Oshiro EXPO 2023, Japan's largest castle festival, was held from December 16-17, 2023, at Pacifico Yokohama North in Yokohama. This year marked the 8th edition of the event, which aims to promote castle culture, attract tourists, and foster interaction with castle enthusiasts. The previous event drew approximately 15,000 visitors, but this year's attendance surpassed that record, making it the most successful to date.
At the event, Yoshikuni's Joshu Sanada Project "Sanada Sukajan" (souvenir jacket) was displayed at a corner of the Sengoku Soul booth, and "Nagoya Castle T-shirts" from another label were also sold. These products were very popular among history enthusiasts, and many visitors picked up the items, engaging in interesting conversations.
Particularly noteworthy was the "Sanada Sukajan" sold for 666,666 yen (tax included), which attracted many people despite its high price. Visitors were offered the chance to try it on, and the booth was visited by radio DJ Chris Glenn, Sengoku Soul President Tomohiro Suzuki, Morichika Chosokabe, a descendant of Lord Chosokabe Motochika, Oshiro-kun, who is active on TV Asahi's "Hakase-chan," Professor Yu Hirayama, a historical consultant for NHK's historical dramas, Sakon Shima of the Sekigahara-gumi, members of the Iwatsuki Bushotai, Tadakatsu Honda of the Great Ieyasu "Aoi" Bushotai, Chibi Naomasa and Yasumasa Sakakibara of Gamushara, and the son of the Sekigahara Armor Museum.
