The Entra ID Problem Nobody Warned You About
A company opens an office in Tokyo. HQ provisions Microsoft 365 licenses through their global Enterprise Agreement, connects the tenant to their Entra ID (formerly Azure AD), and assumes the Japan team is set up. Then reality sets in.
User display names need to be in Japanese for internal directories but in English for global address lists. Conditional access policies written for US office IP ranges block everyone in Japan. The Japanese staff cannot read the IT documentation written by the team in Chicago, so they invent their own workarounds — personal OneDrive accounts for sharing, LINE instead of Teams, local file servers that nobody at HQ knows about. Within a year, the Japan office is running a shadow IT operation inside a perfectly good Microsoft 365 tenant.
eSolia fixes this. We're based in Tokyo and we work with Microsoft 365 every day in both Japanese and English. We handle everything from CSP license procurement through a Japanese distributor to Entra ID configuration that accounts for how a bilingual office operates. The difference between what Microsoft 365 can do and what it does for your Japan team comes down to how it's configured and administered — and that's what we do.
Microsoft 365 works best when the whole team is on the same platform — configured for how they actually work.
Licensing and Deployment
CSP licensing in Japan: Microsoft 365 licensing here typically goes through a Cloud Solution Provider channel. That means billing can be structured for Japanese fiscal year alignment (April to March), consumption tax handling follows local requirements, and support escalation goes through a Japanese-language path. We sell and manage licenses as a CSP — we adjust seat counts monthly, mix plan tiers within your organization, and handle the billing relationship directly.
Right-sizing plans by role: Business Basic makes sense for frontline workers who only need web-based apps and email. Business Premium adds device management and advanced security — essential if you need to control endpoint compliance without deploying a separate MDM. Enterprise E3 and E5 plans add compliance, archiving, and advanced threat protection for organizations with regulatory obligations. We audit your current usage and recommend plans by role rather than giving everyone the same license.
Migration and deployment: We cover Exchange Online mailbox provisioning, OneDrive configuration, SharePoint site structure, and Teams rollout. For companies migrating from on-premises Exchange or a Japanese hosting provider (many Japan offices still use local SI vendors), we handle the mail migration with coexistence during cutover so nobody loses access to their inbox. Entra Connect gets configured if you're keeping an on-premises AD, or we migrate to cloud-only identity if that fits better.
Security Administration
Microsoft 365 has a deep security stack, but most of it sits dormant until someone configures it. Our ongoing security administration keeps your tenant hardened as your organization changes — people join, leave, get promoted, or change roles, and the security configuration needs to track those changes.
Conditional access and threat protection: MFA enforcement, conditional access policy management (with rules that account for Japan-specific conditions like office IP ranges, VPN connections from Japanese ISPs, and mobile device usage patterns), and regular access reviews. We manage Defender for Office 365 policies — Safe Links, Safe Attachments, anti-phishing rules — and tune them to reduce false positives without opening gaps.
For organizations that need a focused initial security hardening, see our M365 Security Essentials solution — a 2–3 week project that establishes MFA, conditional access, email authentication, and Zero Trust deployment. This page covers the ongoing administration that keeps that foundation solid afterward.
DLP and compliance: Data Loss Prevention, compliance labels, and audit log monitoring are configured based on your industry requirements. Japanese subsidiaries of global companies often need to satisfy both HQ compliance standards and Japanese data protection regulations (APPI), which occasionally conflict — we know where those conflicts arise and how to resolve them.
Hybrid meetings between Japan and overseas offices need more than a webcam — configuration and testing make the difference.

Teams Governance and Collaboration
Teams governance is where most Microsoft 365 deployments quietly fall apart. Without rules, staff create teams and channels freely. Within six months, you have dozens of abandoned teams, channels with names in mixed Japanese and English, and files scattered across team SharePoint sites that nobody can find.
We set up Teams with a governance framework before rolling it out: naming conventions that work in both languages, team creation policies that route requests through approval, channel structures that match your actual organizational units, and retention policies that prevent the accumulation of stale content. Guest access gets configured deliberately — Japanese companies often need to collaborate with partners and suppliers through Teams, and the default guest settings are either too open or too restrictive.
Meeting room integration (Microsoft Teams Rooms devices, third-party hardware) is configured with calendar resource booking through Exchange Online. For hybrid meetings between Japan and overseas offices, we handle the audio/video configuration and test it with real calls before declaring it ready, because a conference room setup that works fine for domestic calls often has latency or echo issues on international connections.
Power Platform (Power Automate, Power Apps, Power BI) is available in most M365 plans but rarely used well. We help teams build practical automations — approval workflows, data collection forms, simple reporting dashboards — that replace manual processes without requiring developer resources.
Ongoing Support and Training
Microsoft changes its admin portals, renames products (Azure AD became Entra ID, Office 365 became Microsoft 365), and ships new features with regularity. We track these changes and handle the administrative impact so you don't have to. Our ongoing support covers tenant administration, user account lifecycle management, license optimization reviews (if you are paying for E5 licenses that E3 would cover, we will tell you), and troubleshooting.
When something breaks — Outlook sync issues, Teams call quality problems, SharePoint permission errors — we troubleshoot in both Japanese and English. Try explaining a conditional access block to a Japanese staff member using only English error messages and you'll see the difference bilingual support makes.
Training sessions run in the language your staff works in. We cover the practical tasks people struggle with: Outlook calendar sharing, Teams meeting etiquette for Japanese business culture (camera on or off, muting conventions, chat versus email for different types of communication), SharePoint document co-authoring, and OneDrive sync troubleshooting. Admin training covers the Entra ID and Exchange admin center tasks your internal IT coordinator handles between our support visits.
