"Nihon Jōmeguri" is a stamp rally (location-based game) that uses GPS location information to visit 3,000 castles that existed throughout Japan, primarily from the Sengoku period, including the Top 100 Castles of Japan and the Top 100 Continued Castles of Japan. This app is enjoyable for everyone, from castle, history, and Sengoku period enthusiasts to beginners.

■Castle Stamp Rally (Location-Based Game)
Just press the "Castle Attack" button near a castle. This stamp rally is easy to operate. Check the locations of 3,000 castles nationwide on the map as you complete the stamp rally. You can also send location information to your car navigation app or use DENSO's "NaviCon" app to send the castle's location to your car navigation system.

■Castle Data, Photos, and Reviews
Browse basic data, photos, and reviews for 3,000 castles across Japan. There are over 50,000 reviews and over 400,000 castle photos. Use this information as reference when visiting a castle, or browse the information and photos to find a castle you want to visit at your leisure. Enjoy it for a variety of purposes.

■Sengoku Warlord Collection
Collect local Sengoku warlords along with castles. Collect over 1,000 Sengoku warlords from across Japan, including Oda Nobunaga, Date Masamune, and Sanada Yukimura.

■Castle Lord Competition
Even if you've already conquered a castle near your home or workplace, register your location multiple times and become the top ranked castle, earning you the title of "Lord" of that castle. Enjoy this game even if you don't get to go out much, such as on vacation or business trips.

Plus, there are plenty of free features you can enjoy for years to come, beyond just a stamp rally (location game), such as "Castle Construction," where you can choose your favorite territory and buildings like castle towers and turrets to create your own castle; "History Quiz," where you can take daily challenges related to the Sengoku period and castles; and "Nicknames & Ranks."
