Before Nozawa transmigrated, his usual routine included playing Japanese games like "Taiko 2," "Persona," and "Heartbeat Memories." He'd also watch manga and anime like "Dragon Ball" and "One Piece," and if he had some free time, he'd even read Japanese web novels made in China.

Plus, since China and Japan are neighbors, economic and cultural exchange is basically unavoidable. In that case, taking the initiative to learn about each other makes sense—if you don't bother to understand other people's behavior, national traits, and history, are you just waiting to get screwed over the next time you deal with them?
