- •While August has the significant Peace Memorial Ceremony, it is also peak typhoon season, posing travel risks and extreme heat.
- •October and November offer excellent weather and stunning autumn colors, but be aware that accommodation prices can be high due to popularity.
- •Early April is prime cherry blossom season, drawing large crowds and peak prices, making late March or early May potentially better value if flexibility allows.
