SOKUYAKU Now Supports Rakuten ID Login and Registration, Starts Offering Rakuten Points. Accelerating New Member Acquisition Through Rakuten Partnership

J Frontier Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; President and CEO: Atsuhiro Nakamura; hereinafter 'the Company') announces that it has implemented a login and membership registration function using Rakuten ID in its online medical consultation and medication guidance app 'SOKUYAKU' in partnership with Rakuten Group, Inc. (hereinafter 'Rakuten'). This allows Rakuten members to register and log in to SOKUYAKU more smoothly.

Furthermore, users who log in or register with Rakuten ID will receive 'Rakuten Points' for new membership registration to SOKUYAKU and for subscribing to the paid membership service 'SOKUYAKU Premium'.

Additionally, a campaign will be held from Tuesday, September 29, 2026 to Monday, November 30, 2026, offering double the usual amount of 'Rakuten Points'.

By linking with Rakuten's member base, we aim to create an environment where online medical consultations are more accessible, while also expanding new member acquisition and continued use of SOKUYAKU.

Further Strengthening the Partnership with Rakuten, Making SOKUYAKU a More Accessible Medical Service

The Company and Rakuten have signed a basic agreement for a comprehensive business partnership aimed at promoting the adoption of online medical consultations and online medication guidance, and are advancing initiatives that leverage both companies' services and member bases.

In previous collaborations, we have worked to improve convenience from online consultation to medication guidance and prescription drug receipt, such as expanding the methods for receiving prescription drugs when selecting 'Yoyaku Souri Pharmacy' operated by Rakuten from SOKUYAKU.

Now, we have taken this initiative further by implementing the Rakuten ID login and membership registration function for SOKUYAKU, which was previously planned as a future development.

By utilizing Rakuten ID, we reduce the burden on Rakuten members to set up and manage new IDs and passwords, creating an environment where SOKUYAKU can be used more smoothly.

Rakuten ID Enables Login and Membership Registration for SOKUYAKU

With this partnership, Rakuten members can now register and log in to SOKUYAKU using their Rakuten ID.

By improving the convenience of membership registration and login when using online medical consultations, we provide a new opportunity for Rakuten members who have never used SOKUYAKU to try online medical consultations.

The Company aims to strengthen the path from awareness expansion to new member acquisition and service usage by leveraging contact points with Rakuten's extensive member base, and to further promote the adoption of online medical consultations and medication guidance.

Accelerating SOKUYAKU Member Acquisition Through Rakuten's Member Base

This Rakuten ID integration is positioned as an initiative to further expand SOKUYAKU's member base, in addition to improving user convenience.

By combining smooth membership registration and login via Rakuten ID with the offering of 'Rakuten Points', we strengthen the usage path:

Creating new touchpoints with Rakuten members → Membership registration for SOKUYAKU → Use of online medical consultations → Subscription and continued use of SOKUYAKU Premium

The Company will continue to enhance user convenience through the partnership with Rakuten, promote new member acquisition and continued use, and drive further business growth for SOKUYAKU.

Furthermore, by expanding the network with medical institutions, pharmacies, and partnerships with external services, we aim to establish online medical consultations and medication guidance as more familiar options and promote the further adoption of healthcare DX.

[What is SOKUYAKU?]

'SOKUYAKU' is an online medical service that allows users to complete consultations, medication guidance, and medication receipt from home or work using smartphones or tablets.

After an online consultation with a doctor, an online medication guidance session with a pharmacist is conducted, and then prescription drugs can be delivered to home or picked up at a nearby pharmacy. Same-day medication receipt is also supported.
