Tokyo library cards for a 60-day research stay
A foreign passport does not answer every library question. Decide whether you need open shelves, closed stacks, a reading seat, or books at home, then bring the right address proof.
On this page
For a 60-day Tokyo research stay, choose the library by the material you need. Use the National Diet Library for national holdings and closed stacks. Use a municipal library such as Chiyoda when you need ordinary books at the apartment.
Your default is to search the catalog before applying for any card. A library card does not create access to a book held somewhere else.
National Diet Library: one day or full registration
Anyone aged 18 or over may use the National Diet Library's Tokyo Main Library. There are two practical access levels.
A one-day user card gives access to electronic resources and some open-shelf material. It does not let you request the majority of the collection from the closed stacks. The NDL entry guide sends first-time visitors to the Annex and explains that difference.
Official registration unlocks closed-stack requests. The registration rules require identification showing your name, current residential address, and date of birth. A work or school address is not accepted.
Bring the document that proves where you currently live. If your passport does not show the Tokyo address, check the NDL's current identification list before the visit. The library may accept additional recent utility documents when the main ID does not prove the current address, but you should confirm your exact combination rather than assume an apartment contract is enough.
Registration at the Tokyo Main Library can be completed at the Annex counter. The published counter hours are 9:00 to 18:30 on weekdays and to 16:30 on Saturday. Arrive earlier if you also need material that day.
Chiyoda: useful when books need to leave with you
Chiyoda City Library issues cards to people with a current address in Japan, even when they do not live, work, or study in Chiyoda. Apply in person with an original document showing name, address, and date of birth plus the application form. The current registration page does not accept applications by email.
The card color records the relationship to Chiyoda. A person who lives outside the ward receives the blue card. That status changes the borrowing allowance, not whether you may enter.
The borrowing rules currently allow an outside resident to borrow five books or magazines for two weeks. A Chiyoda resident may borrow ten. CDs and DVDs have separate limits.
This is a better fit than NDL when you want a recent book beside your desk for a week. NDL material stays in the library.
Chiyoda Library at Kudanshita is also an evening option. It opens until 22:00 on weekdays, but some services stop 15 or 30 minutes before closing. Check the day's calendar before planning a late registration or closed-stack request.
When the Tokyo address cannot be proved
A 60-day furnished apartment gives you a place to live. It may not give you the exact document each library accepts as proof of current residence.
Do not solve this by writing the operator's office or university address. Both NDL and Chiyoda ask for your residence. Ask the library which combination it accepts for a visitor whose passport shows an overseas address.
You still have useful access while that is unresolved:
- NDL one-day access for open-shelf material and on-site electronic resources
- Public reading rooms that do not require a borrowing card for entry
- Your host university's visitor procedure, when the host has arranged affiliation
- Remote catalog work before the first visit
The default changes only when the book is in closed stacks or must leave the building.
Match the card to the research task
| Need | Start here | What to prepare |
|---|---|---|
| One day with open shelves or NDL terminals | NDL one-day card | Identification; check current entry rules |
| NDL closed-stack material | NDL official registration | Name, date of birth, and current-address proof |
| Borrow up to five ordinary books | Chiyoda card as an outside resident | Original ID showing a current Japan address |
| University collection | The named university library | Host or external-user procedure for that collection |
| Quiet evening reading | Chiyoda Library | Day's hours and any seat or service cutoff |
Do not choose Hongo because the university name is familiar if the item sits at Nagatacho. Do not register at NDL for a novel you want to read at home.
Set up the first research week
- Search NDL, Chiyoda, and the host library catalogs for five real titles.
- Mark each title as open shelf, closed stack, on-site only, or borrowable.
- Check whether your current ID proves the Tokyo address.
- Use NDL one-day access if registration is unnecessary for the first visit.
- Apply for full registration only where the material requires it.
- Photograph each card and save the library calendar offline.
The card is the last step. The first step is knowing which door the material sits behind.
