In April 2024, a small rock event took place in a Shibuya music bar. Five bands, fifty tickets, all proceeds donated to an environmental nonprofit. Nothing particularly remarkable, except that it was the first edition of what would become a consistent, growing series. Two years and eight editions later, Too Hot to Be Cool has put 33 bands on stage, sold 710 tickets, and raised nearly ¥1,500,000 for youth-led climate nonprofits across Vietnam, the Philippines, Thailand, Malaysia, and Indonesia. All volunteer-run. All funded entirely by ticket sales. In April 2026, founder Stéfan Le Dû presented the story and lessons behind the series at Nerd Nite Tokyo. This article is a written summary of that talk. The slides are available here.
In November 2018, Stéfan watched Bohemian Rhapsody in a Tokyo cinema. The film ends with Queen’s performance at Live Aid, the massive 1985 benefit concert that raised millions for famine relief in Africa. Walking out of the theatre, he had a thought: what about doing something like that for climate, here in Tokyo?
The idea was modest by comparison, not Wembley Stadium, but a small livehouse in Shibuya. A few rock bands, a cause, a crowd. Raise some money, make some noise. Then life happened. The idea sat in a corner of his mind while other projects took priority. Then COVID arrived and buried it completely: live music in Japan ground to a halt for the better part of three years.
It wasn’t until November 2023, attending Queens for a Cause, a drag show fundraiser in Shinjuku raising money for an environmental NPO, that something clicked. “Watching that show, I thought: this is possible. This is working. Stop overthinking and just start,” Stéfan recalls. In January 2024, he made the decision. By April 2024, the first Too Hot to Be Cool was a reality.
Two years and eight editions later, THTBC has put 33 bands on stage, sold 710 tickets, and raised nearly ¥1,500,000 for youth-led climate nonprofits across Southeast Asia. Here’s how it was built, and what anyone wanting to do something similar can learn from it.
The concept: simple by design
Too Hot to Be Cool is a volunteer-run rock event series in Tokyo. Every yen from ticket sales, after covering the venue rental, is donated to a youth-led climate nonprofit in Southeast Asia. No salaries, no agency fees, no complicated structure. The math is deliberately simple: venue cost versus ticket capacity equals your donation potential.
Ichigo Bloom has been involved since the beginning, providing organizational support and climate education content for each edition.
The recipe, in 11 steps
1. Finding a venue
The venue is your only real cost in a volunteer-run event. Everything else depends on getting this right. THTBC started at Ruby Room, a small music bar in Shibuya that Stéfan already knew well from playing there with his own bands. A personal contact at the venue helped secure a discounted rental rate. “Start small. Use a place you already know. And always ask your contacts if they can help,” he says. The Tokyo Dome can wait.
2. Finding the first performers
Edition 1 was assembled almost entirely from existing relationships: one of Stéfan’s own bands, a band discovered at an open mic, a friend’s recommendation, a former bandmate’s new project. “Not many people would say yes to a stranger asking them to play for free at an unproven event. But friends do.” Your network is your first lineup.
3. Assembling a crew
Nobody gets paid. You need people who will enjoy helping just for the fun of it. THTBC started with three people: Stéfan organizing, Kaori as Japanese MC, and Charles handling tech and logistics. Charles brought two more: Lisa as English MC and Yoshiki as photographer. “You don’t need twenty people. Not even ten. Start with two or three good ones, and make sure they’re right for the job – not just because they’re your friends.”
4. Committing, and letting others hold you to it
Once bands are booked, a crew is assembled, and tickets are sold, you are committed. That commitment becomes a safety net when life gets difficult. “There was a personal moment before the first show when I almost cancelled everything. But the bands were ready, the crew was ready, every ticket was sold. We went on. And I’m glad we did.” The best reason to involve others early: they will carry you when you can’t carry yourself.
5. Doing the show, and paying attention
Edition 1 is not your best work. It’s the foundation of your best work. THTBC1 had its share of problems: one band arrived at soundcheck without a drummer or bassist, the climate education video clips between sets failed to hold the crowd’s attention, and the venue capacity had been underestimated. “We took notes on everything, and improved the second edition on this basis.”
6. Choosing your cause carefully
THTBC1 donated to WWF Japan, a recognizable name that seemed like a safe choice. The reality was less inspiring: WWF declined to let the event use their logo, and showed little enthusiasm for the partnership. “Our donation was probably invisible to them. From THTBC2 onward, we switched to youth-led nonprofits in Southeast Asia. The difference was immediate: they were genuinely excited, they shared our events with their communities, some sent video messages to our audience.” Find partners who need you as much as you need them.
The Southeast Asian nonprofits THTBC has supported since: Youth Climate Action Network Vietnam, For The Future Philippines, Green Youth Thailand, Klima Action Malaysia, Green Welfare Indonesia, Kids for Kids Philippines, and Save the Children Indonesia.
7. Expanding the lineup
From THTBC2, reaching beyond the personal network became necessary – and humbling. Response rates dropped sharply. Some bands declined politely; others simply never replied. “An important cause doesn’t mean everyone cares. We kept asking until we found the right ones.” Tokyo’s indie rock scene is deeper than most people realize: hundreds of bands, every genre, playing all nights from tiny music bars to larger livehouses. It was already there. THTBC just plugged into it. We also learned to invite back bands who gave great shows, were good to the crew, and helped promote. FUQA, an explosive garage rock duo discovered at a Ruby Room open mic in 2024, have played six of the eight editions.
8. Promoting, the hardest part
Promotion consumes more than half the time and energy spent on each edition. The event doesn’t sell itself yet. Social media alone is never enough: the most effective approach is inviting people one by one, which takes time but works. Most tickets sell in the last 48 hours. “I panicked every time. It’s getting better, but it’s still my number one source of stress in the two weeks before each show.” Ask past attendees to spread the word: most will, but only if asked directly. Partnering with aligned communities (other music events, sustainability organizations) helps reach new audiences and builds the event’s credibility over time.
9. Levelling up
After three sold-out editions at Ruby Room, THTBC moved to 7th Floor, roughly twice the capacity, but also significantly more expensive to rent. The lesson was instructive: ticket sales almost doubled from an average of 60 to 110, but the donation only grew by 25%, because the higher venue cost consumed most of the additional revenue. Scaling up is not as simple as it looks. The key insight: in a volunteer-run event, the main bottleneck is time, not money. The crew stays the same size, the flyer still takes one evening to design, the bands still need one email to book. A bigger venue multiplies impact without multiplying effort, but only if you fill it.
10. Teaming up
Consistency and quality open doors. More Than Music, a Tokyo events organizer and THTBC promotion partner, offered a beach festival slot in Kamakura for summer 2026. UK-based feminist rock NPO LOUD WOMEN said yes to bringing their festival format to Tokyo for a collaboration this November. A bar in Koenji offered free venue space for a side event.
11. Remembering why you started
There will be moments of doubt, exhaustion, and stress. The ticket sales graph going nowhere in the middle weeks. A band dropping out last minute. A promotion campaign that generates silence. When that happens, look at what has actually been built: a community of musicians and attendees who show up for the music and the cause, real money reaching real organizations doing real work in Southeast Asia, and a volunteer crew that keeps coming back because they believe in it. “At some point I realized I’m not the most talented person in any discipline needed for these events. But I’m the one who brought the talented people together. That turned out to be enough.”
Two years in: what the numbers say
- 8 editions (7 main shows + 1 open mic)
- 33 bands on stage (main shows only)
- 710 tickets sold
- ¥1,480,000 raised for climate action in Southeast Asia
- 5 countries supported: Vietnam, Philippines, Thailand, Malaysia, Indonesia
The next chapter: a beach rock festival at Zaimokuza Beach, Kamakura on August 8, 2026, THTBC’s first outdoor event. And on November 14, 2026 at Shinjuku MARZ: Loud Women Fest Tokyo × Too Hot to Be Cool, a 100% women-led rock festival raising funds for climate justice in Asia.
Why it matters beyond the music
Southeast Asia is among the regions most severely affected by climate change – rising seas, intensifying typhoons, droughts threatening food security – while having contributed far less than richer nations to the emissions causing it. ¥1 raised in Tokyo and sent to a grassroots youth organization in the Philippines or Vietnam goes considerably further than the same yen spent locally. THTBC is, at its core, a transfer of resources from one of the world’s wealthiest cities to places where those resources make a real difference.
But it’s also something else: a small argument, made eight times now, that real community – people in a room, making noise together for something that matters – is worth building and protecting. In a world increasingly shaped by algorithm-optimized content and AI-generated everything, a packed livehouse on a Saturday night feels quietly radical.
How you can help
Too Hot to Be Cool runs entirely on ticket sales and volunteer energy. The most useful things you can do:
- Come to the next event, get tickets at toohottobe.cool
- Follow and engage on Instagram, YouTube and LinkedIn
- Share the event with people who might come: word of mouth is still the most effective promotion
- Bring friends. Seriously, this is the one that makes the biggest difference!
And if this story has made you think about starting something of your own – a film night, a food event, a sports competition, anything that brings real people together around something you love and a cause you care about – we hope it has made that feel a little more possible. It doesn’t require a perfect plan, a big budget, or any particular talent. Just an idea, a few friends, and the willingness to figure it out as you go.
Too Hot to Be Cool is a non-profit initiative organized by Studio Ichigo. Follow the series at toohottobe.cool and @toohottobecool.tokyo.
