What's New in Ken Isshu

1.4.0

October 30, 2026

・Drive any course you've finished counterclockwise too: all 47 prefectures, 36 islands, the region courses and all Japan, so twice the courses. Switch with "Clockwise | Counterclockwise" on the map panel. The prefecture is on your left and its neighbors and seas on your right. Records, medals and rankings are separate for each direction, and your first counterclockwise finish earns a ticket. There are counterclockwise titles too, and the Prefectures list can switch to show your counterclockwise medals. ・More landmarks: every prefecture now has two or more, and each of the 36 islands has its own. ・The All-Japan Pass now includes everything: the three packs plus all 30 shelf cars, and future cars too (one-time purchase). ・Every car has been rebuilt with rounded, more realistic shapes (all but the go-kart, buggy and tractor). ・Car shelf Set 3: an EV, a monster truck, a formula car, a 10-wheel dekotora and a dekotora trailer truck (one at a time, or all 5 together). The trailer swings along behind you in corners. ・Voiced kana such as ば and ぴ for your plate, free. ・Where you're in this week's top 3, the map shows a gold, silver or bronze "You" sign, and you can get a notification when someone passes you (asked once, or in Settings > Notifications). ・Runnable courses now have a flag in the Regions and Islands menus. ・Fixed: in races, putting your finger back down near the nitro button sometimes didn't accelerate. ・Fixed: if you hadn't chosen a home prefecture, island and region records could show up under the wrong prefecture in the rankings.

県の形もわかっていい!

操作がシンプルで県の名産や形もわかって勉強にもなってとっても良い!

くせになる!

コースが県の形で面白いし、自分の車の上に名物乗っけれたり、ナンバー変えれたり、楽しい要素あります!
しかも県だけじゃなくて、島の名前とか海の名前とかもわかって軽い勉強にもなる(笑)
