Ryukakusan Building

The Ryukakusan Building is a modern commercial structure located in the Higashi-Kanda business district with functional office spaces and contemporary architectural lines. The building houses the headquarters of a pharmaceutical company and combines administrative areas with operational facilities.

The company was established in 1871 and transformed traditional herbal remedies into a modern pharmaceutical enterprise. The operation later became a pioneer in introducing new product categories to the national market.

The building reflects how traditional Japanese medicine practices have found their place within modern urban corporate spaces. One can observe the connection between historical healing methods and contemporary business operations in the heart of Tokyo.

The building sits in a busy commercial area with good access to public transportation networks. Its location provides direct connections to multiple transit lines in the central business district.

The company was the first in Japan to introduce throat lozenges as a mass-market product in 1967. This simple product became a staple in Japanese pharmacy shelves.
