When traveling in Japan with the following average temperatures, the recommended clothing is as follows:
Average temperature: 25 degrees Celsius or higher
Light and breathable clothing such as cotton T-shirts, shorts, or sundresses. Protect against heat by wearing a hat, sunglasses, and using a parasol or umbrella. Using a fan or carrying a hand-held fan may also provide relief. Be sure to hydrate frequently to avoid heat stroke.
Average temperature: 20-25 degrees Celsius

Average temperature: 16-20 degrees Celsius
Light clothing with a light layer such as a cardigan, denim jacket, or light sweater.
Average temperature: 12-16 degrees Celsius
Light to medium clothing such as a sweater or long-sleeved shirt and pants, light jacket.

Warm clothing such as a sweater, long-sleeved shirt, pants, and a coat or jacket.
Average temperature: 5-8 degrees Celsius
Warm clothing such as a sweater, long-sleeved shirt, pants, and a coat or jacket. Wearing a hat, gloves, and scarf can also provide added warmth. In Japan, specialty clothing stores such as UNIQLO sell underwear made from fibers that absorb moisture such as sweat and generate heat. For example, UNIQLO’s “HEATTECH” underwear is recommended because it is thin and lightweight, yet has high heat retention properties. Disposable heat packs sold at drugstores and convenience stores are also effective in cold weather.
Average temperature: less than 5 degrees Celsius
Warm clothing such as a sweater, long-sleeved shirt, pants, and a coat or jacket. Wearing a hat, gloves, scarf, and insulated boots can also provide added warmth. Consider layering clothing for added insulation.

Comprehensive checklist before traveling to Japan
Book hotels
Book early before the hotels are fully booked
Japan offers a range of accommodations, from traditional ryokans to modern hotels. Popular platforms like Expedia and Agoda often have a wide selection, but also consider local sites like Rakuten Travel. In big cities, staying near a major train station like Tokyo's Shinjuku or Kyoto's Kyoto Station can save you a lot of commuting time. Remember that Japan's peak tourist seasons, such as cherry blossom season, can lead to booked-out accommodations, so reserve early.

Book flights
Compare and purchase flight tickets
When planning your trip to Japan, it's advisable to start by researching flights several months in advance. Airlines often release promotional fares, especially during off-peak seasons. Use comparison sites like Skyscanner or KAYAK to get a sense of the price range. Be flexible with your travel dates if possible; flying mid-week might be cheaper than on weekends.

Order Japan Rail Passes for each family member
Purchase your Japan Rail Pass before departure
The Japan Rail (JR) Pass offers unlimited travel on JR trains, making it a cost-effective option for tourists. However, it's only available to foreign tourists and must be purchased *before* you arrive in Japan. Determine the areas you plan to visit; if you're traveling extensively, a nationwide pass is beneficial, but if you're only exploring a specific region, consider regional JR passes. Children under 12 get a discounted pass, so ensure you order the correct type for each family member.

Plan your attire for Japan
Check the weather at your destination on this site
Japanese weather varies significantly by season. In summer, it's hot and humid, so breathable clothes are essential. Winters, especially in the north, can be cold, requiring warm attire. If visiting during the rainy season (June to early July), pack a good umbrella and waterproof shoes. While Japan is generally casual, certain places like temples, shrines, or upscale restaurants may require modest and neat dressing.
Reserve a pocket Wi-Fi or SIM card
SIM card or pocket Wi-Fi is required
Beyond clothes, consider packing essentials like a universal power adapter (Japan uses Type A and B sockets), portable Wi-Fi or SIM card for internet access, and any necessary medications (with a copy of the prescription).
Which is better: a SIM card or pocket Wi-Fi?
When traveling in Japan, one essential to consider is securing internet access, especially given that many locations still don't offer free Wi-Fi. To ensure you can use your smartphone throughout your trip, you'll typically have three options: (1) a SIM card, (2) pocket Wi-Fi, or (3) the roaming service provided by your mobile company. Roaming services can be quite expensive, so we often recommend using a SIM card or pocket Wi-Fi. While SIM cards tend to be more affordable than pocket Wi-Fi, they can be trickier to set up. Pocket Wi-Fi, on the other hand, can be shared among several users, making it a favorable choice for families or groups.
▼SIM card
Advantages:
Relatively affordable.
Disadvantages:
Can be time-consuming to set up initially.
May have strict data limits.
▼Pocket Wi-Fi
Advantages:
Offers substantial data allowances.
A single device can be shared among multiple users.
Easily usable with PCs as well.
Disadvantages:
Typically more expensive.
