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.

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.

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.

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.

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.

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
Relatively affordable.
Can be time-consuming to set up initially.
May have strict data limits.
▼Pocket Wi-Fi
Offers substantial data allowances.
A single device can be shared among multiple users.
Easily usable with PCs as well.
Typically more expensive.
