About the Japan visa for travellers from Uganda
Japan attracts travellers from Uganda for tourism, business, academic exchange and conferences. Applications are submitted to the Embassy of Japan in Kampala, and the embassy expects a complete, well-organised file.
The document that distinguishes a Japanese application is the schedule of stay: a day-by-day account of where you will be and what you will do, with corresponding accommodation. Where someone in Japan is inviting or supporting you, a guarantor letter and their supporting documents are also required. Both need care, and both are why applications get returned.
