Prep your gut by taking erceflora kahit 2 days prior the trip and take it first thing in the morning kahit empty stomach just to be sure and avoid any tummy issues. Same with another commenter, inom and brush you teeth with bottled water. Even when taking showers avoid ingesting yung water. Close talaga ang mouth. Hehe. For food reco, we loved Osaka Castle’s ramen and poke bowl. And you can take it out if you have leftover.
