Overview
SIPO is a Japanese-language news site that lets readers follow blockchain developments without having to read English. It is written by people who run network infrastructure themselves, so the reporting draws on first-hand operational experience rather than on press releases. It also publishes plain-language guides for readers who want to earn rewards by helping support the network.
The network SIPO covers is Cardano, and the site is published by SITION Group, a Tokyo company whose infrastructure arm operates three Cardano stake pools1. A stake pool is a node run by an operator to produce blocks for the network; anyone holding ADA can delegate their stake to one and share in the rewards, and the coins stay in their own wallet throughout2. The same team is a registered DRep, a delegated representative who votes on governance proposals for holders who assign it their voting power3.
Key Features
- Cardano news written in Japanese. SIPO produces reporting for a Japanese readership, covering network upgrades, governance proposals, funding rounds, and ecosystem events4.
- Reporting from inside the network. Because the same team runs the servers and takes part in governance, articles are built on what the operators see on their own machines and in their own voting work1.
- A published record of every governance vote. SIPO sets out written reasoning for each vote it casts as a delegated representative, so the people who assign it their votes can check whether it decides the way they would5.
- A staking guide that keeps readers in control. The guide walks through the main Cardano wallets, explains how reward timing works, and stresses that delegated ADA stays in the holder's own wallet and is never locked up2.
- A weekly edition in English. The weekly governance round-up is translated in full and carries a sources list plus a note explaining where each figure came from and which claims were dropped for lack of a confirmable source4.
What to Expect
The homepage opens with live dashboards rather than a wall of text. One panel tracks the operator's own pools and voting power; another tracks the wider Cardano network's progress through its accounting cycles, its coin supply, and how many pools are active. Below that, articles are sorted into formats with distinct rhythms: breaking items posted within hours of an event, a morning news digest, diaries covering each accounting cycle, a weekly governance brief, and longer analytical pieces4.
Most of the site is Japanese. English readers get the weekly brief in full translation, which is the governance analysis rather than the daily stream, while site navigation and the homepage dashboards stay in Japanese4. Browser translation covers the rest reasonably well.
Nothing sits behind a login, there is no token, and no account is needed to read. Readers who want to check what they are told are pointed at independent Cardano explorers and at the site's public governance profile, so the pool and voting figures can be verified against the blockchain itself3. The team also introduces its pools on the official Cardano community forum, where questions can be put to it in public6.
Beyond Cardano, SIPO covers Midnight, a privacy-focused network in the same ecosystem, as an official community ambassador, running meetups and workshops in Tokyo and carrying a standing Midnight section inside the weekly brief1. Its parent company, SITION Group, keeps a separate corporate site7.
