Osaka is a city with a hectic pace and a population who like to work hard and play harder. Regarded as Japan's second city, the streets are strewn in neon and begging for attention. Visit Osaka Castle which is a well thought out reconstruction after the original was destroyed in WWII and marvel at the architecture of the Umeda Sky Building with its rooftop observation deck. Food culture in the city is strong with the unofficial slogan of kuidaore, which means eat until you drop, justifying a dazzling array of late night eateries suitable for all budgets. Spend an evening in an izakaya for tasty tapas style dining washed down with local beers.
