Adobo is one of the easiest dishes to cook in Japan: soy sauce, vinegar, garlic and pork belly are in every supermarket. For sour and fruity flavors, Japanese citrus does a great job.
Everyday supermarkets cover most Filipino home cooking. Filipino grocery shops (often near churches and in larger cities) and online shops sell sinigang mix, bagoong and banana ketchup.
