Japan's first eye drops
The first eye drop in Japan was "Seikisui" released by Ginkō Kishida, who was said to be a pioneer of the times, in the 3rd year of Keio. It is said that this prescription was taught by Mr. Hepburn, an American who was a missionary and ophthalmologist in Yokohama at that time, and the prescription was zinc sulfate 1: water 450.
Around the 30th year of the Meiji era, the water was declining. At that time, eye drops began to be known to the world at "DAIGAKU Eye Drops" released by "Taguchi Santendo", which had a cold medicine called "Hebrin Maru" as its main product in Kitahama, Osaka, in the 9th year since its establishment. The name "Daigaku eye drops" became even more widespread in the Tokyo Asahi Shimbun in August 1902, with a confident advertisement stating that "as the world progressed, such fine eye drops were made." I went.
In the history of more than 100 years, the most notable thing was the appearance of the double-ended glass eye drop bottle, which should be called the revolution of glass containers in 1952. This container had rubber caps attached to both mouths, one was the eye drop opening and the other was the finger pressing part.
However, during the Pacific War, the supply of rubber dropped sharply, so a "bite tataki" eye drop bottle was developed that taps the closed part of the finger press to drip. Plastic synthetic resin began to be used in Japan in the latter half of the 1945's, and application development for eye drop containers has also started. One of them was a PP (polypropylene) container, which had the drawback of being translucent and hard, but later became the prototype for medical eye drop containers.

At the time of the launch of Daigaku eye drops, a cup of soba noodles cost 1 sen and 5 liters, but Daigaku eye drops cost 10 sen each. The price was raised from 20 sen around 1918 to 30 sen around 1945, when the Pacific War began. After that, it was 80 yen in 1945 and 2.50 yen in July 1945 at the end of the war according to the "Price Control Ordinance".
