JapanCalc - Japan Travel Guide
FiX-Marketing
Welcome to Japan.
You're at the ticket gate. The light just turned red. Behind you, a line
is forming. Your phone shows a currency you don't quite trust — was that
taxi fare fair? Should you tip? Is that onsen tattoo policy about to
ruin your evening?
Japan defies every expectation, in the best way. JapanCalc is your quiet
companion through all of it.
Four tools. One price. $4.99, paid once.
―――――――――――――――――
PRICE · 値段 (nedan) — Currency Converter
A price tag reads ¥6,880. Before the mental math even begins, JapanCalc
shows you: ¥6,880 = $42.92. Yes, you can afford it. Yes, buy it.
Switch between Shopping (10%) and Take-out (8%) tax rates with one tap.
No guessing, no awkward moments at checkout. Works completely offline —
deep underground at Tokyo Station, it's always there.
―――――――――――――――――
ASK · 聞く (kiku) — Anything About Japan, Answered
Should you tip? Can you keep your shoes on? What's the deal with tattoos
and onsen? How do you even book a Shinkansen seat? Ask JapanCalc anything,
in plain language, and get a real answer — not a wall of search results.
Instant answers are built in for the questions every traveler asks:
tax-free shopping, tipping, onsen tattoo rules, and Shinkansen booking.
The awkward moment disappears before it happens.
―――――――――――――――――
RIDE · 改札 (kaisatsu) — Trains, IC Cards & the Moment Things Go Wrong
IC cards. Ticket gates. Platform numbers. Japan's railway system is the
finest on earth — and one of the most overwhelming for first-time travelers.
JapanCalc plans your route with AI, explains which IC card to get, and
covers the full JR Pass picture. And when the gate flashes red, your card
won't scan, or you've boarded the wrong train — a dedicated Trouble button
gives you a clear answer in one tap, no waiting, no searching.
By day one, you'll be following the app. By day three, your friends will
be following you.
―――――――――――――――――
TRIP · 旅 (tabi) — Your Trip, Quietly Recorded
Every time your heart moves, money moves with it. The sushi counter in
Tsukiji. The arcade you ducked into during the rain. The tiny shop you
almost walked past.
TRIP notices — not just the numbers, but the moments behind them. Each
morning, it greets you with a few warm words about the day before. A quiet
diary, written while you were busy falling in love with Japan.
―――――――――――――――――
線香花火 · FAREWELL — The Sparkler
A senkō hanabi sparkler burns for about thirty seconds. Everyone goes
silent and watches until the last spark falls. That's the whole point of it.
On the day you leave Japan, JapanCalc does something no other travel app
does: it reads back through everything you recorded — the places, the
spending, the moments your heart moved — and turns your trip into a story.
A farewell letter, composed by AI. Felt only by you.
Then, like the sparkler, it goes quiet. Brief. Brilliant. Never forgotten.
―――――――――――――――――
$4.99. Once. Yours forever.
No subscription. No ads. No account required. Less than a coffee and an
onigiri — for a companion through your entire journey: before, during,
and the memory after.
A journey should have a beginning and an end.
8 LANGUAGES
English, 日本語, 中文(简体/繁體), 한국어, Français, Español, العربية
Currency conversion works fully offline — even deep underground with no
signal. ASK and RIDE use AI to give you real-time help, so an internet
connection keeps them at their best.
―――――――――――――――――
Made in Japan. Made for you.
Every day at Tokyo Station, travelers from around the world stand frozen
at the ticket gates — bags in hand, the rest of Japan waiting just beyond.
JapanCalc was made in the spirit of おもてなし (omotenashi) — wholehearted
hospitality, no strings attached.
We hope you fall in love with every bowl, every temple, every train.
We hope you come back.
