Clothing Tips for Visiting Japan in Summer

When it comes to dressing for the Japanese summer, these practical tips will keep you comfortable and respectful:

  • Opt for Breathable Fabrics: Prioritize light and airy materials like cotton, linen, or rayon. These choices assist in staying cool and preventing excessive perspiration. Avoid synthetic fabrics that can trap heat and moisture.
  • Choose Light Colors: Dress in light-colored attire that reflects the sun’s rays, ensuring you remain refreshed. Steer clear of dark hues that can absorb heat, making you feel even hotter.
  • Carry Raincoat or Umbrella: Be prepared for sudden summer rain by carrying a lightweight raincoat or umbrella. For cooler days and evenings, consider pairing a sweater or cardigan over a long-sleeved shirt.
  • Respect Local Customs: When visiting temples and shrines, it’s crucial to dress modestly and respectfully. These locations hold deep cultural significance, so avoid wearing revealing clothing like shorts, skirts, tank tops, or camisoles. Opt for jeans or trousers, ensuring they aren’t overly tight or distressed.
  • Footwear Matters: Comfortable, easy-to-slip-on shoes are a must, as you might need to remove them when entering traditional Japanese homes or temples. Choose sandals, sneakers, or flats, but avoid high heels or boots that could be challenging to take off.
  • Stay Cool in the Sun: Shield yourself from the sun by wearing a hat or using an umbrella. Additionally, it’s a good idea to have a small towel on hand to wipe away perspiration.
