From Emperor of Japan: Meiji and His World, 1852–1912, by Donald Keene (Columbia U. Press, 2005), Kindle pp. 346-347:
On February 23 the emperor had word from John Bingham, the American minister, that King Kalakaua of Hawaii would be arriving in Japan on a round-the-world journey. The king would be traveling incognito, but he had some state business to transact: he wished to encourage Japanese migration to Hawaii and to sign a treaty with the Japanese government. He was accordingly treated as a state visitor, and Prince Yoshiaki was appointed as the commissioner for the visit. Two other officials were charged with entertaining the king.
Kalakaua arrived in Yokohama on March 4. He was greeted with twenty-one-gun salutes by Japanese and foreign warships anchored in the bay. When the boat sent by the Japanese to take the Hawaiians from the Oceanic to their hotel touched shore, they heard the Hawaiian national anthem, played with explosive vigor by a Japanese military band. They were astonished that the Japanese musicians had learned the anthem of so remote and unimportant a country. The king and the others of his retinue, touched, were all but in tears. Along the way to the palace where they were to stay, they noticed that the houses of Yokohama were decorated with crossed Japanese and Hawaiian flags. The king and his party were stunned by the welcome.
Kalakaua traveled to Tōkyō the next day aboard the imperial train and, after receiving an official reception at Shimbashi Station, proceeded directly to the Akasaka Palace. The emperor, following the etiquette of European courts that requires a monarch to receive a visiting monarch at the threshold of his palace, went to a room close to the entrance of the palace to meet his royal visitor. He was resplendent in a dress uniform studded with medals. The two monarchs shook hands. The Hawaiians, having been informed that the emperor normally did not shake hands, interpreted the gesture as a special honor. The two monarchs, after exchanging formal greetings, walked side by side into an interior room. W. N. Armstrong, the king’s chamberlain and the chronicler of his journey around the world, had heard that because of his divine origin, the emperor had never before permitted anyone to walk by his side; even the empress followed him. “But, for the first time in his own reign, and in those of his predecessors, he walked by the side of his kingly guest.”
The empress was waiting for the royal visitor in the audience chamber. Meiji presented Kalakaua to the empress. “She did not rise, but returned the king’s salutation with the least movement of her head and eyes.” Sueko, the daughter of Inoue Kaoru, who had spent several years in England, served as her interpreter. (Armstrong wrote that she spoke perfect English.) Refreshments were served, but the Hawaiians, having been previously informed that they should not eat in the presence of the emperor, declined them.
