Hello! It's exciting to hear that you're planning to visit beautiful cities in Japan: Hiroshima, Okayama, and Tottori. Here are some travel tips to help you organize your trip better.

Best Time to Visit:
The best time to visit these cities is during their spring (between March and May) and autumn (between September and November) seasons. Cherry blossom season in spring and the Koyo season in autumn both provide breathtaking sceneries.

Route and Accessibility:
All three cities are well-connected to Tokyo and Osaka via the Shinkansen (bullet train). You can skip the hassle and enjoy the scenery by using Japan's extensive rail network. Alternatively, you can fly into Hiroshima Airport and then use buses or trains to reach the other destinations.

Accommodation and Booking:
Japan offers a variety of accommodations, ranging from luxury hotels to traditional Japanese Inns, called Ryokan. Booking.com and Agoda are well-known platforms where you can find and book your preferred accommodation well in advance.

Clothing and Essentials:
If you're visiting in spring or autumn, layer up your clothes as temperatures may vary. Carry an umbrella or raincoat as rain is not uncommon. Don’t forget comfortable shoes for walking. Sunscreen and hydrating products might be helpful due to the fluctuating weather.

Health and Safety:
Japan is known for its low crime rate, making it safe for travelers. However, standard precautions apply. Keep your valuables safe and secure, and be careful while crossing roads. Also, ensure to have your travel insurance in place.

Local Etiquette and Respect:
Japanese people hold their traditions and manners in high regard. It's good to learn some basic etiquettes like bowing while greeting, avoiding loud noises in public spaces, and removing shoes when entering a Japanese home or certain traditional inns and restaurants.
