monday.com or Asana: which should you choose?monday.com と Asana、どちらを選ぶべきですか
Japan pricing, annual billing, excluding tax. If you are buying from Japan, the benchmark is Asana Starter. At the same seat count the yen-priced Asana is cheaper, by ¥140,000 a year at 20 seats. The reason to pick monday.com is not price; it is whether you want to design the fields you track yourself.
The currencies are not even the same
Asana’s Japanese pricing page is in yen, and Starter is ¥1,200 a month for 1 user on annual billing. monday.com shows US dollars even on its Japanese page, and Standard is $12 a month for 1 seat (we could not find a yen price stated on the vendor’s own pages). At $1 = ¥150, 20 seats is ¥288,000 a year against $2,880 a year, a gap of roughly ¥140,000. The two only meet at $1 = ¥100, and the weaker the yen, the more expensive monday.com becomes.
Both are quoted excluding tax. monday.com writes that its prices do not include tax and that tax is set by the billing country, while Asana states that a purchase for business use is subject to Japanese consumption tax (JCT) when the billing address is in Japan. At 20 seats on annual billing, what leaves the account is not ¥288,000 but ¥316,800 including tax.
Seats are not sold 1 at a time
A seat is the right for 1 person to log in to the admin console, and seats are not sold 1 at a time. monday.com starts at a minimum of 3 seats and sells only in seat groups (the vendor’s own example is 5 seats for 4 people). Asana offers 2, 3, 4 and 5 seats, and moves in steps of 5 above that. Whether you are 1 person or 2, monday.com means 3 seats ($9 × 3 × 12 = $324), and Asana starts at 2 seats (¥1,200 × 2 × 12 = ¥28,800).
For 21 people and above, one monday.com support article says "3, 5, 10, 15, 20, 30 seats etc." while another says the plans start at a minimum of 3 seats and then ascend in multiples of 5, so we could not find it stated on the vendor’s own pages whether 25 seats can be selected. Under either wording, 4 seats and 9 seats are not available.
Both are free for up to 2 people. monday.com Free stops at 3 boards and 200 items, while Asana Personal has no limit on tasks or projects. We could not find it stated on either vendor’s own pages what happens to your data when you move from a paid plan back to free.
Seats billed against actual headcount (paid plans, monday.com / Asana)
Figures are given as monday.com / Asana. Headcounts of 21 and above are not shown, because we could not confirm monday.com’s seat increments on the vendor’s own pages. Sources: support.monday.com (minimum of 3 seats, sold in seat groups), help.asana.com (2, 3, 4 and 5 seats, then steps of 5). Checked August 2026.
At 3, 6, 11 and 20 people, how much leaves the account?
| People actually using it | Seats billed (monday / Asana) | monday.com Standard, annual billing, amount paid upfront (excluding tax, US dollars) | Asana Starter, annual billing, amount paid upfront (excluding tax, yen / including 10% tax) | How to read this figure |
|---|---|---|---|---|
| 3 people | 3 seats / 3 seats | $432 (about ¥64,800) | ¥43,200 / ¥47,520 | The seats are filled and you pay the list price |
| 4 people | 5 seats / 4 seats | $720 (about ¥108,000) | ¥57,600 / ¥63,360 | Only monday.com wastes 1 seat |
| 6 people | 10 seats / 10 seats | $1,440 (about ¥216,000) | ¥144,000 / ¥158,400 | Both vendors throw away 4 seats |
| 11 people | 15 seats / 15 seats | $2,160 (about ¥324,000) | ¥216,000 / ¥237,600 | As above |
| 20 people | 20 seats / 20 seats | $2,880 (about ¥432,000) | ¥288,000 / ¥316,800 | The seats are filled, and the gap is ¥140,000 a year |
Sources: https://asana.com/ja/pricing / https://monday.com/lang/ja/pricing (checked August 2026). All figures are annual billing and are quoted excluding tax. The tax-inclusive Asana column is a reference calculation at Japan’s 10% consumption tax (the statutory standard rate as of August 2026); the rate is not stated by Asana. Yen conversions assume $1 = ¥150 and are indicative.
The formula is the monthly price for 1 seat × seats billed × 12 months. At 6 people both vendors bill 10 seats, so for 1 person it comes to $1,440 ÷ 6 ÷ 12 = $20.00 and ¥144,000 ÷ 6 ÷ 12 = ¥2,000, which is 1.67 times the list price. On monthly billing Asana is ¥1,475 a month for 1 user (1.23 times the annual rate). We could not determine monday.com’s monthly price for 1 seat from its pricing page. Working back from the vendor’s "annual billing saves 18% over monthly", Standard comes to $12 ÷ 0.82 = about $14.6. Check the actual amount on the sign-up screen.
What can you not do on the cheapest paid plan?
An automation rule is a mechanism that runs by itself once you set a condition and an action (for example, emailing the manager on completion); an integration exchanges data automatically with Gmail or Slack; a timeline is a view that lays out work periods as horizontal bars.
| Feature | monday.com Basic (annual billing, $9 per seat, excluding tax) | Asana Starter (annual billing, ¥1,200 per user, excluding tax) |
|---|---|---|
| Automation rules | Not on Basic; the pricing page lists it from Standard up (250 actions a month) | Unlimited rules |
| Third-party integrations | As above | Yes (over 100 free integrations) |
| Timeline and Gantt chart | No | Yes |
| Calendar view | No | Yes (from Personal upwards) |

The annual cost of 3 seats is $324 against ¥43,200 (¥47,520 including tax), which is practically level, so what that small gap buys you is these 4 features. If you want automation on monday.com, that means Standard ($432 a year).
Who should not choose these?
monday.com is a poor fit for a team of exactly 4 people, and for 1 or 2 people who want a paid contract. You pay for 1 seat, or 3 seats, that nobody uses.
Asana is a poor fit for a team of 3 to 5 people that uses neither automations nor integrations nor timelines, for anyone who wants to design their own fields and run it like a ledger, and for anyone who needs portfolios but cannot stretch to Advanced.
So which should you choose?
- Up to 2 people — Both are free. Decide once you hit the limits of monday.com Free.
- 1 or 2 people who need paid features — Asana Starter. You can buy from 2 seats, at ¥28,800 a year (¥31,680 including tax).
- 3 to 5 people who use neither automations nor integrations nor timelines — monday.com Basic. $324 a year for 3 seats, $540 for 5.
- 3 to 5 people who need automations or timelines — Asana Starter. monday.com moves you up to Standard.
- Exactly 4 people — Asana Starter. You can buy exactly 4 seats; monday.com bills 5.
- 6 to 20 people whose work crosses departments — Asana Starter. 1 task can sit in several projects.
- 6 to 20 people who want to design their own fields — monday.com Standard. $2,880 a year for 20 seats. It costs ¥140,000 more, but you can line up columns and build a ledger.
- 21 people and above — We could not confirm the seat increments. Please check the seat counts offered on the sign-up screen.
- If you cannot decide — Asana Starter. It is cheaper in yen, its seat increments are finer, and automations and timelines are both in the cheapest plan.

Asana amounts are the yen prices on its Japanese pricing page (excluding tax); monday.com amounts are in US dollars even on its Japanese page (excluding tax). Annual billing is quoted as a monthly price for 1 seat, so we multiply by 12, and yen conversions are shown as indicative figures assuming $1 = ¥150.

日本から契約するなら基準は Asana Starter です。同じ席数なら円建ての Asana が安く、20席で年14万円の差。monday.com を選ぶ理由は価格ではなく、管理項目を自分で設計したいかです。
通貨からして違います
Asana の日本語料金ページは円建てで、Starter は年払1ユーザー月¥1,200。monday.com は日本語ページでも米ドル表示で、スタンダードは1席月$12です（円建て価格は公式に記載を確認できませんでした）。1ドル150円なら20席で年¥288,000 対 年$2,880、差はおよそ14万円。両社が並ぶのは1ドル100円で、円安ほど monday.com は高くなります。
表示はどちらも税別。monday.com は価格に税金を含まず請求国で決まると書き、Asana は請求先が日本国内なら事業上の購入に消費税（JCT）が課税されると明記します。20席・年払で出ていくのは¥288,000ではなく税込¥316,800です。
席は1つずつ買えません
席（シート）は管理画面にログインできる人1人分の権利で、1席単位では買えません。monday.com は最低3席で、席のグループ単位でしか買えません（公式は4人なら5席の例）。Asana は2・3・4・5席があり、以降は5刻みです。1人でも2人でも monday.com は3席分（$9 × 3 × 12 = $324）、Asana は2席から（¥1,200 × 2 × 12 = ¥28,800）です。
21人以上は、monday.com のサポート記事が「3, 5, 10, 15, 20, 30席など」と書く一方、別の記事は「最低3席、以降は5の倍数」と書いており、25席を選べるかどうかは公式に記載を確認できませんでした。どちらの記載でも4席・9席は選べません。
無料は両社2人まで。monday.com Free はボード3つ・200アイテムで止まり、Asana Personal はタスクもプロジェクトも無制限です。有料から無料に戻したときのデータの扱いは、両社とも公式に記載を確認できませんでした。

3人・6人・11人・20人で、いくら出ていきますか

|---|---|---|---|---|
| 3人 | 3席／3席 | $432（約64,800円） | ¥43,200／¥47,520 | 席が埋まり、表示価格どおり |
| 4人 | 5席／4席 | $720（約108,000円） | ¥57,600／¥63,360 | monday.com だけ1席が無駄になる |
| 6人 | 10席／10席 | $1,440（約216,000円） | ¥144,000／¥158,400 | 両社とも4席分を捨てている |

出典：https://asana.com/ja/pricing ／ https://monday.com/lang/ja/pricing （2026年8月確認）。すべて年払・表示は税別。Asana の税込は日本の消費税10%（2026年8月時点の法定標準税率）で計算した参考値で、税率は Asana の公式記載ではありません。円換算は1ドル150円と仮定した目安です。
計算式は 1席あたり月額 × 請求席数 × 12か月。6人は両社とも10席分なので、1人あたり $1,440 ÷ 6 ÷ 12 = $20.00、¥144,000 ÷ 6 ÷ 12 = ¥2,000 と表示価格の1.67倍です。月払は Asana が1ユーザー月¥1,475（年払の1.23倍）。monday.com の月払1席単価は公式ページで確定できませんでした。公式の「年払は月払より18%お得」から逆算すると Standard は $12 ÷ 0.82 = 約$14.6。実額は申し込み画面で確認してください。
有料の最下位プランで、何ができませんか
自動化ルールは条件と動作を決めると自動実行される仕掛け（例：完了で上長にメール）、連携は Gmail や Slack と自動でデータをやりとりする機能、タイムラインは作業期間を横棒で並べる画面です。

3席の年額は $324 対 ¥43,200（税込¥47,520） とほぼ並び、この差で4機能の有無が決まります。monday.com で自動化を使うなら Standard（年$432）です。
選ぶべきでないのは、どんな人ですか
monday.com が向かないのは、実人数4人と、1〜2人で有料契約したい人です。1席分か3席分を余分に払います。
Asana が向かないのは、3〜5人で自動化も連携もタイムラインも使わないチーム、管理項目を自分で設計して台帳のように使いたい人、ポートフォリオが要るのに Advanced を出せない人です。
結局、どちらを選ぶか
- 2人まで ── 両方とも無料。monday.com Free の上限に当たってから決めてください。
- 1〜2人で有料機能が要る ── Asana Starter。2席から買え、年¥28,800（税込¥31,680）。
- 3〜5人で自動化も連携もタイムラインも使わない ── monday.com Basic。3席で年$324、5席で$540。
- 3〜5人で自動化かタイムラインが要る ── Asana Starter。monday.com は Standard に上がります。
- ちょうど4人 ── Asana Starter。4席ちょうどで買え、monday.com は5席分です。
- 6〜20人で同じ仕事が部門をまたぐ ── Asana Starter。1つのタスクを複数プロジェクトに置けます。
- 6〜20人で管理項目を自分で設計したい ── monday.com Standard。20席で年$2,880。14万円高くても列を並べて台帳を組めます。
- 21人以上 ── 席の刻みを確認できませんでした。申し込み画面で選べる席数をご確認ください。
- 迷ったら ── Asana Starter。円建てで安く、席の刻みが細かく、自動化もタイムラインも最下位プランにあります。
