Log the castles you visit<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Select the prefecture, search for the castle name and pick it from the list. You can save the visit date, a photo and a short note together. Because castle names are built in, castles with alternative names, such as Takamatsu Castle (Tamamo Castle), are always recorded correctly.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" width=\"432\" height=\"851\" src=\"https:\/\/www.shirolog.info\/wp-content\/uploads\/2026\/10\/shirolog-app-record-en.webp\" alt=\"Record screen of the ShiroLog app: choose the prefecture and castle, then save the visit date, a short note and a photo\" class=\"wp-image-2276\" style=\"width:300px\" srcset=\"https:\/\/www.shirolog.info\/wp-content\/uploads\/2026\/10\/shirolog-app-record-en.webp 432w, https:\/\/www.shirolog.info\/wp-content\/uploads\/2026\/10\/shirolog-app-record-en-152x300.webp 152w\" sizes=\"(max-width: 432px) 100vw, 432px\" \/><figcaption class=\"wp-element-caption\">Record screen: choose the prefecture and castle, then save the date, a photo and a note<\/figcaption><\/figure>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\">2. See your total castles and recent visits<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The home screen shows the total number of castles you have visited, the number per year and your most recent visits. Each visit appears with its photo, so it is also a nice way to look back on your trips.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" width=\"432\" height=\"862\" src=\"https:\/\/www.shirolog.info\/wp-content\/uploads\/2026\/10\/shirolog-app-home-en.webp\" alt=\"Home screen of the ShiroLog app showing total castles visited, castles per year, and recent visits\" class=\"wp-image-2275\" style=\"width:300px\" srcset=\"https:\/\/www.shirolog.info\/wp-content\/uploads\/2026\/10\/shirolog-app-home-en.webp 432w, https:\/\/www.shirolog.info\/wp-content\/uploads\/2026\/10\/shirolog-app-home-en-150x300.webp 150w\" sizes=\"(max-width: 432px) 100vw, 432px\" \/><figcaption class=\"wp-element-caption\">Home screen: total castles, castles per year and recent visits<\/figcaption><\/figure>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\">3. Take on missions<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">ShiroLog has more than 50 missions. Visiting castles that match a theme raises your progress, and when you have visited them all you get a &#8220;Mission Accomplished&#8221; screen. New missions are added regularly.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>National treasures and original keeps<\/strong>: for example, the five national-treasure castle keeps (Matsumoto, Hikone, Himeji, Matsue and Inuyama)<\/li>\n\n<li><strong>Warlords<\/strong>: castles linked to Oda Nobunaga, Toyotomi Hideyoshi, Date Masamune, Asakura Yoshikage, Azai Nagamasa and more<\/li>\n\n<li><strong>Themes and regions<\/strong>: castles by the sea, original keeps of Shikoku and more<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" width=\"432\" height=\"862\" src=\"https:\/\/www.shirolog.info\/wp-content\/uploads\/2026\/10\/shirolog-app-missions-en.webp\" alt=\"Missions screen in the ShiroLog app listing favorite, in-progress and completed castle missions such as Oda Nobunaga's Path\" class=\"wp-image-2278\" style=\"width:300px\" srcset=\"https:\/\/www.shirolog.info\/wp-content\/uploads\/2026\/10\/shirolog-app-missions-en.webp 432w, https:\/\/www.shirolog.info\/wp-content\/uploads\/2026\/10\/shirolog-app-missions-en-150x300.webp 150w\" sizes=\"(max-width: 432px) 100vw, 432px\" \/><figcaption class=\"wp-element-caption\">Missions screen: see at a glance which castles complete each mission<\/figcaption><\/figure>\n<\/div>\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" width=\"432\" height=\"866\" src=\"https:\/\/www.shirolog.info\/wp-content\/uploads\/2026\/10\/shirolog-app-mission-complete-en.webp\" alt=\"Mission Complete screen in the ShiroLog app after finishing a castle mission\" class=\"wp-image-2277\" style=\"width:300px\" srcset=\"https:\/\/www.shirolog.info\/wp-content\/uploads\/2026\/10\/shirolog-app-mission-complete-en.webp 432w, https:\/\/www.shirolog.info\/wp-content\/uploads\/2026\/10\/shirolog-app-mission-complete-en-150x300.webp 150w\" sizes=\"(max-width: 432px) 100vw, 432px\" \/><figcaption class=\"wp-element-caption\">When you complete a mission, a &#8220;Mission Accomplished&#8221; screen appears<\/figcaption><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\">How to Use It (3 Steps)<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Install ShiroLog from Google Play.<\/li>\n\n<li>When you arrive at a castle, open &#8220;Record&#8221;, choose the prefecture and castle, and save a photo and a note.<\/li>\n\n<li>Open &#8220;Missions&#8221; and choose your next castle.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">Why I Made ShiroLog<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">I made ShiroLog together with my son, who loves castles. When you are walking around a castle, detailed settings and lots of typing get in the way. So I kept the features simple, so that all you need to do is choose a castle and save a photo and a note. My son uses it himself to check that it is easy to use.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FAQ<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Q.
