By [Madhushan](https://allratestoday.com/authors/madhushan/), Founder & Lead Developer · Updated 15 Nov 2026 **Retail board rates.** These are the prices San-ju-San Bank displayed on [its own rates page](https://www.33bank.co.jp/kojin/tameru/gaika/kawase.html) when we last read it. They are indicative, change through the day, and are not official rates. For the reference rate, see the [Bank of Japan](https://allratestoday.com/central-bank-rates-api/boj/). ![](https://allratestoday.com/logos/banks/sanjusan.webp) ## About San-ju-San Bank [www.33bank.co.jp](https://www.33bank.co.jp/) San-ju-San Bank (33 Bank) is a regional bank based in Yokkaichi, Mie Prefecture, formed in 2021 from Mie Bank and Daisan Bank. Its exchange-rate page lists the day’s middle rate and the TTS and TTB for foreign-currency deposits in five currencies. ## ![](https://flagcdn.com/24x18/jp.png) Latest board, read 16 Nov 2026, 03:22 Japan time (1h ago) Bank’s own last-updated stamp: **2026-11-13 (Tokyo)** (as printed on its page, local time). Board shown: **TTB / TTS (foreign-currency deposit counter rate, TTM ± the posted fee)**. Banks outside the Gulf publish several boards for the same currency — counter notes, drafts, transfers, cards — and this page shows one of them, the same one for every bank in Japan so the comparison is like for like. The others are on the bank’s own page. | Currency | Bank buys at | Bank sells at | Mid | Spread | Official 2026-11-11 | Mid vs official | | --- | --- | --- | --- | --- | --- | --- | | ![](https://flagcdn.com/24x18/us.png)`USD` | 158.93 | 160.93 | 159.93 | 1.25% | 158.88 | +0.66% | | ![](https://flagcdn.com/24x18/eu.png)`EUR` | 175.32 | 178.12 | 176.72 | 1.58% | — | — | | ![](https://flagcdn.com/24x18/ca.png)`CAD` | 110.54 | 113.74 | 112.14 | 2.85% | — | — | | ![](https://flagcdn.com/24x18/au.png)`AUD` | 106.78 | 110.78 | 108.78 | 3.68% | — | — | | ![](https://flagcdn.com/24x18/nz.png)`NZD` | 86.6000 | 90.6000 | 88.6000 | 4.51% | — | — | All values are JPY per 1 unit of the currency.

Responses can be cached for five minutes; past-day boards never change. - Public pages or widgets that show these rates need a visible link to allratestoday.com. ## Why use bank board rates through an API? The Bank of Japan official rate is what accounting, tax and customs rules name, but it is not what a customer pays at the counter or in an app. Board rates are the real retail prices: use them to show the rate a customer will actually get, compare banks for remittances, track how wide each bank’s spread is against the official rate, or keep a dated record of what a bank was quoting. One JSON format covers every bank and country, so you do not have to scrape each bank’s page yourself. ## Start calling the San-ju-San Bank board API Free key, JSON responses, hourly board captures with the official rate alongside.

Machine-readable copy: Markdown [https://allratestoday.com/bank-exchange-rate-api/jp/sanjusan.md](https://allratestoday.com/bank-exchange-rate-api/jp/sanjusan.md). JSON needs an API key: `https://allratestoday.com/api/v1/bank-rates/jp/sanjusan`. ## Frequently asked questions ### Is the San-ju-San Bank rate the official Japan exchange rate? No. San-ju-San Bank sets its own buying and selling rates and changes them through the day. The official rate is published once per business day by the Bank of Japan; it is shown in the Official column and is the figure accounting, tax and customs rules refer to. ### Which San-ju-San Bank rate applies when I send money abroad? The sell rate: you are buying foreign currency from the bank. When you convert foreign currency into JPY, the buy rate applies. Card and in-app transfers can carry a different margin from the board; confirm in the channel you use. ### How current is this table? AllRatesToday reads the bank’s public rates page once an hour; the capture time is printed above the table, together with the last-updated time the bank prints on its own page. Rates may have changed since. ### Do you have historical San-ju-San Bank rates? Yes, from 13 Nov 2026 onwards, one board per day. One day: /api/v1/bank-rates/jp/sanjusan?date=YYYY-MM-DD (every plan). A range: /api/v1/bank-rates/jp/sanjusan/history?ccy=USD (paid plans). ## Compare [All Japan banks side by sideBest buy and sell per currency](https://allratestoday.com/bank-exchange-rate-api/jp/)
