Japan’s Tokaido and Sanyo Shinkansen bullet train lines will introduce private compartments, dubbed “Supreme Class,” beginning in October. These compartments will offer passengers enhanced privacy with features including reclining seats and lockable doors. Tickets for the exclusive compartments will be available for purchase exclusively online. The new service aims to cater to travelers seeking a more luxurious and secluded travel experience. Pricing details have not yet been released, but the offering is expected to appeal to business travelers and those prioritizing comfort. The introduction of private compartments marks a new tier of service on Japan’s high-speed rail network. This upgrade reflects a broader trend in the travel industry towards personalized and premium experiences.
