of the water wheel laid in the Shakujii River was an important condition for moving the sanding machine, as stated in the proposal book, “Akiyuki Hinomoto Moyo, convenient for the army.” was. same year In December, a part of the residence became an army arsenal and construction of a gunpowder factory began. In addition, at the time of the construction of the army department in the Ministry of the Ministry of Military Affairs, Seikan Sano (Sano Kanae), who was in charge of Western studies (military science), was appointed as the factory. It may have influenced the selection of the site. The gunpowder factory, which was completed in August 1894, began operations as the Army's “Artillery Honban Itabashi”, and black powder was produced using this compactor wheel. Gunpowder production affirmative with a polishing machine, turning the pressure wheel while pouring water, pulverizing and mixing sulfur, glass stone, and charcoal, sifting through particles, drying and commercializing was. In addition, the power of the vertical axis turbine (simple slansis turbine) by the water introduced from the Shakujii River is used as the power for rotating the polishing machine. The installation location is considered to be around the current 15-gamachi block, 2-caga, Kaga. This factory was later renamed “Itabashi Gunpowder Factory”, and the final name was the Tokyo 2nd Army Army Corp., Itabashi Factory (commonly known as “Niizo”). In 1907, the manufacture of unrelated explosives started at the beginning, and facilities and equipment were expanded. On the other hand, the production of black explosives that were difficult to handle and continued an explosion accident decreased. In the same year, production was discontinued in 39. Wheel Is no longer used. In March of 1912, as the disarmament proceeded both in Japan and overseas, the army diverted a crusher wheel that was no longer used. I carved about the history of and made it a monument. After the war, this monument is the Ministry of International Trade and Industry Although it was on the site of the Metrology Institute, it was relocated to the Kaga West Park with the relocation of the laboratory. Recommended by the Japan Society of Industrial Archaeology in 1985 It was recognized as an industrial heritage and became a ward registration monument (designated monument since 1995) in the following year.

A well-maintained park facing the Oji Shindo. There is a bicycle parking lot at the Higashiitabashi Gymnasium beside the entrance, and it has a shape that extends to the back. There was a police box (maybe) and the security seemed to be good.

The time of the soba cherry blossoms of Ishigami Ikawa is beautiful.
