It was released in 1981 to commemorate the 25th anniversary of Coca-Cola's entry into Japan. The same bottle that was first released in 1956 has been restored and is in a paper box. The bottle is unopened, so the cola inside is still from 1981.Of course, I have not opened the package, so I cannot guarantee the contents. Since the sales agency is "Tokyo Coca-Cola Bottling Company", it is thought that it was issued only in Japan. All displayed products are guaranteed to be genuine. It is neither a pirated version nor an illegal copycat. Please note that these are the responsibility of the customer.
