A crucial question you must ask yourself is how much time to allot to each city. For most people, the ideal breakdown is 2 full days in Tokyo and 4 full days in Kyoto (travel days are not considered full days). If you are more interested in modern Japan, then you could spend 3 days in Tokyo and 3 in Kyoto.

For a first-time visitor, the "Golden Route" typically requires at least 7 to 10 days to properly experience both cities. A balanced itinerary usually allocates 3 to 4 days for Tokyo, allowing you to explore diverse districts like the neon-lit Shibuya, the traditional Asakusa, and the high-end Ginza. This is followed by 3 to 4 days in Kyoto, which is essential for visiting major sites like the Fushimi Inari Shrine, the Arashiyama Bamboo Grove, and the Kinkaku-ji (Golden Pavilion). If you have 10 days, you can add day trips to nearby Nara (from Kyoto) or Nikko/Hakone (from Tokyo). While it is technically possible to "see" both in 5 days, the 2.5-hour Shinkansen (bullet train) journey and the sheer volume of cultural sites mean that a week is the recommended minimum to avoid burnout. Kyoto is often the highlight for those seeking traditional Japan, so many travelers prefer to spend a slightly larger portion of their time there.
