Which subscription tracker works in Japan?
Western bank-linked tools do not serve Japanese banks. What works, why carrier billing complicates things, and how to handle a JPY list.
The short answer
Rocket Money and Emma do not serve Japanese banks, so the Western answers do not apply. Two local complications matter more than the tooling: carrier billing through docomo, au or SoftBank puts subscriptions on a phone bill rather than a card, and JPY has no decimal places, which several trackers get wrong.

The tooling situation
Bank-linked detection as it exists in the US and UK is not available for Japanese accounts. Domestic household-finance apps cover some of this ground and are the better local starting point than any Western recommendation.
A manual tracker works identically here because nothing is detected — that is the point of the architecture. The question is only whether it handles JPY correctly, which is a real and specific concern.
Carrier billing is the local complication
A significant share of Japanese subscriptions are billed through the mobile carrier — docomo, au or SoftBank — rather than to a card.
That produces the same blind spot as app-store billing, in a different place. The charge appears on the phone bill as a line among others, and it is invisible to anything reading a bank statement or a card feed.
Check the carrier's own subscription list as a source in its own right, alongside the App Store and Google Play. For many people this is where the forgotten subscriptions actually are.
That makes five sources rather than four: card statements over twelve months, App Store, Google Play, carrier billing, and any PayPal agreements.
JPY has no decimal places
A technical point with a practical consequence.
The yen is a zero-decimal currency: ¥1,290 is 1290 minor units, not 129000. Software that assumes two decimal places everywhere renders Japanese amounts a hundred times too large, or stores them a hundred times too small.
It is a bug that reaches production regularly, because nobody on the development team has a JPY subscription to notice it with.
Check this in any tracker before committing. Enter a subscription at ¥1,290 and see whether the total makes sense. SubTracker handles JPY among its 25 currencies with the correct exponent, but the check takes ten seconds and is worth doing in any tool.
Notes for a Japanese list
Annual contracts and 自動更新. Automatic renewal is common and the notice requirements vary by contract. Record the term and set the reminder at thirty days or more.
Foreign providers billed in USD. The yen amount moves with the exchange rate even when the price has not changed. Record the amount in the currency actually charged rather than a converted figure — otherwise a rate movement looks like a price rise.
Cancelling carrier-billed subscriptions usually happens through the carrier's own portal rather than the provider's, in the same way App Store subscriptions cancel at Apple. Cancelling with the provider alone may not stop the billing.
Der Kompromiss, der dahintersteht
Abo-Werkzeuge zerfallen in zwei Bauweisen, und fast jeder praktische Unterschied folgt daraus.
Bank-verbundene Werkzeuge lesen über einen Aggregator wie Plaid, TrueLayer oder Tink deine Transaktionshistorie und erkennen daraus wiederkehrende Belastungen. Einrichtung: unter einer Minute. Der Preis ist, dass ein Dritter eine laufend aktualisierte Kopie davon hält, wo du überall Geld ausgibst — nicht nur deine Abos, solange die Verbindung offen ist.
Manuelle Werkzeuge stellen diese Verbindung nie her. Du trägst jedes Abo einmal ein, rund zehn Minuten für eine typische Liste. Der Dienst kennt Anbieter, Betrag und Verlängerungsdatum — mehr nicht, weil mehr nie erhoben wurde.
Keines ist grundsätzlich richtig. Wenn du nicht weisst, wofür du zahlst, löst Bankverbindung ein Problem, das manuelle Eingabe nicht anfassen kann. Wenn du deine Liste kennst, zahlst du einen dauerhaften Preis für neun gesparte Minuten.
Was es kostet
Der kostenlose Plan verfolgt unbegrenzt viele Abos, ohne Karte und ohne Ablauf — mit CSV-Import, Kalender-Feed und vollständigem Export. Erinnerungen und Preis-Alarme sind Plus für $5.90/Monat. Family kostet $9.90/Monat und umfasst einen geteilten Workspace für bis zu zehn Personen.

Do Western subscription trackers work in Japan?+
Bank-linked ones do not — Rocket Money and Emma do not serve Japanese banks. Manual trackers work identically anywhere because nothing is detected, provided they handle JPY correctly.
Where do carrier-billed subscriptions appear?+
On the mobile phone bill rather than a card statement, so they are invisible to anything reading a bank feed. Check the carrier's own subscription list — docomo, au or SoftBank — as a source in its own right.
Why do some apps show Japanese prices incorrectly?+
Because the yen has no decimal places and software that assumes two everywhere renders amounts a hundred times too large. Enter a ¥1,290 subscription and check the total before committing to any tracker.
How do I cancel a carrier-billed subscription in Japan?+
Through the carrier's own portal rather than the provider's, in the same way App Store subscriptions must be cancelled at Apple. Cancelling with the provider alone may not stop the billing.
