If you have more time, visit the vibrant district of Asakusa, and try out the traditional cuisine at Asakusa Okonomiyaki Sometaro. For added culinary diversity, include Shibuya Katsukura's tonkatsu, Shirohige Cream Puff Cafe's Totoro-shaped cream puffs in your itinerary. You can still adjust your itinerary to explore other parts of Tokyo like Ueno and Ikebukuro, while if short on time, you can remove an item, or condense days two and three and visit Tomigaya area to enjoy different Japanese cuisine options.
