After-school care: the registered club, the open room, and what a full club does next

When school ends, a Japanese elementary child does not automatically stay in the building. The supervised place parents apply for is the after-school children's club (放課後児童クラブ, hōkago jidō kurabu), which wards usually call 学童クラブ (gakudō kurabu). The Children and Families Agency defines it as care, after lessons, for elementary pupils in grades 1 to 6 whose parents are out in the daytime because of work or a similar reason:

保護者が労働等により昼間家庭にいない小学生（１～６年生）に、授業の終了後に学校や児童館等の施設を利用して適切な遊び及び生活の場を与えて、その健全な育成を図る事業。

Parents call the tight spot at the start of grade 1 the 小1の壁 (shōichi no kabe, the grade-1 wall). The agency's last full survey, 1 May 2025, is blunter. Of 16,330 children nationwide who had applied and could not be registered, grade 3 was the largest group (3,305), then grade 1 (1,966) and grade 2 (1,805). The waiting list is not only the first year.

The national picture in May 2026

A flash count as of 1 May 2026, published 14 July 2026, is still preliminary. The agency warned that municipalities may revise it. A fuller figure, and a flash as of 1 October 2026, were planned for around late December 2026.

	1 May 2026 (preliminary)
Children registered in a club	1,602,037 (up 31,392 on the year before)
Children who applied and were not registered	14,713 (down 1,617)
Of those, already using some other after-school place the municipality is involved in	3,030
Still needing a place after that subtraction	11,683
Tokyo registered / not registered / still needing a place	149,169 / 2,550 / 1,554

The agency says both the register and the waiting list tend to shrink later in the year. A May figure can still be revised, and it is not a seat in April. On the same flash, Shinjuku had 2,431 registered and 5 not registered. Setagaya had 9,531 registered and none waiting.

Alongside the club, municipalities run 放課後子供教室 (hōkago kodomo kyōshitsu), an after-school children's classroom: a programme in the school that is not the same legal service as the club. The full survey as of 1 May 2025 counted 6,595 clubs where children registered at the club could also join that classroom's activities inside the same school. That is a link between two programmes, not a statement that every school has both.

How one ward splits the afternoon

Shinjuku, for the year April 2026–March 2027, publishes three different things.

The club's regular use (定期利用, teiki riyō) is staffed care. A parent qualifies by being out, Monday to Saturday, at least three days a week, from noon until 18:00 including the commute, for at least four hours. Childcare leave counts only until the end of the month in which the child the leave is for turns two. On weekdays the basic hours are the end of lessons until 18:00, with an extension to 19:00. On Saturdays, substitute holidays and long breaks, basic hours are 9:00–18:00, with an early extension 8:00–9:00. The club is closed 29 December–3 January.

The basic fee is 6,000 yen a month, or 4,000 yen for a second and later child in the same household already on regular use. The extension is 200 yen a time, capped at 2,000 yen a month, or 2,000 yen for the month as a block. Grades 1 to 3 are accepted even over capacity, and so is a child with a disability through grade 6. From grade 4, a seat exists only if there is room, higher-priority children first. Skip the pause form and the fee still runs. An exemption (livelihood protection, a specified China-returnee benefit, or no resident tax that year) starts the month you apply. Last year's approval does not carry over.

ひろばプラス (Hiroba Plus) is the open after-school room (放課後子どもひろば) at elementary schools near a club that is expected to overflow, with some club functions added: later hours, an optional snack, attendance, a contact notebook and a parent meeting. The work test matches the club. The fee is free. The snack, if you want it, is 2,000 yen a month, with the same exemption groups. Weekdays run until 19:00, and long breaks from 8:00, but Saturdays, Sundays, public holidays and 29 December–3 January are closed. After 18:00 a parent pickup is the rule. A new first grader may start on 1 April. You cannot hold Hiroba Plus and a club registration (regular, or the school-holiday type) for the same period.

The ordinary ひろば, without the plus, is applied for at the school's own room. Shinjuku announces that start date at the new first-graders' meeting. Moving between the club and Hiroba Plus is, in principle, for a house move or a similar reason. A child in grade 4 or above who leaves the club may find no road back if the club is over capacity.

What goes wrong

The club and Hiroba Plus cannot be held for the same weeks. Grade 4 is when a full Shinjuku club can say no. A May waiting list is not the April list: the agency says the year-end numbers are lower, and that the May 2026 flash can still be revised. Nerima and Setagaya publish their own April 2027 windows in Nerima's club article and Setagaya's club article. Shinjuku's 6,000 yen is Shinjuku's. A private programme you pay yourself is not in these tables.

Shinjuku's bundled window, 5 November–5 December 2025, is over. The pages say the later schedule was revised on 6 October 2026. The new dates are on that schedule.

What to do now

• Decide which thing you need: supervised care until 18:00 or later, most days, or a room in the school with a parent who can be more flexible.
• In Shinjuku, read the schedule revised on 6 October 2026 before you assume a deadline, and file at the club you want. Desk for the scheme as a whole: Children's General Center, 7-3-29 Shinjuku, phone 03-5273-4544.
• If you need a fee exemption, file it. A previous year's approval does not renew itself.
• If the club is full and your child is in grade 4 or above, ask whether Hiroba Plus is offered at that school, and what happens if you later want the club back.
• Outside Shinjuku, use your municipality's club page. The national count tells you seats run out. It does not enrol your child.
