Is there any special food for tenno tanjobi?

In Japan, it is common to celebrate birthdays with special foods, often including cakes and traditional dishes. For a "tenno tanjobi" (the Emperor's birthday), special events may feature elaborate kaiseki meals, which are multi-course dinners highlighting seasonal ingredients. Additionally, people may enjoy festive treats like "wagashi" (Japanese sweets) and "osechi" (traditional New Year foods, sometimes served on special occasions). However, individual celebrations can vary widely based on personal preferences and regional customs.
