Japan has an unusually rich domestic market for scheduling tools. Alongside global names like Calendly, local products such as TimeRex, Spir, and Jicoo serve millions of users with Japanese-first interfaces and business customs baked in. If you work with Japanese clients or teams, knowing this landscape helps.
This article compares the major options from the perspective of individuals, freelancers, and small teams. It is published on Chronock’s own blog, so fairness matters: we include each tool’s genuine strengths, based on official pages.
The information below is current as of July 10, 2026. Pricing and features may have changed since, so always check each service’s latest pages before deciding.
Three types of scheduling tools
Before comparing, it helps to separate three categories:
- Booking-page (link) tools: you publish your availability and invitees pick a time — Calendly, TimeRex, Chronock, and most tools here.
- Poll tools: an organizer proposes dates and participants vote — Chouseisan is the Japanese classic. Usually no calendar integration.
- Built-in calendar features: Google Calendar’s appointment schedules, covered in detail in a separate article.
For business one-on-ones and small-group scheduling, booking-page tools are the main category.

Where each tool stands
Chronock — one tool for Google Calendar-centric work
Chronock supports Google Calendar and Microsoft Outlook calendars (Microsoft 365 work or school accounts), with Google Calendar as its most mature integration. Availability detection across multiple calendars and one one-way, busy-only calendar sync rule are included for free, and Pro adds candidate-time text with provisional holds, multiple sync rules with two-way and title/description sync — including Google↔Google, Outlook↔Outlook, and cross-provider Google↔Outlook — and booking history with contacts. It suits people who juggle work, personal, and side-business calendars and want scheduling and double-booking prevention in one place. Chronock’s Outlook integration works with Microsoft 365 work or school accounts. Personal Microsoft accounts (such as Outlook.com) are not supported due to Microsoft API limitations. If you need iCloud or a personal Microsoft account today, or poll-style scheduling, other tools below fit better.
TimeRex — the generous Japanese standard
TimeRex, run by MIXTEND (the company behind Chouseisan), passed 500,000 registered users in 2026. Its free plan is remarkably broad: unlimited schedulings, group polls, video conferencing links, and even Zapier/webhooks. Calendar connections cap at two per account. See our detailed TimeRex vs Chronock comparison.
Spir — scheduling-type variety and team features
Spir stands out for scheduling types: polls, manual candidates, group choice, and a three-party trial. Multiple calendar connections and candidate-time text export are free. Its September 2025 plan revision introduced per-seat billing and moved embeds and webhooks to the Team plan. See our Spir vs Chronock comparison.
Jicoo — the broad feature set
Jicoo covers scheduling plus payments, forms, and seminar bookings, with calendar support spanning Google, Microsoft, and iCloud. Unlimited booking pages even on the free plan. The breadth is a strength for complex use; for simple needs, evaluate whether you will use it.
bookrun — simple and side-business friendly
bookrun comes from Basic Inc. (known for formrun). Free unlimited schedulings and a ¥790/month entry price make it an easy start for individuals and side businesses.
Nitte — pivoting toward HR and recruiting
Nitte offers a low-priced Pro plan (¥440/month) and increasingly targets HR/recruiting scheduling. The official site announces a relaunch as Nitte.AI (beta pre-registration), so check the product’s direction before committing.
Aitemasu — mobile-first and free-centric
Aitemasu is built around its mobile app, with core features nearly unrestricted for free. A good fit for individuals who want Google Calendar-based candidate proposals from their phone.
eeasy — corporate inter-company scheduling
eeasy targets corporate sales and recruiting teams coordinating across companies. Its pricing is unusual: free for individuals, and corporate billing applies only to users who schedule six or more times a month. Likely more than individuals and small teams need.
Calendly — the global standard
Calendly remains the global reference: Outlook and Exchange support, round-robin, Salesforce/HubSpot/Marketo integrations, and payments. Note that its native booking-page translations do not include Japanese, which matters for Japanese-first teams. See our Calendly vs Chronock comparison.
Chouseisan — the poll classic (different job)
Chouseisan is Japan’s beloved free date-poll tool for parties and group events. It has no calendar integration or booking pages; for automating business scheduling, the booking-page tools above are the relevant category.
Choosing by situation
| Situation | Consider |
|---|---|
| Unlimited free schedulings | TimeRex, bookrun, Aitemasu |
| Availability across multiple Google Calendars | Chronock, Jicoo |
| Calendar-to-calendar sync against double bookings | Chronock (one rule on Free, more on Pro) |
| Outlook (Microsoft 365) calendars | Chronock, Jicoo, Calendly, TimeRex, Spir |
| iCloud calendars | Jicoo |
| Poll-style group scheduling | Chouseisan (free), TimeRex, Spir |
| Candidate times as email text | Chronock, Spir |
| Payments or seminar bookings | Jicoo, Calendly |
| Corporate inter-company scheduling at scale | eeasy, Calendly |
| Checking if Google Calendar’s built-in feature suffices | Appointment schedules free-tier guide |
Bottom line
There is no single best scheduling tool — only the best match for how you schedule.
- For free-plan breadth, TimeRex and bookrun lead.
- For scheduling-type variety, Spir; for feature breadth, Jicoo and Calendly.
- For corporate inter-company scheduling, eeasy.
- And if you run life across several Google Calendars and want booking pages, candidate times, calendar sync, and post-booking history in one affordable tool, Chronock is built for exactly that.
Every service here offers a free plan or trial. The most reliable test is running one or two real scheduling conversations through your shortlist before deciding.
