How much will a dollar-priced SaaS cost you in yen?ドル建てのSaaSは、円でいくら払うことになりますか
Japan pricing, annual billing, excluding tax. Of the 6 vendors, only 3 publish a yen price list on their own pages: HubSpot, Asana and Shopify. Semrush bills and displays in dollars and euros only, and Squarespace will take payment in yen yet we could not find a yen price list. On monday.com the Japanese-language page still showed dollar prices when we checked.
The 3 vendors that do price in yen are not doing the same thing. Divide the yen price by the US dollar price and the 3 diverge.
Divide yen by dollars and the yen price lists come apart
| Effective rate, yen ÷ dollars | What the conversion really is | How to read this | |
|---|---|---|---|
| HubSpot | Exactly 120.0 on every item | Fixed at 1 dollar = 120 yen | Written in yen, but priced in US dollars underneath |
| Shopify | 125.9 / 127.8 / 147.2, scattered | Independent pricing set for Japan | The vendor states explicitly that it is not converted from US dollar prices |
| Asana | 109.2 / 108.0 (156.1 for the add-on only) | Its own price, rounded in yen | The core plans line up closely; only the add-on is handled differently |
(Calculated in August 2026 from each vendor's own annual prices. HubSpot: 9 items, from ¥840 ÷ $7 to ¥360,000 ÷ $3,000. Shopify: ¥3,650 ÷ $29 / ¥10,100 ÷ $79 / ¥44,000 ÷ $299. Asana: ¥1,200 ÷ $10.99 / ¥2,700 ÷ $24.99 / ¥935 ÷ $5.99)
HubSpot's fixed 120 yen holds without exception. If the market rate is 1 dollar to 150 yen, the annual price of Marketing Professional would be $9,600 × 150 = ¥1,440,000, but it comes to ¥1,152,000 — ¥288,000 a year that the market rate would have added. Because it is fixed, though, the gap disappears the moment HubSpot revises it. Do not read yen pricing as a hedge against currency movements.
Shopify is the only one that gives the basis for its pricing in its official help.
Tax and payment methods are a separate question from yen pricing
| Tax on the displayed price | Official mention of Japanese consumption tax (JCT) | Invoice payment / bank transfer | Changing the contract currency | |
|---|---|---|---|---|
| HubSpot | Excluding tax (stated in the terms of service) | The contracting entity is "HubSpot Japan KK". We could not find JCT itself stated on the vendor's own pages | The terms set a payment deadline of 30 days. Whether a bank transfer can be chosen in Japan could not be confirmed. ACH is the US only | We could not find this stated on the vendor's own pages |
| Asana | Excluding tax (stated in the FAQ) | Yes (JCT is stated to apply) | The official help lists cards and PayPal only | We could not find this stated on the vendor's own pages |
| Shopify | We could not determine whether tax is included | We could not find this stated on the vendor's own pages | Card, Shopify Balance, PayPal, ACH (US) and SEPA (euro area). Japanese bank transfer is not covered | Possible in eligible countries. Applies from the next invoice |
| monday.com | Excluding tax (note beneath the prices) | The tax article makes no mention of Japan | Not available (cheques, money orders and purchase orders are not accepted). Enterprise is handled separately | Not possible after payment (8 currencies) |
| Semrush | Excluding tax (JCT is added to the total charged) | Yes (JCT 10%, no B2B exemption) | Wire transfer on annual billing only. Eligibility depends on the contract amount | We could not find this stated on the vendor's own pages |
| Squarespace | Excluding tax (stated in the help) | Yes (JCT applies, and exemption is stated to be unavailable) | Not available (cheques, bank transfers and purchase orders are not accepted) | Not possible after the first payment (26 currencies) |
All amounts are as of August 2026 and exclude tax. Sources are at the end of the article. JCT (Japanese Consumption Tax) is Japan's consumption tax, ACH is the US bank-account debit scheme and SEPA the euro-area one, and neither works with a Japanese bank account.
Start with the 2 columns on the right. Not one of the 6 vendors confirms on its own pages that it accepts a Japanese bank transfer. Since HubSpot, Shopify and monday.com say nothing about JCT, you will be asking at the quotation stage whether 10% goes on top. On a ¥1,000,000 contract a year that is a ¥100,000 difference. Shopify is the only one where we could not even determine whether the price includes tax: ¥4,380 rides on the ¥43,800 annual Basic plan, and ¥52,800 on the ¥528,000 annual Advanced plan.
The currency is fixed at monday.com on the first payment, and at Squarespace on the first payment or at the point a domain is moved to a trial site with no previous subscription. Both state officially that it cannot be changed afterwards. It is safer to choose on the basis that the currency is settled at the first payment.
If you stay in dollars, how much does the annual figure move?
Annual dollar contracts converted to yen (assumed rates, excluding tax, annual billing)
1 USD = 140 / 150 / 160 yen are all assumptions. The rate actually applied is the one the card issuer uses on the settlement date. Source: monday.com pricing page / Semrush pricing page (August 2026)
| Annual contract in US dollars | 140 yen | 150 yen | 160 yen | How to read this |
|---|---|---|---|---|
| $1,140 (monday.com Pro, $19 × 5 seats × 12, annual billing) | ¥159,600 | ¥171,000 | ¥182,400 | A difference of ¥22,800. About 6 tenths of ¥36,480, the annual cost of 1 seat at 160 yen |
| $1,407.96 (Semrush SEO, $117.33 × 12, annual billing) | ¥197,114 | ¥211,194 | ¥225,274 | A difference of ¥28,160. 14.3% of the annual total = about 1.7 months of use |
The ratio is constant whatever the contract is worth: the gap between 140 yen and 160 yen is 160 ÷ 140 = 1.143 times. The first thing to check is the rate your own budget was built on. Built at 140 yen, it is +14.3% at 160 yen; built at 150 yen, +6.7%. Allow for that spread from the start and no mid-year correction is needed.
On top of this sits the card issuer's handling fee, generally in the region of 1.6 to 2.2%. It is a cost that never appears on the quotation, and Squarespace is the only vendor that mentions it officially.
Who should not buy
monday.com and Squarespace do not suit a company that wants to try 1 year in dollars first and switch to yen the following year. The currency is fixed at the first payment, and switching means creating the account again.
Semrush and Squarespace do not suit a company that wants to settle its treatment as a consumption-tax-exempt business. Both state explicitly that they do not accept exemption on the basis of a business registration number.
Asana does not suit a company whose approval process requires invoice payment and bank transfer. The official help lists cards and PayPal and nothing else.
Shopify does not suit a company that wants the annual figure fixed to the last 1 yen before signing. Whether tax is included cannot be determined, and a spread of a few thousand yen up to just over ¥50,000 a year remains.
If you are still deciding
These 6 products are not substitutes for one another. What follows assumes you have already settled what you are buying, and covers only the choice that comes after that.
Between monday.com and Asana, on currency grounds it is Asana. It has a yen price list, and its Japanese FAQ states both that prices exclude tax and that JCT applies. The gap in money is small: against monday.com Pro at 5 seats, $1,140 a year (about ¥171,000 at 150 yen), Asana Advanced for 5 people is ¥162,000 a year. The difference is about ¥9,000.
If you are weighing Shopify against Squarespace and want the quotation settled first, it is Squarespace. Weigh the range of payment methods and the independent yen pricing more heavily and it becomes Shopify.
Do not count on HubSpot's yen advantage as a fixed cost. Marketing Professional on annual billing is displayed at ¥96,000 a month, but what leaves the account at signing is ¥1,152,000 plus the mandatory onboarding of ¥360,000 = ¥1,512,000 in the first year (¥1,663,200 including JCT). Allow for the ¥288,000 a year that would come back if the fixed 120 yen were revised, and treat it as room for a price rise.
For Semrush the only question is whether you can accept dollar billing. If you can get approval with the annual $1,407.96 set at ¥225,274 on a 160-yen basis, go ahead; if you cannot, look for a different tool.
Whichever you choose, get 2 things in writing: whether the price excludes or includes tax, and whether a qualified invoice carrying a registration number will be issued. Without a qualified invoice, the consumption tax you have paid cannot be deducted from your own tax liability. On a ¥1,152,000 contract a year, ¥115,200 stays as a cost you cannot recover.

The exchange rates (140 yen / 150 yen / 160 yen) are all assumptions, not official figures. The amount actually billed is set by the rate the card issuer applies on the settlement date. Whether the Japanese Shopify pricing page shows prices including or excluding tax, whether the 6 vendors issue a qualified invoice carrying a registration number, whether HubSpot, Asana and Semrush allow the billing currency to be chosen and changed, and which currency monday.com displays when accessed from Japan: we could not find any of these stated on the vendors' own pages. Semrush prices are shown differently on the pricing page and in the knowledge base. Terms change, so please check each vendor's official pages before you sign.
結論を先に書きます。6社のうち円建ての料金表を公式に出しているのは HubSpot・Asana・Shopify の3社。Semrush は請求も表示もドルとユーロだけで、Squarespace は円で請求を受けられるのに円の料金表が見つかりません。monday.com は当方の確認時、日本語ページも$表示でした。
そして円建ての3社も、中身は同じではありません。円の値段を米ドルの値段で割ると、3社で結果が分かれます。
円建ての中身は、割り算をすると分かれます
| 円÷ドルの実効レート | 換算の性格 | この数字の読み方 | |
|---|---|---|---|
| HubSpot | 全項目で 120.0 ちょうど | 1ドル=120円の固定 | 円で書いてあっても、値付けの実体は米ドル |
| Shopify | 125.9／127.8／147.2 とばらつく | 日本向けの独立した値付け | 米ドル価格から換算していないと公式が明言 |
| Asana | 109.2／108.0（アドオンのみ 156.1） | 円で丸めた独自価格 | 本体はほぼ揃うが、アドオンだけ別扱い |
（2026年8月・各社公式の年払価格で計算。HubSpot は ￥840÷$7 から ￥360,000÷$3,000 まで9項目、Shopify は ￥3,650÷$29／￥10,100÷$79／￥44,000÷$299、Asana は ￥1,200÷$10.99／￥2,700÷$24.99／￥935÷$5.99）
HubSpot の120円固定に例外はひとつもありません。実勢が1ドル150円なら、Marketing Professional の年額は $9,600×150＝￥1,440,000 のところ ￥1,152,000 で済み、年￥288,000 を為替に払わずにすんでいます。ただし固定である以上、HubSpot 側が改定すればこの差は消えます。円建てを為替対策と読まないほうがよさそうです。
Shopify だけは、公式ヘルプに値付けの根拠があります。
税と支払い方法は、円建ての有無とは別の問題です
| 表示価格の税 | 日本の消費税（JCT）への公式言及 | 請求書払い・銀行振込 | 契約通貨の変更 | |
|---|---|---|---|---|
| HubSpot | 税別（利用規約に明記） | 契約主体は「HubSpot Japan KK」。JCT自体の記載は確認できず | 規約に支払期限30日の定めあり。日本で振込を選べるかは確認できず。ACHは米国のみ | 記載を確認できず |
| Asana | 税別（FAQに明記） | あり（JCT課税を明記） | 公式ヘルプはカードとPayPalのみ | 記載を確認できず |
| Shopify | 判別できませんでした | 記載を確認できませんでした | カード・Shopify Balance・PayPal・ACH（米国）・SEPA（ユーロ圏）。日本の銀行振込は対象外 | 対象国なら可。次回請求から適用 |
| monday.com | 税別（価格下の注記） | 税の記事に日本の記載なし | 不可（小切手・郵便為替・発注書は受付外）。Enterpriseは別途 | 決済後は不可（8通貨） |
| Semrush | 税別（支払総額にJCTを加算） | あり（JCT10%、B2B免除なし） | 年払のみ電信送金が可。可否は契約金額次第 | 記載を確認できず |
| Squarespace | 税別（ヘルプに明記） | あり（JCT課税・免除不可を明記） | 不可（小切手・口座振込・発注書は受付外） | 初回決済後は不可（26通貨） |
金額はすべて2026年8月時点・税別。出典は記事末尾。JCT（Japanese Consumption Tax）は日本の消費税、ACHは米国の銀行口座引落、SEPAはユーロ圏の銀行口座引落で、どちらも日本の銀行口座では使えません。
この表は右の2列から読んでください。日本の銀行振込を公式に確認できる会社は6社中ゼロです。JCTへの言及がない HubSpot・Shopify・monday.com は、見積の段階で10%が乗るかどうかを自分で問い合わせることになります。年￥100万の契約なら￥10万の差です。税込・税別すら判別できなかったのは Shopify だけで、ベーシックの年払 ￥43,800 で ￥4,380、アドバンスの年払 ￥528,000 で ￥52,800 が動きます。
通貨は、monday.com が初回決済で、Squarespace が初回決済または過去に契約のない試用サイトへドメインを移した時点で固定されます。どちらも後から変えられないと公式に書いています。通貨は初回決済で確定する前提で選んだほうが安全です。
ドル建てのままだと、年額はどれだけ動きますか
ドル建て年額の円換算（為替は仮定値・税別・年払）
1ドル=140/150/160円はすべて仮定。実際の適用レートはカード会社の決済日レート 出典：monday.com料金ページ／Semrush料金ページ（2026年8月）
| 年間の米ドル契約額 | 140円 | 150円 | 160円 | この数字の読み方 |
|---|---|---|---|---|
| $1,140（monday.com Pro $19×5席×12・年払） | ￥159,600 | ￥171,000 | ￥182,400 | 差額 ￥22,800。160円換算の1席分年額 ￥36,480 の約6割 |
| $1,407.96（Semrush SEO $117.33×12・年払） | ￥197,114 | ￥211,194 | ￥225,274 | 差額 ￥28,160。年額の14.3%＝約1.7か月分 |
比率は契約額によらず一定で、140円と160円の差は 160÷140＝1.143倍です。先に確認すべきは、自社の予算がどのレートで組まれているかです。140円で組んでいるなら160円で+14.3%、150円なら+6.7%。この幅を最初から見込んでおくと、期中の補正が要りません。
ここに、カード会社の事務手数料（一般に1.6〜2.2%程度）が上乗せされます。見積書には載らない費用で、公式に触れているのは Squarespace だけです。
使うべきでない読者像
monday.com と Squarespace は、「まず1年ドル建てで試して、翌年から円建てに切り替える」という進め方をする会社に向きません。初回決済で通貨が固定され、切り替えるならアカウントを作り直す話になります。
Semrush と Squarespace は、消費税の免税事業者としての扱いを詰めたい会社に向きません。両社とも事業者番号による免除を受け付けないと明記しています。
Asana は、決裁に請求書払いと銀行振込が要る会社に向きません。公式ヘルプに載っているのはカードとPayPalだけです。
Shopify は、契約前に年額を1円単位で確定させたい会社に向きません。税込・税別が判別できず、年額で数千円から5万円強の幅が残ります。
迷ったら
この6社は互いに置き換えられる製品ではありません。買うものは決まっている前提で、決まったあとの分岐として読んでください。
monday.com と Asana で迷うなら、通貨の観点では Asana です。 円建ての料金表があり、税別であることとJCTがかかることを日本語FAQに書いています。金額差は小さく、monday.com Pro 5席・年払 $1,140（150円で約￥171,000）に対し Asana アドバンス5人・年払は ￥162,000。差は約￥9,000です。
Shopify と Squarespace で迷っていて、見積を先に確定させたいなら Squarespace です。 決済手段の幅と円建ての独立価格を重く見るなら Shopify になります。
HubSpot は、円建ての有利さを固定費として当てにしないでください。 Marketing Professional の年払は表示 ￥96,000/月ですが、契約時に出ていくのは ￥1,152,000＋必須オンボーディング ￥360,000＝初年度 ￥1,512,000（JCT込 ￥1,663,200）。ここに、120円固定が改定されたときの年￥288,000 を値上げ余地として見ておくと安全です。
Semrush は、ドル建てを受け入れられるかどうかだけが分岐です。 年払 $1,407.96 を160円で ￥225,274 と置いて稟議を通せるなら進む、通らないなら別のツールを探す、という判断になります。
どれを選ぶにせよ、税別か税込かと、登録番号入りの適格請求書が出るかの2点は書面で取ってください。適格請求書がないと、支払った消費税を自社の納税額から差し引けません。年￥1,152,000 の契約なら ￥115,200 が控除できず費用に残ります。
