Ojousama Express

Ojousama Express is a love adventure game set on a cross-country luxury train traveling across Japan. The journey takes a total of 15 days, with the train stopping at various cities and tourist destinations throughout the country. The protagonist is taking the trip hoping to meet girls, and many lovely ladies will get on or off the train at different stops along the trip.

The game is generally divided into sections where the train is running, and sections where it is stopped at a destination. While the train is running, the player can move between the cars, looking for girls to talk to; characters have no fixed schedules, but rather will move on their own based on their preferences and current relationships. In addition to the passenger cars, there is also a shop to buy guides for the next stop, a restaurant to meet up with the girls, the conductor's car where hints can be had, and an entertainment car with a selection of minigames.

At each of the various stops, the player can explore the area and ask the various girls out on dates. Depending on the player's actions and relationships, a girl may remain on the train longer than she'd originally planned, or the protagonist may disembark early with one of the girls leading to various endings.
