Your arrival date is listed as '31st of September' which does not exist; please confirm the correct calendar arrival date (e.g., 2025-08-31 or 2025-09-30) so I can build a precise day-by-day plan.
Share interests (food and restaurant budget, temples/shrines, pop culture, shopping, museums, nightlife), preferred pace (relaxed vs packed), and where you'll be staying (neighborhood or hotel) so recommendations can be tailored.
Decide which day trips you want (Kamakura, Hakone/Mt. Fuji, Nikko, Yokohama) and whether you prefer guided tours or independent travel so I can schedule transport and timings.
