LINE Official Account Free vs Premium 2026: Choosing the Right Plan for Chatbot Integration

# LINE Official Account Free vs Premium 2026: Choosing the Right Plan for Chatbot Integration

If you are setting up a LINE Official Account for your business in Japan and feeling confused about which plan to choose, you are not alone. The three-tier structure — Communication (Free), Light, and Standard — raises immediate questions: Is the free plan good enough to start? When does it make sense to pay ¥5,000 or ¥15,000 per month? And how do chatbot integrations fit into each tier?

This guide gives you a clear, honest breakdown of every plan, what chatbot connectivity looks like on each, and a practical recommendation framework so you can pick the right option for your business stage.

The Three LINE Official Account Plans at a Glance

LINE for Business (LY Corporation) offers exactly three subscription tiers for LINE Official Accounts in Japan. Understanding the core structure is the starting point.

Note on message counting: LINE counts one "message" as one send to one friend. If you send a broadcast to 1,000 friends, that consumes 1,000 messages from your monthly quota — regardless of how many chat bubbles are in that single broadcast (up to 3 bubbles per send is standard).

Communication Plan (Free) — What You Actually Get

The Communication Plan is LINE's entry-level tier, priced at ¥0 per month. The 200-message monthly cap sounds extremely limited, and it is — by design. LINE positions this tier for businesses that want to explore the platform before committing budget.

Key constraints:

• Hard cap at 200 messages per month with no option to purchase extras
• Full access to LINE's messaging features within that cap
• Messaging API access is available (you can connect chatbot tools)
• No verified badge on the Free plan alone (badge requires a separate screening process)

For a business with a modest, highly segmented audience — say, a boutique with 150 LINE friends who sends one curated message per month — the Free plan is genuinely usable. For most businesses that want consistent customer communication, 200 messages is a ceiling you will hit quickly.

Light Plan (¥5,000/month) — The Practical First Upgrade

At ¥5,000 per month (excluding tax), the Light Plan lifts the monthly ceiling to 5,000 messages. This covers a business with up to 5,000 LINE friends sending one broadcast per month, or 1,000 friends receiving five messages per month.

Key constraints:

• 5,000 messages per month — still a hard cap, no add-ons available
• Full feature access including chat labels, rich menus, and LINE VOOM
• Messaging API available for chatbot and automation integrations
• Suitable for local businesses, service shops, and early-stage e-commerce

The Light Plan is the most popular starting point for Japanese SMBs (中小企業) that have already built a meaningful LINE friends list and need reliable monthly outreach. The absence of additional message purchases means you need to plan your list size carefully.

Standard Plan (¥15,000/month) — Full-Scale Operations

The Standard Plan at ¥15,000 per month includes 30,000 messages and is the only tier that allows you to purchase additional messages beyond the included quota.

Current additional message rates (as of 2026):

• Up to 200,000 messages/month: ¥3 per message
• Beyond 200,000 messages/month: ¥2.50 per message

Important for 2026: LY Corporation has announced a pricing structure change effective October 1, 2026, moving from the previous multi-tier graduated rate to a simplified two-tier rate. If your current strategy relies on sending large volumes and benefiting from the old stepped discounts, review the impact before October.

Standard Plan is best for:

• Businesses with 5,000+ LINE friends
• E-commerce stores running promotional campaigns with broad reach
• Service businesses with automated reminder and follow-up sequences
• Any deployment where an AI chatbot handles inbound conversations at scale

The Verified Badge: What It Is and Which Plans Can Get It

The LINE verified badge is a blue checkmark displayed next to an account name, signaling to users that LINE has confirmed the account belongs to a legitimate business. There is also a gray badge for accounts that have applied but not yet been verified.

The badge is not tied to a specific pricing plan — it is the result of a separate screening process conducted by LY Corporation. Requirements include:

• Submitting a company profile, website URL, and business license documentation
• Passing LY Corporation's review (typically 5–10 business days)
• Having a valid LINE Official Account on any plan

However, invoice payment (rather than credit card) is only available to verified accounts. For larger businesses that require invoice-based billing, verification is a practical prerequisite.

Practical impact on chatbot use: The verified badge does not unlock additional API features. Chatbot integration works identically on verified and unverified accounts.

Chatbot Integration: How Each Plan Affects Your Options

This is the question most businesses researching this topic actually need answered. Let's be direct.

Messaging API Access Across All Plans

LINE's Messaging API — the connection layer that chatbot platforms use to send, receive, and automate messages — is available on all three plans at no additional cost. The API itself is free; you only pay for the messages consumed under your plan tier.

This means:

• You can integrate a chatbot on the Free plan (within the 200-message cap)
• You can integrate a chatbot on the Light plan (within the 5,000-message cap)
• The Standard plan's unlimited additional messages make it the natural home for any chatbot deployment at scale

Where Plan Limits Create Real Friction for Chatbots

A chatbot does not just send outbound broadcasts — it responds to every inbound user message with at least one reply. In an active customer service chatbot deployment, inbound message volume from users can be significant.

Example scenario — Free Plan:

You launch a chatbot on the Free plan. In the first two weeks, 150 users message your account. Each conversation averages 3 chatbot replies. That is 450 outbound messages — and you have already hit your 200-message monthly cap halfway through your usage.

Example scenario — Light Plan:

You have 800 LINE friends. You run one monthly broadcast (800 messages). Your chatbot handles 200 support inquiries, each generating an average of 2 replies (400 messages). Total: 1,200 messages — comfortably within the 5,000 cap.

Example scenario — Standard Plan:

You have 8,000 LINE friends. Monthly broadcast (8,000 messages). Chatbot handles 1,500 support conversations with an average 3-reply depth (4,500 messages). Total: 12,500 messages — within the 30,000 included quota, with headroom for campaigns.

When to Upgrade: A Practical Decision Framework

Upgrade from Free to Light when:

• Your LINE friends list exceeds 150–200 people
• You want to send at least one monthly broadcast
• You are integrating a chatbot for any real-volume customer service

Upgrade from Light to Standard when:

• Your LINE friends list exceeds 3,000–4,000 people (approaching the cap with regular broadcasts)
• Your chatbot handles more than 200–300 conversations per month
• You are running promotional campaigns requiring multiple touch points per customer
• You need invoice payment (requires verified account, which aligns well with Standard plan operations)

Stay on Light if:

• You have a tightly managed audience under 5,000 friends
• Your chatbot use is limited to simple FAQ responses for a low-traffic service
• You are not yet running frequent broadcast campaigns

Chatbot Integration with LINE Official Account: What to Know Before You Build

Connecting a chatbot to LINE OA requires going through the Messaging API. Here is what that integration path looks like in practical terms.

Technical Prerequisites

1. A LINE Official Account on any plan
2. A Messaging API channel linked to your account (set up via LINE Developers Console — free)
3. A chatbot platform or development resource to handle webhook events

Build vs. Buy

Most Japanese businesses — especially 中小企業 without dedicated IT teams — choose a third-party chatbot platform rather than building from scratch. Native LINE chatbot tools offer basic keyword-response functionality, but for AI-powered, context-aware conversation, a dedicated platform is necessary.

RAG-Based AI Chatbots and LINE OA

Standard keyword-based chatbots handle scripted flows well but break down when customers ask questions outside the script. RAG (Retrieval-Augmented Generation) chatbots — like OneBot — pull answers from your actual business documents (product manuals, FAQ databases, policy pages) in real time, which keeps hallucinations to a minimum without sacrificing answer breadth.

This matters for LINE OA deployments because:

• Japanese customers expect precise, accurate answers — approximate responses damage trust
• A chatbot that fails to answer correctly escalates to human agents, defeating the cost-reduction goal
• RAG architecture makes the chatbot genuinely useful on day one, without months of manual training

For a deeper look at why RAG matters for business chatbots, see: LINE Chatbot Business Guide 2026.

OneBot + LINE Official Account: Compatible with All Plans

OneBot integrates natively with LINE Official Account through the Messaging API and works on all three plan tiers. Because OneBot manages the conversation logic, your LINE OA plan selection comes down purely to your message volume requirements — the chatbot functionality itself is not plan-dependent.

Key things to know about OneBot's LINE integration:

• Native LINE OA integration — no middleware or manual webhook setup required
• RAG technology keeps hallucinations to a minimum by grounding responses in your actual business data
• Data residency — all data processed on domestic infrastructure at our Tokyo data center (国内データセンター（東京）), fully APPI-compliant
• 2-week deployment — no IT team required on your side
• Automates up to 60% of CS inquiries — measurable load reduction from the first month

We typically recommend starting on the Standard Plan for any serious chatbot deployment, because the message cap on Free and Light plans constrains the chatbot's ability to handle realistic inquiry volumes. That said, running a proof-of-concept on the Light Plan for the first month is a valid way to measure actual message consumption before committing to the full Standard spend.

Summary: Which Plan Should You Choose?

The LINE Official Account plan you choose sets the ceiling on your chatbot's message throughput. For any deployment where the chatbot is expected to handle real customer inquiries at meaningful volume, the Standard Plan is the correct starting point — the ¥15,000 monthly fee is quickly offset by the CS cost savings an AI chatbot delivers.

Ready to See What an AI Chatbot Looks Like on Your LINE Official Account?

OneBot integrates directly with LINE Official Account and can be deployed in two weeks, with no IT team required. Our RAG-based AI handles up to 60% of customer service inquiries automatically, and all data stays on domestic infrastructure in Tokyo (国内データセンター（東京）) for full APPI compliance.
