When planning pharmaceutical packaging, the package size for the product is important for determining the basic package concept. Initially, the sales unit for herbal medicines was the weight; however in 1868, around the early part of the Meiji era, Japanese and Western units were being used and the sales unit was confusing. Since the Edo era, the packing size for OTC medicines was adopted using weight, numbers, dosage or treatment period. These were devised in various ways in consideration of convenience for the consumer, but the concept was not simple. In 1887, from the time that the first edition of the Japanese Pharmacopoeia came out, use of the metric system began to spread in Japan. Its use spread gradually for use in the package size of pharmaceutical products. At the time, the number of pharmaceutical units (i.e., tablets), became the sales unit, which is easy to understand by the purchaser.

During World War II, the amount of camphor production did not decrease, since it was used for munitions. At that time, camphor was not use for moth repellents, are not a life supporting necessity. The factory that took charge of camphor production was busy producing medicine for military use. Due to the war, an abnormal situation in the factory arose when the procurement department requested supplementation because of reinforcement of a lack of materials. Additionally, in the home, the use of moth repellent for clothing was not a concern. Of importance where was ensuring sufficient food to survive. The supply of "Fujisawa Camphor" for home use started in the post-war days, 1947.

The selling price of "Fujisawa Camphor" has increased 1,000-fold in the 100 years since it first went on sale. This 1,000-fold increase is not high at all. The price of "Fujisawa Camphor" was not low in the 1980s, one of grounds for setting the price was the damage caused by moths to expensive Japanese clothes and curios. For packaging in the Edo era, being wrapped in paper was the mainstream form, but modern-age packaging shifted to a cardboard box. As for "Fujisawa Camphor", a beautiful design was created for the cardboard.

In the Meiji Era, the concepts of consumers did not exist; however, customers were certainly valued at that time based on the policy that "the customer is always right". Customers were always considered as guests, and there were no conflicting matters with manufacturers. The sales agency for Fujisawa camphor, Fujisawa Company, took up a positive attitude towards customer services. First, the company excluded imitation products in order to protect customers from poor quality, and second, the company released data regarding camphor comparisons and effects with other insecticides. At that time, they seemed to fear being talked about in terms of the mistaken use of camphor. The company commissioned a public research laboratory to study the interaction of camphor and precious metals, and made an appeal to customers for the truth.

Newspaper advertisements were frequently available as one way of communicating news about new products to the general public during the middle of the Meiji Era. The first newspaper advertisement of "Fujisawa Camphor"' appeared in the Osaka Asahi on June 1, 1989. At that time, the newspaper advertisements of OTC were brilliant and the space taken by them was large, in some cases covering a full page. They appeared daily. However, the ad for Fujisawa Camphors was small and simple. The appeal points of the Fujisawa Camphor advertisement were as follows: 1. Fujisawa Camphor, crystals of refined camphor, are hard and colorless.2. It is effective for insecticide and prevents moisture.3. It is widely used by governments and the military.4. It removes bad smell to protect against infectious diseases.

Newspaper advertisements were the predominant medium in informing people about new products midway through the Meiji Era. Subscribers to these newspapers, however, were still limited. At the time, expositions were wildly popular. Seizing the opportunity , in 1903 Fujisawa promoted his "Fujisawa Camphor" through aggressive advertising at the 5th Domestic Industrial Exposition in Osaka. The advertising proved to be a success, as Fujisawa took 2nd Prize of the exposition.

A troublesome task in the daily life of the Edo era was ridding houses of harmful insects such as mosquitoes, fleas and clothes moths. People commonly drove away mosquitoes by making smoke. They hung their clothes or books in the air to keep them free from moisture. This was effective in protecting them from becoming moldy or being damaged by insects. Various medicinal plants were used to eliminate harmful house insects or agricultural vermin. Camphor was a variety of insecticide, but it was not popular in early Edo times because it was not easily available then. But in the end of Edo period, camphor became popular as a moth repellent.
