Small Museums Top eleven tourist sites 1. The Kanda Area 7. Tokyo Tower 8. Imperial Palace Area 11. WHAT TO WEAR Casual clothes are fine for sightseeing but for business, because so much rests on appearance in Japan, one can never be too smart.
Warm clothing is advisable for winter.
Although the temperature doesn't fall much below zero, the wind-chill factor can be quite high. Wet weather gear and boots wouldn't be in the way either - occasionally it snows, but this usually turns to slush. Even if the temperature is high people still tend to have a winter look about them. June to early July is the rainy season. It's generally too humid for rain gear - umbrellas are best.
