TWICE’s currently verifiable paid fanclub choice is clearest in Japan. The official service lists an annual ONCE JAPAN plan, a monthly ONCE JAPAN MOBILE plan and W Member status for fans who hold both. They are different products, and none of them guarantees a ticket.

This guide does not announce a new global ONCE generation, concert, fan meeting or ticket sale. It answers the narrower 2026 decision: which active Japan membership route exists, what each plan includes, and what an overseas fan must verify before paying.

The three choices at a glance

Choice Current official price Main difference
ONCE JAPAN ¥6,160 for a new membership; ¥5,280 to renew Annual service, membership card and joining benefit, planned twice-yearly magazine
ONCE JAPAN MOBILE ¥440 per month Smartphone-only monthly service with separate digital content
W Member Cost of holding both services Extra W-only access; both plans must use one Plus member ID

The official comparison page says both paid services may offer ticket priority applications, but it also states that tickets are not guaranteed, priority can vary and some performances may be excluded.

ONCE JAPAN is the annual plan

ONCE JAPAN is the full annual Japan fanclub service. Its official page lists a physical membership card and joining benefit for new members, member-only goods, digital content and a fanclub magazine planned twice per year.

The site was still publishing membership-card, joining-benefit and renewal-shipment notices in July 2026, which confirms that the service is active. That does not mean a particular benefit or ticket window is open for every buyer; the current notice controls.

International fans should check whether the registration form accepts their address and payment method before paying. A Japan membership should not be presented as a universal global membership.

ONCE JAPAN MOBILE is a separate monthly service

ONCE JAPAN MOBILE costs ¥440 per month and is designed for smartphones. Its listed benefits include ticket priority applications, gallery, videos, wallpapers, Q&A, games, an app and birthday mail.

The annual and mobile sites carry different content. Paying for the annual plan does not automatically create a mobile subscription, and paying monthly does not create the annual membership card or joining benefit.

W Member requires both plans on one ID

W Member is not a third standalone subscription. It is the status given to someone registered for both ONCE JAPAN and ONCE JAPAN MOBILE. The official W Member page says the same Plus member ID must be used; if the IDs differ, they must be consolidated.

W status can add W-only ticket applications and special content, but the official page repeats that ticket supply is not guaranteed and that some events may be excluded. Do not buy both plans solely because a resale seller promises access.

What to check before joining

  • Confirm that you are on oncejapan.com, sp.twicejapan.com or the official linked Plus member login.
  • Compare annual versus monthly cost and the content you will actually use.
  • Use the same Plus member ID if W Member status matters.
  • Check address, payment and shipping support for your country.
  • Read the separate event notice for eligibility, identity matching and application dates.
  • Treat membership, merchandise and tickets as separate transactions.

Why this guide is Japan-specific rather than global

Readers searching for “TWICE official fandom” broadly will find a lot of discussion of ONCE as a global fandom identity, separate from any paid product — the name predates and exists independently of any membership tier. What this guide covers is narrower and more concrete: the specific, currently verifiable paid services sold through Japan’s official TWICE channels. That narrower scope is deliberate. A global ONCE membership tier, if one exists or is announced outside Japan, would need its own separate official notice with its own separate terms; nothing in the sources checked here describes a worldwide equivalent to ONCE JAPAN, and this guide does not assume one exists just because a Japan-specific version does.

Frequently asked

Is ONCE a paid membership everywhere, or just in Japan? Based on the sources checked here, only the Japan services described above are confirmed paid membership products with stated fees. Treat any claim about a paid global ONCE tier as something to verify against its own official notice rather than assuming it mirrors the Japan structure.

Does paying for ONCE JAPAN or the mobile plan guarantee a ticket to a specific tour stop? No. The official comparison page explicitly states tickets are not guaranteed even for paid members, and that priority access can vary by show and may exclude certain performances entirely.

If I already have ONCE JAPAN, is upgrading to W Member worth it just for the extra content? That depends entirely on how much you value the W-only access described on the official W Member page relative to its added cost — this guide does not make that value judgment for you, since “worth it” depends on how much of the existing free and paid content you already use.

The safe 2026 answer is simple: ONCE JAPAN is the annual Japan service, ONCE JAPAN MOBILE is the monthly smartphone service, and W Member requires both. Join only through the official pages and never assume that membership alone creates a confirmed event or guaranteed ticket.
