The Los Angeles Dodgers gave Shohei Ohtani an unprecedented $700 million contract hoping to drive interest — and the dollars that come with it — from fans across the Pacific. It seems to be working. He’s the main attraction on the field as the Dodgers and Chicago Cubs open the MLB regular season on Tuesday and Wednesday at the Tokyo Dome. He’s also producing off the field for MLB and the Dodgers, the marquee name at a sprawling souvenir store that fills an exhibition hall in the Tokyo Dome complex. MLB calls the setup its “largest ever special-event store.”
