KDDI Expands Japan SIM Lineup for International Visitors to Enhance Travel Experience

KDDI Enhances Japan SIM Services for Foreign Tourists

In an exciting move to improve connectivity for international travelers, KDDI is expanding its lineup of data-only eSIMs, known as "Japan SIM," specifically tailored for foreign visitors. The updated offerings will go live on March 25, 2026, and aim to ensure a seamless online experience for tourists arriving in Japan.

The new plans introduced include two unlimited data options: "Unlimited Data (5 Days)" and "Unlimited Data (7 Days)." These services are designed to cater to long-term stay tourists, making it much easier for them to access necessary data services at any stage of their journey.

Moreover, KDDI is introducing a promotional code mechanism. This feature allows customers to activate their selected data plans when they deem necessary, providing flexibility and convenience during their stay in Japan.

The special aspect of the Japan SIM service lies in its accessibility. Travelers can apply for a data plan online from their home country before arriving in Japan. Following a straightforward setup, users can download the eSIM profile to their devices, enabling them to connect to the povo2.0 network as soon as they land in the country.

KDDI aims to ensure that every traveler enjoys a rich and comfortable experience while exploring Japan. The comprehensive lineup of the new Japan SIM plans is as follows:

Plan Name	Price (Tax Included)	Activation Timing
------	----	--------
3GB (3 Days)	¥600	Immediate upon purchase
5GB (5 Days)	¥900	Immediate upon purchase
10GB (7 Days)	¥1,430	Immediate upon purchase
20GB (30 Days)	¥2,700	Immediate upon purchase

In addition to these plans, several unlimited data options are also being introduced:

Plan Name	Price	Activation Timing
-------	----	--------
Unlimited Data (6 hours) + 0.5GB (60 Days)	¥260	Promo code sent upon purchase
Unlimited Data (3 Days) + 0.5GB (60 Days)	¥1,540	Promo code sent upon purchase
Unlimited Data (5 Days) + 0.5GB (60 Days)	¥2,510	Promo code sent upon purchase
Unlimited Data (7 Days) + 0.5GB (60 Days)	¥3,390	Promo code sent upon purchase

*Note: 0.5GB (60 Days) is applicable immediately upon purchase.

However, KDDI will discontinue certain plans, including the 1GB (3 Days) and various unlimited data options by March 25, 2026, at 9:30 AM. Travelers should keep this deadline in mind when planning their data needs.

Additionally, KDDI is running a registration campaign that offers new users a free "Unlimited Data (24 Hours)" service when they enter a promo code after registering. This campaign runs from August 28, 2025, until an undetermined end date, with further notifications provided on the KDDI website.

To navigate the Japan SIM purchasing process, travelers are encouraged to refer to the detailed instructions available online. KDDI is committed to creating a hassle-free and enriching experience for every international visitor in Japan.

As KDDI enhances its offerings, tourists can look forward to improved connectivity, helping them stay connected and share their Japanese adventures with loved ones back home more effortlessly than ever.
