Yakōchū

Weekly Famitsu described Yakōchū as a sound novel.

Mark Kretzschmar and Sara Raffel, authors of The History and Allure of Interactive Visual Novels, described the term used to primarily define Japanese games that rely on graphics and sounds instead of puzzles to tell a story and was more generally interchangeable with visual novels. In Yakōchū, there are narrative branches out into different stories depending on the choices the player makes.

In Yakōchū, the game's protagonist, named by the player, is the captain of a large cargo ship called the Daiana. Before setting off on a six-month voyage, the Captain is seen off by his lover, whom he plans to marry after the voyage. Besides the protagonist, there are other important crew members on board such as the navigator, the mechanic, a doctor.

As the ship sets sails from the shore, the crew begins to encounter various kinds of misfortunes. These can range from paranormal events, natural disasters, being attacked by monsters, and the deaths of the crew. Since there is only ocean outside the ship, the situation becomes even more alarming. The development of events depends on the player's decisions with the game having several endings.

In 1995, the Japanese video game magazine Famicom Tsūshin said that a new form of Japanese adventure games was on the rise with the advent of the sound novel genre, noting upcoming releases such as Yakōchū and Gakkou de atta Kowai Hanashi (1995). Prior to this, earlier games by Chunsoft such as Otogirisō (1992) and Banshee's Last Cry (1994) helped establish the genre.

Yakōchū was developed by Athena, a video company created by Sakae Nakamura in 1987. Nakamura recalled the development of Yakōchū, saying he wanted to create a sound novel for the company. He contacted the Japan Broadcast Writers Association and was introduced to their young writers club, which held an open call to create scenarios for Yakōchū. Nakamura said the person selected was a female office worker.

Reviewing the original release, the four reviewers of Famicom Tsūshin commented on the quality of the narrative. Two reviewers found the stories short, while another said the stories lacked major climaxes. One reviewer compared the title unfavourably to Chunsoft's Banshee's Last Cry, which they felt was superior due to its puzzle-solving elements. In the same magazine, critic Hamamura Tsūshin listed the game as the "Best Picks of This Week" for June 12 to June 18, 1995, saying it would potentially be what audiences who have completed Otogirisō have been looking for. In Game Criticism  the reviewer found there were too few variations on the story and that all the stories were too short.

In the Japanese book Perfect Guide to Nostalgic Super Famicom (2016), the game was included in their list of the top six horror games for the Super Famicom. Their overview said that there was no doubt that it was a good game, but said that if played consistently, some players may find it lacking due to its short run time.
